不同激素和环境胁迫调控水稻分蘖的研究进展

摘要

分蘖的生长发育除了受自身遗传因素的调控外,还受激素和外界环境非生物因子的调控.为了明确水稻分蘖生长发育的调控机制,综述了生长素、细胞分裂素、独脚金内酯、油菜素内酯、氮素、旱涝、冷热等因素对水稻分蘖的影响,并讨论了目前分蘖研究中存在的问题和展望,以期为分蘖调控机制的研究和分子栽培调控提供理论参考.%Tiller growth and development are regulated by tiller-related genes as well as hormones and environmental stresses.In order to understand the molecular mechanism of regulation on tiller growth and development, the effects of auxin, cytokinin, strigolactone, brassinolide, nitrogen, drought or flood, heat and cold on rice tillering were summarized below, and some related problems and prospect were analyzed, so as to provide theoretical insights for research on tiller regulation and molecular cultivation.
