Biography:

Susan Haddock educational background includes a BS in Environmental Horticulture from the University of Florida; BS in Biology from Old Dominion University and a MBA from the University of California, USA respectively. She is currently working in the University of Florida Institute of Agricultural Sciences County Extension Agent III. She has served the commercial horticulture industry of Hillsborough County and southwest Florida since March 2010 by providing educational resources, programs, diagnostics and site visits in the areas of sustainable urban horticulture practices, water quality and conservation, integrated pest management, and pesticide safety. 

Abstract:

Situation: The State of Florida projects its current population of 20 million will grow to nearly 26 million over the next two decades, and will increase in tax on available water resources as well as increase in surface and ground water pollution. A recent strategic study on the state’s water resources, “Water 2070: Mapping Florida's Future - Alternative Patterns of Water Use in 2070", found that the state’s ongoing Florida-Friendly Landscaping™ (FFL) program is fundamental to reducing future water demand and protecting water quality.

Methodology: The University of Florida, Institute of Food and Agricultural Sciences (UF/IFAS) administers FFL, with state and federal funding provided by the Florida Department of Environmental Protection and the US Environmental Protection Agency. FFL provides educational outreach to homeowners through its Florida Yards & Neighborhoods program and to commercial landscape professionals through the Green Industries Best Management Practices (GI-BMP) program. These programs promote quality landscapes through appropriate landscape design, while reducing nonpoint source pollution through reduced water, fertilizer and pesticide use. The FFL program educates citizens through a statewide network of Extension agents affiliated with UF/IFAS Extension. The agents coordinate an extensive volunteer network of over 4,000 citizen Master Gardeners and work cooperatively with over 41,000 landscape industry professionals certified (from 2006 through 2016) in GI-BMP. FFL legislation requires GI-BMP training and state licensing for all landscape workers who apply fertilizer commercially.

Results: Florida state legislation, passed in 2009, found that FFL serves a compelling public interest in water conservation, protection and restoration, that participation by homeowner associations and local governments is essential, and that deed restrictions or local ordinances may not prohibit FFL use by homeowners. During 2016 alone, the FFL program directly reached 155,750 homeowners through in- person workshops, conducted 6,051 home consultations, and certified 4,051 persons in GI-BMP. Other countries can easily replicate this program.

Stefan Gandev is a Full-Time Professor at the Fruit-Growing Institute in Bulgaria. He is the Head of the Department of Propagation, Breeding and Biotechnologies and the Director of the Institute. In the past decade he has focused his research on walnut propagation and growing. His scientific interests are also focused on problems related to fruit tree architecture, pruning for better fruit-bearing and organic production of fruits. He is the author of over 80 publications and three monographs. He is a Member of international committees and has chaired a many scientific sessions in international fora.

Abstract:

Statement of the Problem: Propagation of walnut (J. regia L.) is more difficult compared to most of the fruit species. It is due to the low rate of callus formation and the presence of high concentration of phenolic compounds. Because of walnut heterozygosity, propagation by seeds does not lead to inheritance of the characteristics of a certain variety. For that reason, different methods of walnut propagation have been investigated all around the world.

Aim: The aim of the present study is to discuss the modern techniques for walnut propagation.

Methodology & Theoretical Orientation: Two new methods of walnut propagation were presented in the survey – hot callus and epicotyl grafting. All the details of the technological process were discussed – rootstock production, scion selection, technique and time of grafting, temperature conditions, etc. The results obtained were compared to other widely accepted and popular methods and theoretical and practical conclusions were made, which result in increasing the percentage of successfully propagated walnut plants.

Conclusions & Significance: It was concluded that the described methods of epicotyl grafting and hot callus are suitable for walnut propagation and they can be applied in practice in industrial scale propagation of the fruit species.

Abstract:

Statement of the Problem: The cocoa agroforestry system (CAS) is one of the most important in the state of Tabasco, Mexico. The CAS can store quantities of carbon (C), even higher than some natural forests. Under humid tropics conditions, the size of the soil organic matter (SOM) stores is small and rapidly degrades, so that soil fertility can be quickly depleted making the agroecosystem highly dependent on the supply of fertilizers.

