Abstract:
A study on herbal molecules infused nano-fibre seed coating for extending the storability of accelerated aged black gram seeds at the Department of Seed Science and Technology, TNAU, Coimbatore was undertaken during 2022. The nano-fibre developed from zein (20%) was infused with curcumin and azadirachtin. Zein nano-fibre matrix was applied to genetically pure black gram cv.VBN 8 seeds at various concentrations viz., 5, 10, 15, 20, 25, 30, 35, 40, and 45 ml per kg of seeds. The treated seedlings underwent 10 days of accelerated aging at temperature 40 ⁰C and relative humidity of 98±2%. The seed samples of 50-100g were taken each day during the accelerated aging process and analyzed for physiological parameters. In terms of germination (77 percent), root (14.3 cm) and shoot length (15.3 cm), and seedling vigour index I (2202) and II (22), the seeds revitalized with zein nanofiber matrix at 20 ml per kg of seeds considerably outperformed the control seeds. The results of this study revealed that, despite the accelerated aging process, black gram seeds infused with zein nanofiber matrix at 20 ml per kg of seeds outperformed other treatments.
