不同激素对谷子幼穗组培的作用不同。2，4－D主要是诱导愈伤组织，KT主要是促进细胞分裂。2，4－D2mg／L与KT0．2mg／L配合为最佳诱导培养基。6－BA对分化成苗起主导作用，分化率随着6－BA浓度加大而提高。6－BA2mg／L与NAA0．2mg／L是最佳分化培养基，分化率最高达60％。LAA与NAA主要是促进长根。1／2MS比1／2MS＋NAA0.2mg／L分化出的根白、嫩、多，且移栽成活率高。
Different hormones have different effects on tissue culture of young ears of millet. 2,4-D is mainly induced callus, KT is mainly to promote cell division. 2,4-D2mg / L and KT0.2mg / L with the best induction medium. 6-BA played a leading role in differentiation, and the differentiation rate increased with the increase of 6-BA concentration. 6-BA2mg / L and NAA0.2mg / L is the best differentiation medium, the highest differentiation rate of 60%. LAA and NAA mainly promote long roots. 1 / 2MS than 1 / 2MS + NAA0.2mg / L differentiation of the root white, tender, and more, and high survival rate of transplanting.
