Adventitious rooting of Begonia semperflorens cv. Indian Maid and Vitis vinifera cv. Semillon stem cuttings was significantly promoted by human chorionic gonadotropin (HCG). Basal sections of HCG treated cuttings upon which promoted rooting took place had markedly less endogenous gibberellin (GA) activity than non-treated controls or apical sections of treated ones, while changes in auxin levels were not found. HCG also inhibited GA(3)-induced reducing sugar release from embryoless barley endosperm halves. These findings are discussed in the light of a possible analogy to gonadotropin action in animal systems.
人绒毛膜促性腺激素（HCG）显著促进了四季秋海棠品种印度女仆和酿酒葡萄品种赛美蓉茎插条的不定根形成。HCG处理的插条基部切段发生了生根促进现象，与未处理的对照或处理插条的顶端切段相比，其内源赤霉素（GA）活性明显较低，而生长素水平未发现变化。HCG还抑制了GA(3)诱导的无胚大麦胚乳半粒还原糖释放。根据与动物系统中促性腺激素作用的可能类比来讨论这些发现。
