摘要:水淹环境造成的低氧和低光照条件使植物的形态、生理和代谢发生不同程度的变化。植物通过这些变化改变自身生长特性,以适应水淹环境。光合作用是植物重要生理特性之一,它在胁迫环境下的响应变化已成为反应植物耐胁迫能力的有效指标。文中总结了水淹过程中植物形成的一系列光合适应性机制,主要包括光合作用进程调控、光呼吸能耗调节和抗氧化系统保护。这些机制的运行在一定程度上调节了光合作用进程,保护了光合器官,从而维持了植物的生长。
The condition of low oxygen and low illumination created by the flooding environment causes different changes of plants in shape,physiology and metabolism.Plants also change their own growth characteristic in order to adapt to the flooding environment.Photosynthesis is one of the important physiological characteristics of plants.Its change in response to stress environment has become an effective index to reflect plant stress tolerance capacity.This paper summarized a series of adaptive mechanisms of photosynthesis formed in plants during flooding,including: 1) photosynthesis process control;2) photorespiration energy regulation;and 3) antioxidant protective system.The running of these mechanisms regulates to some extent the photosynthesis process,protects the photosynthetic organ,and finally maintains the growth of plants.
