Executive Summary : | The study aims to understand the role of melatonin in regulating seed yield and lipid composition in salinity-stressed sunflower cultivars. Sunflower, a major oil seed crop, is ranked second in the world after soybean. It provides a high oil content and protein content, but faces systemic weather risks due to scant rainfall. Sunflower is moderately tolerant to salinity stress, with NaCl concentrations of 40-80 mM causing no significant effects. Most attempts have focused on seedling growth and antioxidative defense in the vegetative stage, but more research is needed to demonstrate the effect of these priming molecules on seed yield, average achene weight, and lipid composition. Despite reports of melatonin in various plant systems, no significant work has been performed to understand its role in seedling establishment, plant growth, seed yield, and analysis of seed lipid content in NaCl sensitive and tolerant sunflower cultivars. The proposed work aims to assess the potential role of melatonin in regulating physiological and biochemical parameters associated with seed development, seed yield, and seed lipid content in salt-sensitive and salt-tolerant genotypes of sunflower cultivars in West Bengal. Melatonin and boron co-application during the reproductive stage is likely to improve B utilization efficiency, promoting seed yield. |
