花生对水分胁迫的响应研究进展

Research progress of the effects of water stress on peanut

花生是我国主要的油料作物和重要的经济作物,干旱对其生长发育、代谢生理、产量、品质及水分利用效率均有一定的影响。本文分析了水分胁迫及复水后,花生生长、代谢生理的调节动态;总结了花生品质的变化规律;综述了花生水分利用效率因其受水分胁迫及复水后的响应,水分胁迫及复水对花生生长、代谢生理、产量、品质及水分利用效率的影响,为进一步实施花生的节水栽培技术和确定花生的调亏灌溉制度提供参考。

Peanut is a major oil crop and an important economical crop in China. Drought is one of the most important environmental stresses affecting the productivity and quality of peanut. The paper analyzed the regulation dynamics of peanut growth and metabolic physiology,concluded the changes of peanut quality,and summarized the response of peanut water use efficiency to water stress and re-water. Elucidation of the complex mechanism will provide a theoretical basis for further implement of peanut water-saving cultivation techniques and choice of peanut deficit irrigation regime.
