摘要
马铃薯疮痂病(potato common scab)是由放线菌目链霉菌属疮痂病链霉菌(Streptomyces spp.)引起的土传兼种传病害,在世界各马铃薯种植区域广泛分布,已成为马铃薯生产上四大主要病害之一,严重影响着马铃薯的商品性及加工品质,给马铃薯产业带来巨大的经济损失。在世界范围内,每年可造成千亿美元的经济损失。马铃薯疮痂病在我国很多省(自治区)都有不同程度的发生,并有逐年扩大和加重的趋势。本评述对马铃薯疮痂病症状、发病规律、病原菌种类与分布进行了归纳,阐述了病原菌的鉴定及致病机理,总结了不同防治措施的特点,并对今后研究重点进行展望,以期为病原菌的深入研究和防治奠定理论基础。
Potato common scab is a soil and seed-borne disease caused by Streptomyces spp.,which belongs to actinomycete.It is widely distributed in potato growing regions around the world and has become one of the four major diseases in potato production.It seriously affects the fresh and processing quality of potatoes,and causes huge economic losses to the potato industry.Potato common scab has occurred in many provinces(autonomous regions)in China to varying degrees,and has a trend of aggravating year by year.This review summarized the symptoms of potato scab,the occurrence and the species and distribution of pathogens,described the identification and pathogenesis of pathogens,summarized the characteristics of different prevention and control measures,and prospected the future research emphases for better control of pathogens.
