摘要： 研究了2,-D,Na+A,PP333以及糖对怀山药微型块茎诱导形成的影响.结果表明:2,-D,Na+A单独使用时,诱导微型块茎形成的合适浓度均为0.5 mg/L,形成的微型块茎较多且较大;2,-D与Na+A组合中,Na+A0.5 mg/L+2,-D 0.5 mg/L所诱导的微型块茎较多且较大;Na+A为0.5 mg/L时,与PP333 0.1 mg/L的组合所诱导的微型块茎较多且较大,微型块茎形成率高达100%;蔗糖较白砂糖诱导形成的微型块茎多且大.

Abstract: This paper mainly deal with the effect of 2,4-D，NAA，PP333 and carbohydrate on the induction of bubils of Dioscorea opposita Thunb. The results show the more suitable concentration of NAA or 2,4-D was 0.5 mg，which could single induct more and bigger bubils; Among the combinations of growth regulations, NAA 0.5 mg/L+2, 4-D 0.5 mg/L can induct more and bigger bubils. When NAA being 0.5 mg/L,PP333 0.1 mgZ could induct more and bigger bubils. The inducting percent of bubils was 100%.Comparing sucrose and sugar, we finded that sucrose could induct more and bigger bubils than sugar.
