水分利用效率及其生理生态机理研究进展

Research progression on water use efficiency and its physio-ecological mechanism

摘要: 系统分析了水分利用效率理论及其与作物产量的关系,并从作物生长发育、光合与蒸腾作用、水分状况以及空气相对湿度等环境因子诸方面对水分利用效率的生理生态机理研究进展进行了探讨。

Abstract: The theory of water use efficiency(WUE)and the correlations between WUE and crop yield are analyzed．The researches of WUE physio-ecologieal mechanism in recent years on plant growth and development，photosynthesis and transpiration，water condition，other environmental factors such as air relative humidity,and so on are introduced．
