茶轮斑病发生为害特性及其茶树抗病研究进展

Research Progress on Tea Grey Blight and Disease Resistance of Tea Plants

摘要: 茶轮斑病是茶树主要病害之一。本文基于近十年来（2013—2023年）国内外研究者对茶轮斑病的研究现状，对该病的发生为害特点、病原菌种类及其致病机理、茶树对轮斑病的抗病机理以及病害防控措施等进行了综述，并对今后的研究方向作了展望，以期为茶园绿色防控和茶树抗病育种提供理论依据。

Abstract: Tea grey blight is a major foliar disease of tea plants worldwide. The symptoms generally appear on mature leaves infected by different Pestalotiopsis species. The disease can spread quickly under warm and humid climates. If many plants are infected and defoliated, it can become a serious problem for the plantation. This article summarizes the reports published in 2013-2023 relating to the studies on the occurrence, typical damages on tea plants, major pathogens involved, infection and resistance mechanisms as well as existing disease control and prevention techniques of tea grey blight. Suggestions for future studies to foster green control and breeding of resistant varieties in combating the disease are discussed.
