摘　　要：试验明确枣干腰缩果病在田间呈现３种症状类型，即干腰型、干肩型和干蒂型。对上述３种症状的病果分离结果表明其病原种类没有明显差别，都以真菌为主，其中细交链孢菌比例最大。从开花期至采收前，每隔１０ｄ采样分离表明，病菌从花期至收果前均可造成侵染。The occurrence and symptoms of jujube fruit shrink were investigated in 1996-1997. Symptoms were divided into three groups including the head shrink, the middle shrink and the base shrink. The results of isolation of three types diseased fruits showed that pathogens which induced three types symptom were the same pathogens and Alternaria tenuis was the main pathogen. Samples were collected and isolated every 10 days between flower period and harvest and the result showed that jujube fruits could be infected in all growing period.
