| 摘 要： | 采用改进的籽粒离体培养系统对糖分浓度、GA3、ABA以及乙烯对籽粒发育的调控进行了研究，结果表明：有机营养供应状况与籽粒发育密切相关；相对较高的ABA／GA3利于籽粒的正常发育；籽粒发育的前期是对乙烯的敏感期。激素对籽粒发育的调节可能以可溶性酸生蔗糖转化酶为调节位点。

| Abstract: | Effects of sucrose? GA 3? ABA and ethylene on the development of maize kernels during the early stage of kernel development were studied using a revised in vitro culture system. Sucrose supply has close relationships with kernel development; a relatively high ABA/GA 3 rate favors to kernel development; kernels at the early developing stage are very sensitive to ethylene. The regulation of hormone on kernel development may be mediated by soluble acid invertase. |
