Abstract
以吊钟花(Enkianthus quinqueflorus Lour.)茎尖及带腋芽的茎段为外植体进行组织培养.结果表明,改良B5培养基(B5大量元素和钙盐+MS有机物、铁盐、微量元素)最有利于吊钟花的培养,外植体在改良B5+2,4D- 1 mg L-1的培养基中,愈伤组织诱导率可达100%.在含BA 1~2 m L-1+NAA0.1~0.5 mg L-1培养基中,可诱导产生不定芽.继代培养以改良B5+BA 1 mg L-1+NAA0.5 mg L-1培养基的增殖系数最高.生根培养基以1/2MS+IBA2 mg L-1为最佳,生根率可达80%以上.试管苗移栽成活率为90%以上.
