光敏色素：在大多数植物器官，特别是在分生组织和黄花苗中低浓度存在的蛋白色素。

Segments produced clusters of somatic embryos from embryogenic calli or directly from root apical meristems , and that also can convert into bud directly in the different tissue culture conditions. Modified media B5 with 1.0 mg.L-1 2,4 - D and 3.0mg.L~1 6-BA is suit to induce calli, and 0.5 mg.L-1 NAA is fit for somatic embryos inducement from calli. 6-BA encreased direct somatic embryogenesis on root tip distinctly,but NAA is retard it. NAA also prolong the time of root-tip convert into bud directly.

在改良B_5(微量元素为原来的1／3)中加入1.0mg.L~(-1)2，4—D和3.0mg.L~(-1)6-BA对离体根尖的愈伤组织诱导较为合适，0.5mg.L~(-1)NAA有利于从愈伤组织上产生体细胞胚；6-BA明显促进离体根尖直接产生类原球茎，而NAA则有阻碍作用；同时NAA的存在也使离体根尖直接成芽的时间延长。
