| 摘 要： | 以花椰菜的花托、花序轴和未受了房为外植体，诱导出不定芽，并进行继代增殖培养，在工增殖培养基上每隔２５～３０天，不定芽可以增殖５～６倍，不加激素的１／２ＭＳ培养基上，试管苗生根率达到９８％以上，移栽成活率达到９５％以上。经观察，花托和未受精了再生植株是由外植体直接分化而来，不经过愈伤组织阶段，这样可避免不良变异，保持材料的遗传稳定性。

| Abstract: | Receptacle,rachis and unfertilized ovary of cauliflower were as explant for inducing plant regeneration and subcultured.Subcultured shoots on Ms 199 medium could be increased to 5-6 times in every 25-30 days.Rooting rate reached more than 98% on 1/2 Ms medium without any hormone.The surviving rate of the plantets transfered into soil reached more than 95%.Throngh abservation,We found that the plantlets came directly from receptacle and unfertilized ovary explants without callus stage,thus can avoid bad variation and keep genetic stability of culture materials. |
