摘要:

内源激素对作物高效用水有重要调控作用。此文系统论述了内源激素对作物高效用水的调控作用和机理,从水分利用效率的内涵、内源激素与作物叶片水平水分利用效率(WUEl)、内源激素与生物量水平的水分利用效率(WUEbm)、产量水平水分利用效率(WUEy)的关系等方面综述了国内外内源激素与高效用水的关系研究进展。在此基础上,提出了激素对作物高效用水调控研究中存在的问题,并探讨了今后的研究发展方向。

Abstract:

Regulation mechanism of endogenous hormone is of great importance for efficient water use of crops.In this paper, firstly, necessity and importance of further study on regulation mechanism of endogenous hormones for water use efficiency was dissertated, and then research progresses at home and abroad were reviewed including relationship between endogenous hormone and water use efficience in leaf level, between endogenous hormone and water use efficiency in biomass level and between endogenous hormone and water use efficiency in yield level of crops. Based on the research progresses, some problems and controversies in the research field were put forward, and future research trends of endogenous hormone in water use efficiency were discussed.
