摘要
针对半干旱区水分亏缺的实际田间环境,从渗透调节、光合作用、内源激素等方面探讨了水分亏缺下作物补偿效应的可能机制以及外界影响因素。同时,就补偿效应的普遍性对作物的抗旱生理以及遗传育种研究等问题提出了若干建议。
Crops drought resistance and its compensation effect are very complex ,its mechanism have not been understood in details.Therefore,based on the water deficit conditions in semiarid enviroment, mechanism of compensation effect and effect factors for crops from osmotic regulators,photosynthesis and endogenous hormone aspects are studied in this paper.Furthermore,some insights were presented on the research of crops deought resistance physiological and genetic breeding in according to popularity of compensation effect.
