自从1981年以来,日本的静岗县温室网纹甜瓜发生一种新病害,该病通常在采收上市7～10天后,开始在果实表面形成小片圆形病斑,直径约2～7 mm,水渍状,淡绿色,后扩展至20～60mm,并在网纹下产生浅凹陷病块。病果成软腐,果实表面看不见病菌菌丝。根据本文研究鉴定该病菌为:甜瓜间座壳(Diaporthe melonis Berahaet O’Brien)的新变种 Diaporthe melonis var.brevistylospora Kobayashi et Ohsawa 及葫芦科拟茎点霉 Phomopsis curcurbitae McKeen sensuBehara et O’Brien(无有性阶段)。
Since 1981, a new disease has emerged in greenhouse greenhouse melon in Jinggang County, Japan. The disease usually begins to form small round lesions on the surface of fruit after 7-10 days harvesting and harvesting, with a diameter of about 2 to 7 mm, Water stains, light green, after extended to 20 ~ 60mm, and in the shallow groove caused by the depression of disease. The disease becomes soft rot, the surface of the fruit can not see the bacteria mycelium. According to the study identified in this study: Diaporthe melonis Berahaet O’Brien new variant Diaporthe melonis var.brevistylospora Kobayashi et Ohsawa and Cucurbitaceae Phomopsis curcurbitae McKeen sensuBehara et O’Brien (no sexual stage).
