外植体

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

结果表明，以离去皮根段为外，MS为本，诱导愈伤组织较为适宜。

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

以快食李的上、下胚轴为外，建立了三华李胚轴再，获得了再株。

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，中无机盐浓度、外源激素水平、种类以及外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.

外的类型、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再具有影响。
