摘　　要：环境胁迫一直以来是影响植物生长和农作物产量的主要因素,而覆盖植物地上部分最表层的表皮蜡质在植物生长发育、适应外界环境方面起着重要作用。本文综述了近年来国内外在表皮蜡质对环境胁迫响应方面的研究成果,主要体现为对UV、空气湿度、水分、温度和病害等胁迫的抵御作用,并对今后的蜡质研究进行了展望。Environmental stress has always been a factor to affect plant growth and the outputs of crop.Epicuticular wax cover the outer surface of land plants plays crucial roles in plant growth and development,and adaptation to environment.The epicuticular wax protect plants from bacterial and fungal pathogen,UV radiation,water stress and low temperature＇s injury.The crystalline structure and chemical composition of plant wax are most sensitive in response to the outside environment conditions.This paper reviewed the current progress on function and response of plant epicuticular wax under environmental stresses,including both the abiotic factors such as UV radiation,water,humditity and temperature and biotic factors such as pathogens.The direction of the future wax study was also discussed.
