Abstract

Pre-harvest sprays of CaCl2 (0.1, 0.5 and 1.0%), BA (10, 20 and 30 ppm) and GA3 (50, 100 and 150 ppm) were given on capitulum of sunflower cv. Morden at 60, 70 and 80 days after sowing (DAS). Application of GA3 (100 ppm) especially, at 60 DAS and storage of achenes, particularly in poly pack was more effective in maintaining seed quality in terms of seedling vigour index (SVI) in sunflower.
