| 摘 要： | 通过建立组织培养快繁体系,探讨KT和NAA对膜荚黄芪茎段诱导生成新生茎、愈伤组织及生根的影响。KT/NAA值为4时,对茎的诱导作用明显,获得最多的茎平均数(11.7条)。NAA促进愈伤组织形成,在1 mg/L NAA作用下最大的平均直径为1.4 cm,多为白色。根生于白色愈伤组织,并受NAA促进、KT抑制。1 mg/L NAA对根数、根长和次级根数均有促进作用,但对根粗有抑制作用。

| Abstract: | Through the establishment of tissue culture rapid propagation system,the effects of KT and NAA on the induction of new stem,callus and roots of Astragalus membranceus were studied.The induction of new stem was related to the ratio of KT/NAA,which was obvious with the average number of new stem was the maximum,11.7,when the value was 4.With the promotion of NAA,lots of white callus was produced.The average diameter of white callus,which was in the medium with 1mg/L of NAA,was 1.4 cm.Roots came mainly from th... |
