北方落叶果树果实日灼病研究进展

Research Progress on Fruit Sunscald of Northern Deciduous Fruit Trees

日灼病是一种由高温强光诱发的植物生理性病害,每年会给北方落叶果树生产造成很大损失。科学合理的日灼防治是果树优质丰产的重要保证。系统综述了以苹果为首的北方落叶果树果实日灼病研究进展,包括果实日灼的主要类型和症状、日灼形成的影响因素及其生理分子机制、目前生产上主要的应用防治措施,同时对未来果树日灼病研究的发展趋势进行展望,以期为今后果实日灼病研究提供依据。

Sunscald is a kind of physiological plant disease caused by high temperature and strong light.It causes great loss to the production of northern deciduous fruit trees every year.Scientific and reasonable prevention and control of sunscald is an important guarantee for high quality and high yield of fruit trees.This article systematically reviewed the research progress of fruit sunscald in northern deciduous fruit trees led by apples,including the main types and symptoms of fruit sunscald,the influencing factors of sunscald formation and its physiological and molecular mechanisms,and the main applied prevention and control measures in current production.Furthermore,the development tendency of the research on sunscald of fruit trees was prospected to offer the reference for further research.
