Not AvailableThe experiment with 39 sunflower genotypes screened by subjecting them to water stress in the laboratory by treating with PEG (poly ethylene glycol) solution at different concentrations viz., 0.0, -0.2, -0.4, -0.6, -0.8 MPa. root length, shoot length and seedling dry weight decreased with increase in osmotic stress. Increase in root length as a result of stress has also been observedNot Availabl

Not AvailableTrichoderma species are commonly used as bio-control agents against phytopathogenic fungi and some isolates are able to improve plant growth. In this study, effects of 9 Trichoderma strains in sunflower on photosynthesis, dry matter partitioning were examined. Plant height, number of leaves, days to 50% flowering, days to physiological maturity, Total Dry Matter, Photosynthetic Rate, SPAD Chlorophyll Meter Readings (SCMR), Leaf Area Index, Crop Growth Rate (CGR), Net Assimilation Rate (NAR), diameter of head, head weight, number of filled seed per head, 100 seed weight, seed yield and Harvest Index were studied by the application of Trichoderma strains.Not Availabl

Not AvailableRice (Oryza sativa L.) is a primary source of food for billions of people throughout the world, yet it contains insufficient levels of the key micronutrients iron, zinc and vitamin A to meet the daily dietary requirements. Biofortification of staple food crops has thus been considered a sustainable strategy to overcome the problem of micronutrient deficiencies prevalent in rice. The present investigation was conceptualized with the prime objective of mapping the chromosomal regions associated with high iron and zinc content involving the F2 populations derived from the cross of Swarna with Madhukar for high iron and zinc content using microsatellite markers derived from the genomic regions associated with iron and zinc metabolism. Three polymorphic markers viz., SC 120, SC 128 and SC129 were identified which were unlinked and hence single marker analysis was done to check the association of the marker with the trait. SC129 showed highest significant variation with both iron and zinc at the tune of R2=13.09% and R 2= 19.51%, respectively. The association could be made more stringent by further analysis of more number of lines and using more number of markers.Not Availabl
