This experiment was conducted in two successive seasons (2012/13 & 2013/14). Under the condition of
plastic house covered with seran. The objective was to study the effect of seed husk, GA3, KNO3 and seed orientation in
seedbed on germination percentage and subsequent seedling growth of White Succary rootstock. From this study, the
highest germination percentage and germination velocity of mango seeds and standard seedling growth could be
achieved through husking seeds or sowing seed in position of vertical with the convex edge upwards after soaking in tap
water (48h) or through soaking seeds in GA3 at 1000 ppm for 48h.Moreover, there was a remarkable effect of husking,
GA3 and KNO3 in increasing growth of the obtained seedlings in terms of stem length and leaf number as well as the
fresh and dry weights of roots.
