| 摘 要： | 在培养白桦试管苗的去分化阶段进行不同培养基、6BA浓度、蔗糖浓度对茎、叶去分化率影响的比较试验，结果表明：以MS＋NAA0．1mg／L＋IBA0．5mg／L为基本培养基时，茎、叶的去分化效果较好，并且添加的蔗糖浓度越低，越适于茎的分化，浓度较高，越适于叶的分化。

| Abstract: | During the dedifferentiational step of culturing the test-tube seedling of Betula Platyphylla Suk,we do some comparative experiments on effect of dedifferentiational rate on leaf and stem of different culture medium,6BA density,sucrose density.The result shows:When taking MS+NAA0.1mg/L+IBA0.5mg/L as basic culture medium,the the dedifferentiational effect of stem and leaf is better and the lower sucrose density added to,the more suitable to dedifferentiation of the stems;the higher density,the more suitable to dedifferentiation of leaves. |
