报道了菘蓝外植体（子叶、下胚轴、叶和胚根）在不同激素条件下直接分化成苗，再生植株的研究结果。外植体分化芽需要有BA和NAA的适宜配合；单独用NAA或IBA有利于芽的生根，并长成完整植株。

Budgenesis of Isatis indigoica Fort. was observed on MS medium with BA and NAA from cotyledon,hypocotyl,young leaf and radicle. Rootgenesis of the bud was stimulated by NAA or IBA added to the MSmedium,and eventually grow into a complete plantlet.
