摘要：

摘要：以海南高种椰子胚培试管苗为移栽试材,研究了不同胚培苗质量﹑栽培基质、移栽环境对椰子胚培试管苗移栽成活率的影响。结果表明,椰子胚培苗移栽成活的关键在于胚培苗的质量，根系发达﹑生长健壮的胚培苗成活率高。正常苗﹑少根苗﹑污染苗的移栽成活率分别为86.7%﹑29.5%﹑36.4%。最理想的移栽基质为草炭：椰糠：河砂=2：1：1；在培养室环境下移栽效果最佳。

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.
