园艺植物高温逆境生理研究进展

Research Progress in High Temperature Stress Physiology of Horticultural Plants

探讨了茶树高温逆境中的生理指标,揭示低温冷害对茶树生长发育和光合作用等方面的影响。选择茶树进行高温逆境生理响应实验,通过模拟茶叶栽培过程中所遭受各种不利条件(光照强度和土壤含水量变化)。结果表明:随着温度升高、光照强度增强及茶树叶片叶绿素含量显著增加而影响茶树生长发育;冷害会影响茶树的光合作用,且会限制茶树的正常生长发育,从而影响茶树对低温环境中物质代谢和结构的调控。

To explore the physiological indicators of tea plants under high temperature stress,and reveal the effects of low temperature and chilling injury on the growth,development,and photosynthesis of tea plants.A physiological response experiment was conducted on tea plants under high temperature stress to simulate various adverse conditions(changes in light intensity and soil water content)encountered during tea cultivation.The results showed that the growth and development of tea plants were affected by increasing temperature,increasing light intensity,and significantly increasing chlorophyll content in tea leaves.Cold injury can affect the photosynthesis of tea plants and limit their normal growth and development,thereby affecting the regulation of material metabolism and structure in low temperature environments.
