| 摘 要： | 报道了在甘蔗幼苗分化培养基中添加不同浓度配比的外源激素对绿苗分化及内源激素的影响。结果表明:外源激素对分化苗中的内源激素有促进或抑制作用,外源激素的添加对IAA,GA1＋3产生不同程度的抑制作用,其中高比例的生长素/细胞分裂素对分化苗中的IAA抑制作用强,对GA1＋3的抑制作用弱,而外源激素的添加对CTK产生促进作用,其中低比例的生长素/细胞分裂素对细胞分裂素的促进作用强。同时,在甘蔗愈伤组织分化幼苗过程中,合适配比及水平的外源激素添加有利于幼苗分化。

| Abstract: | Study on the effects of exogenous hormones on shoot differentiation and endogenous hormones in the course of differentiation of sugarcane in this paper. It was showed that the exogenous hormones can advance or inhibit the endogenous hormones of differentiation shoots. The compound of IAA and GA 1+3 can be inhibited in some level by adding the exogenous hormones to the media. The higher ratio of NAA/BA had the powerful inhibit for the IAA and weak inhibit to GA 1+3 , but the exogenous hormones can advance the synthesis of CTK, and the lower ration of NAA/BA had the powerful advance to the synthesis of CTK. At the same time, it is advantageous to the shoot differentiation by adding exogenous hormones suitable with suitable ratio and level in the course of callus differentiation. |
