Physiological Mechanisms of Photosynthesis and Antioxidant System in Rice under High Temperature Stress

Rice (Oryza sativa), as one of the major global food crops, faces threats to its growth and yield due to climate change, particularly high-temperature stress. This study aims to delve into the physiological mechanisms of rice photosynthesis and antioxidant systems under high-temperature stress conditions. The objective is to analyze how rice responds to high-temperature pressure and understand its adaptive mechanisms. By synthesizing and analyzing data related to rice photosynthesis and antioxidant systems under high-temperature stress, the study summarizes the physiological responses of rice to high temperature, including the adverse impacts on growth and yield, as well as changes in relevant physiological parameters. Furthermore, the study discusses the regulation of photosynthesis and the mechanisms of the antioxidant system under high-temperature conditions, with particular emphasis on the variations in antioxidant enzyme activities and the importance of antioxidant substances in protecting plants from oxidative damage. The significance of this research lies in enhancing our understanding of the adaptability of rice to climate change, providing crucial insights for improving rice resistance to high-temperature stress.
