水淹胁迫对植物光合生理生态的影响

Effect of Waterlogging on Photosynthetic and Physioecological Characteristics of Plants

水淹胁迫是河岸带和湿地植被遭受的常见逆境因子之一。植物为适应水淹环境会产生一系列复杂的生理代谢变化,这些变化对植物能否在水淹胁迫下具有正常的生理功能和进行生长发育至关重要。文中总结和评述了水淹胁迫下植物生理代谢的变化,包括植物光合生理(气体交换参数、光合色素、叶绿素荧光参数)和其他生理代谢(丙二醛、抗氧化酶系和根系碳水化合物)等变化,分析了目前研究中存在的问题,并提出展望。

Waterlogging stress is one of the most common stress factors to which plants in the riparian zone and wetlands are subject. Plants will produce a series of complex physiological and metabolic changes to adapt to flooding environment. These changes are essential to whether plants can adapt to waterlogging stress and then develop the normal physiological function and growth. In this paper, we systematically studied and reviewed the physiological and metabolic changes of plants under waterlogging stress, including the changes in photosynthetic physiology such as gas exchange, photosynthetic pigment and chlorophyll fluorescence, and in malondialdehyde like antioxidant enzyme system and root carbohydrate. Finally, we analyzed the existing problem in current studies and prospected the future research direction.
