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 hypoxia and low light conditions caused by the flooding environment make the morphological, physiological and metabolic changes of plants to varying degrees. Plants change their growth traits through these changes to adapt to flooded environments. Photosynthesis is one of the important physiological characteristics of plants. Its response to stress conditions has become an effective indicator of stress tolerance in plants. The paper summarizes a series of photosynthetic adaptive mechanisms formed by plants during flooding, including the regulation of photosynthesis, the regulation of photorespiratory energy consumption and the protection of antioxidant system. The operation of these mechanisms to some extent regulate the photosynthesis process, protect the photosynthetic organs, thus maintaining the growth of plants.
