热胁迫对10个水稻品种生理生化特性的影响
Effects of Heat Stress on Physiological and Biochemical Characteristics in 10 Rice Varieties
摘要
Abstract
To explore the effects of heat stress on photosynthetic characteristics and physiological indexes of rice,taking 10 rice varieties as materials,the activities of superoxide dismutase (SOD),peroxidase (POD),methane dicarboxylic aldehyde (MDA),net photosynthetic rate and chlorophyll content were determined.The results showed that the SOD and POD activities and the MDA content increased with the extension of stress time.The activity of SOD increased the most,and the content of MDA increased the fewest in D You 3138.The net photosynthetic rate and chlorophyll content gradually decreased with the extension of stress time.The net photosynthetic rate and chlorophyll content in D You 3138 were higher.The comprehensive physiological indexes and phenotypic characterization after heat stress showed that D You 3138 had stronger heat resistance at seedling stage.关键词
