中文摘要：

以膜荚黄芪无菌苗子叶节为外植体，建立了简单、高效和稳定的膜荚黄芪再生体系。结果表明：不定芽诱导的最适培养基是Ms＋6-BA1．0nlg／L＋NAA0．10mg／L，每个子叶节外植体平均出芽数为3个以上，再生频率达75．5％；生根最适培养基为1／2Ms＋IBA0．5mg／L;移栽后成活率达75％以上。

英文摘要：

The cotyledon node obtained from aseptic seedling of Astragalus mend）ranaceus were used as the explant and a simple,stable and high efficient regeneration system for A. membranaceus were established. The results showed that the optimum medium for adventitious shoot regeneration was MS＋6-BA 1.0 mg/L＋NAA 0. 10 mg/L,the average number of differential buds per cotyledon node was above 3,and the regenerated frequency was 75.5% . The suitable rooting medium was 1/2MS＋IBA 0. 5 mg/L and the survive rate was above 75% after transplantation.