 

Objectives: The objective of this research was to measure the concentration of soil organic carbon (SOC) and other variables indicating soil fertility, in a chronosequence of pastures that were established on cocoa plantations.

 

Methodology & Theoretical Orientation: The research was carried out at Jalpa de Méndez, Tabasco, Mexico. Sites that were previously CAS were selected and that currently record a change in land use. With the years of change reported by farmers, the following intervals were established: 1-5 years (PZ 1-5), 6-10 years (PZ 6-10) and 11-20 years (PZ 11-20). At each site samples were taken at three depths (0-10 cm, 10-20 cm and 20-30 cm).

 

Results: The results indicate that during the first years, the land use changed (PZ 1-5) given a slight decrease in the levels of SOC. Although these increase in the pastures of 6-10 years (PZ 6-10), inclusive above the levels recorded in CAS 20-35. However, this increase is temporary, since it is observed that these storage levels decrease in pastures 11-20 years (PZ 11-20). In the long term, the change of land use from CAS to pasture reduces the SOC stores and some chemical and physical properties. In the first years of the change the reduction of the SOC content is reflected in the young pastures (PZ 1-5). In older pastures (PZ 11-20) the chemical and physical properties declined and the content of the SOC decreases to level below CAS 20-35.

Abstract:

Statement of the Problem: Chilli is one major vegetable crops of the world with India being one of the important producers. Most of the commercial varieties grown in the state were found susceptible to powdery mildew and chemical control has been the most effective method adopted by farmers to protect their crops. But continuous use of same fungicide has developed resistance against powdery mildew pathogen (Leveillula taurica), reduced the appeal of chemicals and has led to the search of new fungicides. The study was conducted to evaluate a new fungicide to control the disease. Efficacy of different dosages of IKF-309 180SC was tested in the field condition along with Azoxystrobin 23% SC and Tebuconazole 25% WG.

Methodology: Field experiment was carried out to evaluate the performance of new fungicide IKF-309 180SC and compare with two other fungicides against powdery mildew disease at University Instructional Farm, West Bengal, during winter season. The four different dosages of fungicide IKF-309 180SC (@72g ai, 90g ai, 108g ai and 126 g ai/ha), Azoxystrobin 23% SC (@125g ai/ha) and Tebuconazole 25% WG (@ 187.5g ai/ha) were sprayed over the crop against this disease, three sprays of each chemical with desired concentrations were applied starting from the first appearance of the disease at ten days interval.

Findings: The results showed that IKF-309 180SC @ 126 g ai/ha and IKF-309 180SC @108 g ai/ha significantly reduced the disease and also increased the yield in comparison to other fungicides and untreated control. Among the six meteorological factors temperature (Maximum Minimum) relative humidity (Maximum Minimum) and rainfall were significantly co-related with disease progression.

Conclusion & Significance: In West Bengal condition the powdery mildew could be controlled by three sprayings of IKF-309 180SC @108 g ai/ha. Temperature, relative humidity and rainfall correlated on disease progression but no effect could be found on sunshine hours.

Abstract:

Statement of the Problem: Chilli is produced in India having the highest share of production of spice crops, vulnerable to many diseases and chemical control has to be the only option adopted by farmers to protect their crops from biotic pathogens. Continuous use of conventional chemicals caused resistance against these pathogens. Second generation chemicals have proved as a new ray of hope in management of diseases.

Methodology: Field experiment was conducted to find out the effect of different metrological factors on severity of bacterial leaf spot, Cercospora leaf spot and dieback of chilli caused by Xanthomonas campestris, Cercospora capsici and Colletotrichum capsici respectively under six chemicals treatment during 2017-18. The four different dosages of Kasugamycin 3% SL @ 22.5 g, 30.0 g and 37.5 g a.i. h-1, Azoxystrobin 23% SC @ 125 g a.i. h-1 and another one pre-mix chemicals Metiram 55% + Pyraclostrobin 5% WG @ 1050 g a.i. h-1 were applied in field over the crop against this diseases, three sprays of each chemical with desired concentrations were applied starting from the first appearance of the disease at ten days interval. Different prediction equations were developed for each chemical treatments separately through step down multiple regression analysis.

