Abstract : Osmopriming treatments such as soaking of mango stones (extracted from fruits collected in Bangalore, Karnataka, India) for 12 h in gibberellic acid (GA3; 100, 200 and 300 ppm), potassium nitrate (1, 2 and 3%) and water increased the germination percentage and enhanced the rate of germination of mango stones. GA3 at 200 ppm for 12 h was the best treatment which recorded the maximum germination percentage (85.5%) compared to other osmopriming treatments. All the osmopriming treatments increased the seedling characters and seedling vigour. GA3 at 200 ppm recorded the maximum seedling growth and GA3 at 100 ppm recorded the maximum seedling vigour (3390.4) compared to other osmopriming treatments. Significant correlations were observed between the germination percentage, seedling growth and seedling vigour of mango stones.
