溃疡病是危害性最大的柑桔细菌性病害之一,利用植物检疫手段阻止柑桔溃疡病病菌的传播和传入,是行之有效的方法。但是,随着柑桔不同种类对溃疡病菌存在品种间的抗病能力被证实和溃疡病菌生理分化的不断被发现,引起苗木检疫问题争议。温州蜜柑苗木检疫尤为突出。迄今为止,投有典型的事例能说明溃疡病能象危害甜橙一样危害温州蜜柑,但温州蜜柑的所有品系对溃疡病并不表现免疫。为解决这一矛盾,笔者自1985年秋开始,对本县柑桔种植面积较大的7个乡镇10个果场,进行一次全面普查,结合对苗 Canker disease is one of the most damaging citrus bacterial diseases. It is an effective method to use plant quarantine to prevent the spread and introduction of citrus canker. However, with the different types of citrus canker disease resistant to the existence of inter-species resistance was confirmed and the pathogenesis of ulcer bacteria continued to be identified, causing quarantine problems of seedlings controversy. Wenzhou Satsuma nursery stock quarantine is particularly prominent. So far, a typical example shows that canker disease endangers Satsuma mandarin just as it does to orange, but all strains of Satsuma do not show immunity to canker disease. To solve this contradiction, the author started from the autumn of 1985, conducted a comprehensive survey of 10 fruit farms in 7 towns and townships with large citrus cultivation area in the county,