Findings: Different meteorological factors had different effect on increase of disease severity of these three different diseases. It was found that all the chemicals reduced the three diseases significantly in comparison to untreated control. The progress of disease severity was also minimum in these treatments. Kasugamycin 3% SL @ 30.0 g a.i. h-1 showed maximum reduction in disease severity with high fruit yield in comparison to other treatments. Among the meteorological factors considered only average temperature (Tmin), RHmin and total rainfall (Rt) were found to act positively and significantly whereas bright sunshine hours had negatively significant effect on progress of severity for the three diseases in chilli.

Silvia M Avilés has her expertise in soil fertility, Sustainable Use of Soil and Water Research Group. Her evaluation is based on fertility in the soil on agricultural production systems in arid zones that let to get information to improve the management of fertilizers, soil and water, taking in account climate change and greenhouse gases emissions. She has been working for several years in research, evaluation and teaching in diferent universities.

Abstract:

Conventional tillage systems in the production of agricultural crops often, use excessive application of nitrogen fertilizer, which is a source of generation of greenhouse gases (N₂O and CO₂). The information regarding the assessment of greenhouse gases emissions in conventional fertilization a system, which is most widely used in the Mexicali Valley, is limited. The aim of this study is to evaluate the CO₂ emission, organic carbon and soil nitrogen related to the application of nitrogen fertilizer in a soil cultivated with wheat under conventional tillage in the Mexicali Valley, Baja California. The experimental plot, with a soil Aquic Haplotorrert was cultivated with wheat (Triticum durum), with applications of nitrogen fertilizer, urea, at doses of 0, 200 and 400 kg ha^-1. Organic carbon was measured by Walkley & Black method. Soil samples were incubated and CO₂ emanated from the treatments was measured after 4, 22, 46 and 142 hours of incubation. Nitrogen mineralization (NO₃^-) during the crop cycle was obtained from KCl extraction and Kjeldhal method. The tendency was described by a lineal function (y = ax + b), a statistical means trial test was carried out (Tukey a=0.05). Organic carbon values were between 0.87 to 1.02%, not much difference was found at different doses. The emission of CO₂ was 194, 247 and 238 mg/g/h for doses 0, 200 and 400 Kg N ha^-1 respectively, and there was not much significant difference (p>0.05). The magnitude of the nitrogen mineralization was 753, 942 and 1125 mg N for doses 0, 200 and 400 Kg N ha-1 respectively, with differences (p>0.05) between them. Highest doses of nitrogen applied to the soil does not necessarily correspond to a higher emission of CO₂ or organic carbon, but increase (p<0.05) the nitrogen mineralization, at least under evaluated conditions.

Huajun Wang has her specific expertise and interests in the area of crop improvement and germplasm enhancement, particularly focusing on plant adaptive responses to environment, such as salinity, drought, nutritional disorders, biotic stresses. He is also interested in to apply high throughput methods to screen crop germplasm for stress tolerance and identify QTLs conferring abiotic and biotic stress tolerance to salinity, drought, nutrient deficiency, and fungal disease. The ultimate goal of his research is to improve crop yield and quality to achieve agricultural sustainability under abiotic and biotic stress conditions.

