Abstract:

Abstract:The embryogenic test tube seedlings of Hainan tall coconut were used as transplanting materials and the effects of quality of embryogenic test tube seedling,cultivation substratum, transplanting condition on the survival rate were studied. The result showed that the quality of seedling was the critical factor for transplant survival rate. The seedlings with developed root system and strong growth has high survival rate. The survival rates of normal transplant, less roots transplant and contaminated transplant were 86.7%, 29.5%, 36.4%, respectively. The optimal medium for transplant was the combination of grass peat, coconut fibre bit and river sand in proportion as 2：1：1, while the optimal place for transplant was culture room.
