高温胁迫对番茄光合影响及缓解机制研究进展

Research Status on the Influence of High Temperature Stress on Photosynthetic System of Tomato and Mitigating Mechanism

高温胁迫是制约我国番茄产量的主要因素之一,而光合作用是番茄产量形成的基础。因此,研究高温胁迫对光合作用的影响及缓解机制,对提高番茄产量和品质有重要意义。概述了高温对番茄光合系统的气孔、光合色素、光反应和暗反应的影响。分别从自身保护机制、外源物质和环境因子的调节作用,阐述了番茄高温胁迫缓解机制的研究进展。在此基础上,提出了高温对番茄光合影响和缓解机制中还存在的问题,为后续研究提供思路和方向。

High temperature stress was one of the main factors restricting yield of tomato,whereas photosynthesis was basic to production of tomato.Therefore,it was of great significance to study the influence of high temperature stress on photosynthesis and its alleviation mechanism,in order to improve the yield and quality of tomato.It summarized the influence of high temperature stress on photosynthesis of tomato from the perspectives of stomata of leaf,photosynthetic?pigments,light-dependent reactions and light-independent reactions,reviews the research advances of alleviation mechanism on high temperature stress at home and aboard,analyzed the unsolved problems,and provided references for further researches.