Abstract:

Soil salinization has become a major challenge for sustainable development of global agriculture. Given the limited range of genetic diversity in salt tolerance within traditional crops, stress tolerance mechanisms and genes must be identified in extreme halophytes and then introduced into traditional crops. Halogeton glomeratus (H. glomeratus) is a succulent annual halophyte and is one of the most widely distributed halophytes in Central Asia and arid regions in northwestern China. However, little is known about the physiological and molecular adaptive mechanism of tolerance to salt in this species. For this study, we analyzed the salt tolerance mechanisms of H. glomeratus under different NaCl stress conditions using morphology, cytology, physiology, biochemistry, and molecular biology approaches. Our results showed that H. glomeratus has a robust ability to tolerate salt and belongs to tolerance to osmotic stress category halophytes. The restrictive absorption of Na⁺ into roots and compartmentalization of Na⁺ into vacuoles of mesophyllous cell were considered to be the most critical aspect of salt tolerance in H. glomeratus. Then, three genes (HgS2, HgS3, and HgS4) were identified as candidate genes for drought resistance and salt tolerance in plants. These findings provide new insights into the molecular mechanisms that underlie salt tolerance of H. glomeratus and abundant gene resources to improve salt tolerance in plants. But so far we were unable to clearly address the question of how sodium is compartmentalized in the vacuoles and absorbed restrictively in roots of H. glomeratus. We speculated that different sodium transporters may be present in H. glomeratus and may efficiently compartmentalize sodium in the vacuoles and restrictive absorb in roots. Certainly, it is necessary to the further study to characterize sodium transporters in H. glomeratus.

Abstract:

Statement of the Problem: Many researchers have reported the importance of good agriculture practices in many plants or crops plantation. Four major activities in field maintenance of cocoa plantation included pruning, fertilization, sanitation and harvesting. Cocoa yield is much depended on these factors. However, many farmers only adopted some practices and left others, especially on sanitation practices. In addition, some other farmers do all the practices such as pruning, fertilizer application and sanitation, but not in a proper way. Therefore, they did not achieve the desired yield. This study is trying to indicate the main factors that influenced the cocoa yield in field and the effect when some of those practices were not carried out properly.

Methodology & Theoretical Orientation: Four different practices were adopted in 12 years old cocoa research blocks. One of the block was maintained with complete field activities which included proper pruning, proper fertilizer application and proper recommended sanitation practices. Other blocks were varied where some of block only adopted one or two good practices. Parameters for this study included harvested cocoa pod, potential yield of cocoa dry bean, infection by pest and disease and damaged by mammalian pests. All data were recorded at monthly interval for two years.

Findings: The most significance practices that contributed to the yield in cocoa plantation are sanitation and pruning. Cocoa yield was not severely affected when there was no fertilizer applied might be caused by the residual left from the previous fertilizer program. Without good agriculture practices, the incidence of major cocoa pest and disease has increased.

Conclusion & Significance: High yielding cocoa can be achieved through fully good agriculture practices for cocoa management. Proper sanitation, pruning and harvesting all ripe pods are very important to increase productivity.

Mahya Tavan pursued her BSc (Hons) in Horticultural Sciences at the University of Tehran, Iran. She has started her research on nutritional quality of microgreens and soilless systems in 2017. Her main area of research interests is evaluation of the effects of environmental factors on quality of leafy vegetables by implementing non-destructive methods.

Abstract:

Proper selection of environmental conditions such as light quality, intensity and day length is necessary for efficiently producing high quality nutritional food in indoor farms. Different day lengths impact plant growth and development. In addition, light management is an important economical factor affecting the final cost of the produce. In this experiment, hydroponically-grown kale (Brassica oleracea L. var. acephala) microgreens were studied under different day length regimens of 12 (moderate), 14 (long) and 18 (extremely long) hours, simulated by light emitting diodes (LEDs) in an environmentally controlled growth room. Mineral composition, canopy cover, SPAD chlorophyll meter readings (SCMR) and yield of microgreens were measured and plants were monitored using infrared thermal and visible imagery techniques during the growth period. Results showed that, while daylength differences did not influence significant differences in yield and canopy cover, microgreens grown under long light regimen accumulated significantly higher concentrations of manganese (Mn), iron (Fe) and calcium (Ca) (0.59, 0.89 and 66.4 mg per 100 g fresh weight (FW) respectively) compared to moderate day length (0.45, 0.78 and 57.9 mg/100 g FW respectively). Extremely long light regimen also resulted in higher Mn, Fe and Ca (0.59, 0.89 and 66.4 mg/100 g FW respectively) but these were not significantly high enough to justify the additional energy costs. Similarly, the leaves showed significantly higher SCMR values in long (54.3) and extremely long (60) than the moderate (46) day length treatments. No statistically significant differences in SCMR, mineral content, canopy cover and yield were observed among microgreens grown in 14 and 18 hours light conditions. These results suggest that a 14 hours of day length regimen is optimal for improving the nutritional quality of kale microgreens without additional micronutrient fertilization.

