摘    要:以番木瓜(穗中红-48)漏斗型体细胞胚胎为材料,探讨体细胞胚胎发育及植株再生的适宜条件.研究结果表明,附加2%椰乳、0.1mg/LABA及40g/L蔗糖的Ms固体培养基较适合番木瓜漏斗型胚状体的发育及成熟.充分成熟的子叶型胚状体在大量元素减半、蔗糖含量30g/L的Ms培养基上,配合1500lx光照可再生健康小植株,再生率为78%.

关 键 词:番木瓜  体细胞胚胎  发育  再生

Abstract:The optimum conditions for the development of somatic embryogenesis and plantlet regeneration of Carica papal cv. Suizhonghong-48 was studied. The results showed that MS medium added with 2% coconut milk, ABA at 0. 1 mg/L and sucrose at 40 g/L was suitable for the development and maturity of funnel-shaped embryoids of C. papaya. The healthy plantlets were regenerated from the fully mature cotyledonous embryoids on adjusted MS medium (half strength of microelements) containing sucrose at 30 g/L and 1500 1x of illumination. The regeneration rate was 78%.
Keywords:Carica papaya somatic embryogensis  development  regeneration
