1 症状 枣疯病的主要症状是:由于花器退化,芽的反常萌发,枝条的反常生长而形成枝叶丛生的现象。花器退化为营养器官,花梗变长4～5倍,萼片、花瓣、雄蕊均变成小叶;枝条上的正芽、隐芽都萌发形成发育枝;枣股也就成发育枝。当部分枝条发病时,健枝仍能结果,但果实着色不匀,果面凹凸不平,形成红绿相间的花脸枣,果实糖分降低,果肉发糠,品质低劣。同时病树根部萌生大量根蘖,许多根蘖聚生呈刷子状,后期根部皮层腐烂。枣 1 Symptoms The main symptoms of jujube madness are: due to flower degeneration, abnormal germination of buds, abnormal growth of branches and the formation of follicles phenomenon. Flower organs degenerated into vegetative organs, pedicel 4 to 5 times longer, sepals, petals, stamens become leaflets; shoots on the shoots, buds germinate to form the development of branches; jujube shares also become developmental branches. When some branches of disease, the sticks can still result, but uneven fruit coloring, uneven fruit surface, the formation of red and green flower face jujube, fruit sugar decreased, the pulp of bran, poor quality. At the same time, diseased roots germinated a large number of root tillers, many root tillers polygated brush-like, late root cortex decay. date
