【摘要】 龙牙蕉吸芽茎尖经MS+6-BA 5.0 mg/L+AD 20 mg/L培养基诱导出不定芽后,在MS+BA 4 mg/L+NAA 0.1 mg/L培养基上继代培养对不定芽的分化较好,平均分化倍数为2.6倍以上,无根小苗在1/2 MS+NAA 0.5 mg/L+AC 1 g/L培养基上进行生根培养,1周后长出新根。组培小苗移栽假植成活率94%,大田栽培表现正常。更多还原

【Abstract】 Adventitious buds were induced from shoot-tip explants of Musa spp Longyajiao in MS+6-BA5.0 mg/L+AD 20 mg/L.The multiplication medium with MS+BA 4 mg/L+NAA 0.1 mg/L was better for the buds growth and the average multiplication rate was over 2.6 times.Plantlets were cultured on 1/2 MS+NAA 0.5 mg/L+AC 1 g/L,for rooting culture,after 7 days the roots of the plantlets were developed.The regenerated plantlets were transplanted to soil,and the survival rat of transplanting reached 94%.The plants grew well in the field.更多还原
