植物抗寒生理性研究进展

Research Progress on Cold Resistance Physiology of Plant

结合低温胁迫过程中相关生理指标的变化,对植物的抗寒性强弱进行了探讨,从而为植物的引种栽培提供参考依据,更为耐寒植物品种的选育奠定基础。通过对目前植物抗寒生理性研究的分析发现,目前广泛采用依据自然降温或人工设置低温胁迫过程中相关生理生化指标的变化,对植物抗寒性进行判断;并对2种方式中分别存在的研究周期长、较难真实模拟自然界低温等特点进行了初步探讨;尤其针对植物的抗寒性易受到环境温度的变化而发生改变的现实,对目前抗寒性研究中依然少见有对降温幅度、持续时间等对植物抗寒性影响的综合性研究进行了展望。

Combined with the physiological changes in the low temperature stress process, the cold resistance of plant has been explored .which would provide a reference for the introduction and cultivation of plant .rneanwhile for the breeding of cold resistance plant varieties. Through analysis of study on the cold resistance of plant .it found that the cold resistance of plant was usually determined according to the changes of physiological and biochemical indicators in the natural cooling process or artificial low temperature stress. The characteristics of these two methods were investigated .and it found that they existed some problems including research cycle longvrnore difficult to simulate the natural low temperature and so on. Especially for the actual situation, that plant could hardiness was easily affected by temperature changes, the temperature drop range and duration effect on the cold resistance of plant has rarely been studied.