Saurabh Singh, currently Ph.D. scholar at IARI, New Delhi, India, is working on Genetic studies on snowball cauliflower (B. oleracea var. botrytis) using CMS and DH lines. He has also standardized the doses of NaCl sprays for the maintenance of S-allele lines of B. oleracea during M.Sc. programme. Current research focus is on study the heterosis using CMS and DH lines in cauliflower and agronomic and molecular characterization of CMS lines and confirming the origin of cytoplasm types in the CMS lines of cauliflower using mitochondrial markers. He has also published 6 research papers/review papers and one book chapter with CRC press USA. 

Abstract:

Snowball or European summer cauliflower (B. oleracea L. var. botrytis) is the main vegetable crop in Indian sub-continent cultivated during winter season. However, this crop is now cultivated year round after development of high temperature tolerant cultivars and hybrids. Cytoplasmic male sterile (CMS) system is the most attractive and widely used mechanisms in hybrid seed production of B. oleracea vegetables. CMS, which is determined by plant mitochondrial genomes, is associated with the failure to produce functional pollen, and many mitochondrial genes that govern CMS can be suppressed by the products of one or more nuclear genes known as fertility restorer genes (Rf). At least 14 mitochondrial genes that determine CMS have been characterized as open reading frames (ORFs) comprising segments derived from mitochondrial gene-coding and gene-flanking sequences and from sequences of unknown origin. Many cytoplasmic male sterility (CMS) systems have been elaborated in the cultivated Brassica species viz. pol, ogu, tour, nap, hau, Shan 2A, Moricandia arvensis etc. However, so far, the most widespread system used in Brassica oleracea hybrid breeding is the improved Ogura CMS. Currently the work on transfer of other CMS systems to B. oleracea is in progress and characterizing cytoplasmic sources employing mitochondrial markers is relevant to future studies on possible origins and molecular mechanisms of CMS in B. oleracea. Hence, in the present study cytoplasm sources of about 70 different CMS lines including CMS hybrids of cauliflower were analyzed using mitochondrial DNA-specific markers. All the CMS accessions contained the ogura specific ‘orf138’ related DNA fragment. However, polymorphic amplicons were also obtained in CMS accessions by two of the polymorphic mitochondrial primers. The mitochondrial markers identified here could be useful in detecting origin of CMS types during cauliflower breeding and further investigating mitochondrial-nuclear interactions leading to CMS in Brassica oleracea.

Abstract:

Statement of the Problem: Pastures often lack adequate nutrients to sustain livestock productivity. The lack of sufficient nutrients in rangelands could be due to the highly fibrous nature of pastures in semi-arid areas and anti-nutritional components found in these trees that might influence the diet and health of animals. Of concern is the high concentration of phenolic compounds, such as tannins in some browse products.

Purpose: The purpose of this study is to investigate the effect of landscape variations in chemical composition and in vitro ruminal degradability of Acacia nilotica and Maytenus heterophylla leaves harvested during dry season.

Methodology: Fresh leaves from twenty randomly selected individual trees, each from Acacia nilotica, and Maytenus heterophylla tree species, were harvested from the two sites by hand. Individual trees were selected from within a marked 100 × 100 m area each site. Factorial experiment in a completely randomised block design was used with landscape and tree species being the main factors, and with the 100 X 100 m plots within landscapes serving as blocks (replicates).

