| 摘 要： | 探讨菘蓝花药处于单核晚期的形态指标，并以适宜发育时期的花药为外植体，进行花药培养及单倍体诱导。实验结果表明，4℃低温处理2d后，在含有6-BA0．5mg·L-1和NAA1．0mg·L-1。的Ms培养基上，花药愈伤组织的诱导率为23．35％；将其转接到Ms附加6．BA1．0mg·L-1，NAA0．5mg·L-1的分化培养基上，80．00％以上的愈伤组织可以诱导产生不定芽；再将分化出的试管苗转接到1／2MS＋NAA1．0mg·L-1的生根培养基上，3d左右即可获得完整植株。经叶边缘压片检查染色体数目，花药培养所得的弱小绿苗为单倍体植株。

| Abstract: | Anther culture and haploid induction were carried out from Isatis indigotica. The experimental results showed that cold pretreatment could increase the induction rate of callus. The induction rate of callus was 23.35% after 2 days of cold pretreatment. Then the calluses were successively transferred to differentiation medium （ MS＋BA 0.5 mg· L-1 ＋ NAA 1.0 mg · L -1 ） and rooting medium （ 1/2MS＋NAA 1.0 mg · L-1 ）. The complete plants were obtained 3 days later. Among which, those weak and green plantlets were haploids with 7 chromosomes. |
