油菜的每一叶腋里都有一个腋芽,在条件适宜时,腋芽节间伸长形成分枝,分枝的叶腋里可以再分生分枝。油菜在大田生产条件下抽出的分枝已进入生殖生长阶段,不宜在繁殖中利用。本文报道在不满足油菜花芽分化所需要的温度条件下,利用植物激素促使腋生分生组织迅速生长形成腋生枝,快速繁殖油菜的方法,并描述试管苗的性状。 Each leaf rape axillary buds have an axillary bud, when conditions are appropriate, the axillary buds grow internodes to form branches, branching leaf axils can be further branches. Rape branches in the field under the conditions of production has entered the reproductive growth stage, should not be used in breeding. In this paper, we report the rapid growth of axillary meristematic tissue to form axillary branches and rapid propagation of rape using phytohormones under the conditions that do not meet the needs of rape flower bud differentiation, and describe the traits of tube seedlings.
