激素间相互作用对植物茎伸长生长的调控综述

Hormonal Interactions in the Control of Plant Stem Elongation

植物茎的伸长受多种内外因素的调节和控制,其中内部的内源植物激素如赤霉素、生长素等的调控起重要作用,且内源激素不但通过内源激素水平调控,而且还通过激素间的相互作用调节和控制茎的伸长。笔者介绍了各种内源植物激素(如生长素与赤霉素、生长素与油菜素内酯,赤霉素与油菜素内酯,生长素与乙烯等)之间的相互作用调控植物茎的伸长生长的研究概况。

Plant stem elongation is regulated and controlled by a lot of exogenous and endogenous factors. One of endogenous factors is plant hormonal, for example gibberellin （GA）, auxin et al, which is important to promoted stem elongation. Plant stem elongation is dominated not only by the level of hormonal but also by hormonal interactions. Surveys and advances in research on hormonal interactions were summarized in this paper, for example, auxin （Indole-3-acetic acid, IAA） and GA, auxin and brassinosteroid （BR）, GA and BR, auxin and ethylene （ETH）, in the control of plant stem elongation.
