【摘要】 UV-B辐射增强对农业生态系统和作物产量的影响已引起国内外广泛关注。本文结合近年来国内外研究成果,介绍了UV-B辐射胁迫下植物应激合成与累积类黄酮的特征,考察了类黄酮在抵御UV-B辐射胁迫中的生态生理作用及其机理,探讨了类黄酮与其他抗UV-B辐射机制的关系,分析了未来该研究工作的若干取向。更多还原

【Abstract】 The influence of enhanced UV-B radiation on agricultural ecosystem and crop output is an area widespreadly attracting researchers.The paper introduced the characteristics and accumulation of flavonoid in plants whose synthesis is stirred up under UV-B radiation.Ecological and physiological effects and mechanism of flavonoid resistance to UV-B radiation are also analyzed.The relationship between flavonoid and other anti-UV-B radiation machanism are discussed from several angles laying the basis for future studies.更多还原