Findings: Leaves from Acacia nilotica had higher DM (dry matter), N (nitrogen) and CP (crude protein) in high landscape compared to those of Maytenus heterophylla. There was no significant difference on NDF (neutral detergent fiber) of leaves from A. nilotica on both high and low landscape while the leaves of M. heterophylla had high NDF in low landscape than high landscape. The two species revealed major variations in the macro element content in relation to landscape positions in both high landscape and low landscape areas. In the high landscape areas most of these elements had highest values for both species than those collected from the low landscape areas.

Conclusion & Significance: Plants from low landscape were deficient of macro-minerals Therefore; it is recommended that mineral supplements should be offered to animals to improve animal productivity throughout the year.

Abstract:

Sustainable drive toward achievement of food security and clean sanitation is an essential component of the Sustainable Development Goals (SDGs) agenda 2030. Continuous hazards posed by climate change stemming from carbon-dioxide (CO2) emission reverberated global endorsement to antagonize its negative implication with the best attainable firmness. Globally, Food Security face major challenges underneath climate change as a result of the potential negative consequences of agricultural production and unfair thoughtful implementation of sectoral actions in limiting greenhouse emission effects. The onus of this report stands to underpin existing literature by examining the causative nexus amidst agriculture production, economic growth and carbon dioxide emissions in selected sub-Sahara Africa emerging economies spanning 1991 to 2015. We meticulously, for the purpose of precision in our report disaggregated agriculture production into crops and livestock production to elucidate their uniqueness and also to pinpoint the precise involvement of the variable to carbon dioxide emissions. Empirical evidence by FMOLS and DOLS affirm that, 1% upsurge in crops production, deforestation and population, will aggravate a proportional growth in CO2 emission by 1.04%, 0.45%, and 0.39% harmoniously, alternatively, 1% boom in energy consumption, economy growth and livestock production will significantly ameliorate the environment of sub-Sahara emerging countries. The Pooled Mean Group (PMG) estimator was used to examine the direction of the variables in affirmation of their short-run and long-run dynamism. Our findings establish that, for the sub-Sahara emerging countries to obtain SDGs, it's a necessity to combat climate change, deforestation, hunger and poverty for their inhabitants. Regulation of farming production strategy and strict adaptation to agricultural era technique is a certainty toward SDGs 13, 15, 2 and 1 attainment.

Ian Levett is currently a PhD student looking into the development of novel controlled release agrichemical formulations using biodegradable polymers, predominantly using polyhydroxyalkanoates (PHAs). He obtained his integrated Bachelor’s and Master’s Degree in Chemical and Biological Engineering at The University of Queensland, Australia (2014).

Abstract:

Nitrogen (N) loss from agricultural land represents inefficiencies for the farmer and significant environmental impacts through N pollution of fresh and coastal waters, potent greenhouse gas emissions, and volatilization of other reactive N compounds. In Queensland, protecting our Great Barrier Reef (GBR) from nutrient dumping has environmental, social and economic benefits. More than 80,000 tonnes of N enters the GBR lagoon annually. Only 30-50% of N applied to sugarcane land in QLD is accounted for in crop biomass, with the balance lost to the environment. N stabilizing agents are commonly used in conjunction with N fertilizers to slow the biological oxidation of ammonium to nitrate in the soil. However, efficacy has only been proven for temperate climates. The persistence of nitrification inhibitors in agricultural soils diminishes rapidly with increasing temperature. Consequently, their use in tropical agriculture is limited. Dicyandiamide (DCD) has been studied as a fertiliser stabilizer for over 50 years for temperate and sub-tropical regions, however, efficacy is limited at elevated temperatures. The encapsulation and controlled release of DCD may prevent exposure of the molecule to degradation mechanisms until it is in the soil profile. Here, poly(3 hydroxybutyrate co 3 hydroxyvalerate) (PHBV) has been investigated as a biodegradable matrix for the encapsulation of DCD. Industrially relevant extrusion processing was used to fabricate DCD-PHBV pellets at a loading of 25 wt% DCD. Release profiles were monitored in water, sand and soil at 30°C. Release curves show significant surface wash (30-45%) within the first week, with a sustained release rate of 2.10 μg DCD pellet-1 day-1 from 3 weeks out to 20 weeks. After 20 weeks ~40-57% of the DCD was mobilized. We have demonstrated the ability to initially load the soil with a significant proportion of the encapsulated DCD, followed by a very gradual mobilization of the DCD into the soil.

