Effect of Growth Regulators on Seed Germination and Seedling Growth of Sapota

Y. Pampanna, G.S. Sulikeri

Abstract


The study conducted to know the effect of pre-soaking of sapota seeds in growth regulators on seed germination and growth or seedling revealed that, per-soaking of seeds in GA+ethrel each at 400 ppm  resulted in the higher (90%) and early (12.15 days) germination and also recorded the highest emergence rate index (21.95) and Bartlett ‘s rate index(0.642). Seedlings raised from the seeds pre- soaked in GA 400ppm produoed significantly higher shoot length (10.65 cm) and the highest root length (6.73 cm). The number of  leaves per seedling was maximum (6.75) and the setting vigour Index was highest (1 416) with GA+ ethrel each at 400 ppm pre-soaked seeds.
