6-BA动态效应对木薯单芽茎段的影响

Dynamic effect of 6-BA on cassava single bud stem

试验结果表明,6-BA对抑制木薯顶端优势很明显,浓度越高作用越显著。它不仅抑制木薯芽的径向生长,也抑制根的径向生长。但是适宜的浓度可以促使木薯腋芽萌发产生丛生芽。对于需要木薯植株快速成苗的情况,以不添加任何激素的MS基本培养基培养效果最好。

6-BA can obviously inhibit the growth of cassava seedling tips,which was more serious in higher concentration.The inhibition was on the growth of radial buds and roots.However,suitable content on medium could induce radial buds to form thickly growth buds.For seedling faster growth in cassava in vitro culture system,the MS media with no hormone was the best one.
