| 摘 要： | 根据前人的研究,植物激素对部分茎段剥皮后新皮再生有一定的影响。草本植物菊芋(Helianthus tuberosus L.)在正常情况下环剥后,其维管组织的分化过程与杜仲、茄子很不一样,对于一些外源激素的刺激反应可能也有差异,为此,有必要应用一些外源激素对菊芋环剥后再生新皮的组织分化进行试验研究。

| Abstract: | The stem of Jerusalem artichoke(Helianthus tuberosus L.)reacted variably when treated with IAA and BA after girdling.Formation of calli on the girdled surface of xylem was promoted but the production of periderm was retarded when it was treated with suitable con- centrations of IAA and BA.However,the comparatively high concentrations of IAA and BA also accelerated the differentiation of call into vascular tissues and eventually formation of new rind. |
