摘　　要：对影响大白菜小孢子培养供试材料的不同生长环境和取蕾时间2个因素进行了研究,结果表明,耐热夏大白菜品种在高温下容易诱导出胚,不耐热秋大白菜品种在较低温度下容易诱导出胚;下午取蕾的胚诱导率高于上午取蕾,大白菜小孢子培养胚适宜取蕾时间应选择在下午。The results of studies on effects of different growth environment of tested materials and times of bud cutting on microspore culture in Chinese cabbage showthat embryo induction is easy under high temperature condition in summer Chinese cabbage varieties and under lower temperature condition in autumn varieties.Suitable time of bud cutting should be choosen in the afternoon because induction rates of embryos are higher in the afternoon than in the morning.
