Callus was efficiently induced from in vitro root segment devoid of rhizodermis on MS medium.

结果表明，以离去皮根段，MS基本培养基，诱导愈伤组织较适宜。

The regeneration systems of “kuai shi” plum were established, using epicotyl and hypotyl as exophyte.

以快食李的上、下胚轴，建立了华李胚轴系，获得了株。

The result showed that the successful rooting system was closely related to the concentration of macronutrient of MS medium, auxin concentration and developing state of the explant.

结果表明，培养基中无机盐浓度、源激素水平、种类以及的发育状况等对试管嫩茎根具有明显影响。

It is the factors affected plant regeneration in explant culture in Euphorbia pulchrrima willd to different explants or aurin or cytokinin or the combination of the auxin and cytokinin.

的类型、物长素、细胞分裂素的类型及二者的不同组合均对一品红在离条件下株的具有影响。
