摘要
研究了以盐桦的带芽茎段为外植体诱导丛生芽及植株再生的过程，并筛选出其最佳分化增殖培养基为MS＋6-BA0．5mg·L^-1＋NAA0．62mg·L^-1＋蔗糖3．0％十琼脂0．6％。经过4～6周的培养，其增殖系数为5．8；最佳生根培养基为1/2MS＋IBA0．3mg·L^-1＋蔗糖0．15％＋琼脂0．6％，生根率为100％，平均根数5．7条。
In this article Betula halophila＇ s stem with buds part for explants lead to bunch buds and plant regeneration process were researched, and among them the best increment culture medium that it was MS ＋ 6-BA 0.5mg/L＋ NAA 0.02mg/L ＋ sugar 3.0% ＋ agar 0.6% were selected out , through culture 4-6 weeks, the best increment multiple was 5.8 , the best rooting culture medium was1/2MS ＋ IBA0.3mg/L ＋ sugar 0.15% ＋ agar 0.6%, the rooting rate was 100%, and the single ste m＇sroots were 5.7 .