Abstract:

Banana (Musa spp.) is a major fruit of India, which accounts for about 32% of the total fruit production. The ‘Nanjangud rasabale’ (NRB) is an elite native variety of banana originated from a place called ‘Nanjangud’ in Karnataka State. NRB with our survey it has been found that the area of cultivation of this Geographical Indicator banana variety has been shrinked from 10 to 4-5 Acre. It is popular and highly priced fruit in Karnataka and in other states because of its special qualities such as taste, aroma, color, fibrous texture and nutritional content. It has a triploid (AAB) genome and the hybrid origin belongs to Musa paradisiaca. The wilt of banana, caused by Fusarium oxysporum f.sp. cubense, is an important disease on Rasthali group (AAB) of banana. The assessment of genetic diversity of NRB and tracing back its origin of this elite genotypes is required for the rescue of this elite variety. Different types of molecular and biochemical markers will be used for evolutionary and population studies of banana. The DNA will be extracted at different stages of crop rise and these molecular markers are assayed. Same way different biochemical marker also be assayed at different stages of crop rise till physiological maturity of crop. Which provide number and physico-chemical properties of gene and its products. Simple sequence repeats (SSR) markers will be used and for biochemical marker isozymes of catalases, persoxidatse, super oxide dismutase, and NADP peroxidase are used. To revive this Geographical Indicator I have undertaken research for identifying the original variety of NRB and trace back its origin through above said marker. The protein polymorphism of banana reflects the genetic background and its interaction with environment therefore the crop will be sown at different location in Mysore and Hassan region. The expression of alleles coding for different isozymes are more or less independent from the environment; thus, this approach offers a relatively neutral means of determining genetic variation. The main reason of the limited use of isozymes could be the low level of polymorphism found in various plant kingdom. Plant descriptor for this plant type will be made with different morphological and biochemical content characters like carbohydrates, amino acids, proteins and some secondary metabolites will be assayed at different stages of crop rise.

Johannes Loubser is currently pursuing his PhD at Stellenbosch University, Republic of South Africa. and aims to further his research as a Postdoctoral Fellow at the same institution. He currently holds a Scarce Skills Doctoral Scholarship from the National Research Foundation (NRF) of Republic of South Africa. His research interests include growth promotion via the application of plant growth promoting substances (PGPS).

Abstract:

BC204, an agricultural product of a local company in Republic of South Africa, is a biostimulant consisting of a citrus extract and certain organic acids. The plant growth-promoting effect of BC204 has been demonstrated previously and is currently used in agriculture to promote plant growth in a variety of crops, increase yield and stimulate plants to improve resistance against abiotic and biotic stress. Although the physiological effects have been seen in practice, very little molecular or biochemical data has been collected. The aim of this study is to gain a deeper understanding of the biochemical and genetic changes occurring in Arabidopsis thaliana and Solanum lycopersicon following the application of BC204. Wild-type Arabidopsis (Col-0) plants were treated weekly with three different concentrations of BC204 or a water control for three weeks, after which the fresh weight, dry weight, leaf number, and leaf surface area were measured. The growth experiments were repeated using only the optimal BC204 concentration (0.01% v/v) and the same physiological measurements were recorded, with the addition of photosynthesis rates. Control and BC204-treated A. thaliana plants were harvested, RNA extracted and analysed for transcriptomic changes via an RNA-sequencing approach. Additionally, a hydroponic system was established for S. lycopersicon to analyze changes in root exudates via LC-MS following treatment with BC204. Furthermore, plants of both species were subjected to NaCl as a biotic stress and treated with BC204. Basic physiological measurements were recorded, as well as established osmotic stress markers. The expression of certain genes responsive to salt-stress were evaluated via RT-qPCR.
