果树对水分胁迫的生理响应

Physiological response of fruit tree on water stress

本文根据果树水分生理的研究进展 ,对水分胁迫下果树的光合作用、溶质积累与渗透调节、膜脂过氧化及活性氧伤害与防御、内源激素、氮代谢、矿质营养等生理响应进行了综述。提出了今后的重点研究方向。

On the basis of the advances of studies on water physiology of fruit tree,this paper reviewed the physiological response of photosynthesis,solute accumulation and osmotic adjustment,membrane lipid peroxidation,harmfullness and defence of active oxygen,endogenous hormones,nitrogen metabolism,mineral nutrition of fruit tree on water stress.The principle problems needed to be futher studied were also outlined.
