摘　　要：植物在干旱胁迫下的生理代谢变化一直是抗旱生理的研究热点。植物为适应和抵御干旱环境所形成的形态特征和生理特性以及生理变化机制是一个复杂的系统。通过对部分抗旱生理生化研究进展的归纳和总结,主要从3个方面提出植物在干旱胁迫下的主要生理反应和生化变化指标。并通过比较分析,综述了在干旱胁迫下植物生理生化方面的反应和变化规律。从而为抗旱种质的鉴定、筛选和抗旱生理育种提供参考。The plant drought-resistant physiology breeding,its essence is applies the plant-physiology principle and the method in the drought-resistant breeding.Plant＇s under arid coercion physiological metabolism change always is the drought-resistant physiology research hot spot.Plant the shape characteristic and the physiological characteristic as well as the physiological change mechanism which forms for a long time for the adaptation and the resistance arid environment is a complex system.This article through the induction and the summary which progresses to the part drought-resistant physiology biochemistry research,proposed plant＇s under arid coercion main physiological reaction and the biochemistry change target from three aspects.（1） The maintenance moisture content metabolism 3 physiological essential factor,namely blowhole resistance,root system vigor and photosynthesis speed.（2） The maintains in vivo cell water content the seepage adjustment material proline accumulation tendency.（3） The maintenance adult plant in vivo active oxygen ion metabolism is balanced,defends the active oxygen to accumulate,protects the cell not 3 protection enzyme active change which injures.And through the comparative analysis,summarized under the arid coercion the plant in the above three physiological biochemistry aspect response and the change rule.Thus for the drought-resistant idioplasm appraisal,screening and the drought-resistant physiology breeding provided the reference.
