| 摘 要： | 2004~2006年，在山东省的临淄、聊城、寿光、临沂等12个县市保护地栽培的西葫芦中发现一种严重危害茎基部的细菌性病害。从22批次55株西葫芦病株标本中，经分离纯化获得135个菌株，从中选出部分菌株按柯赫法则对其进行致病性测定，均产生与田间相同症状。对病原菌形态、染色反应、培养性状和生理生化等几项试验结果表明，病原菌为胡萝卜软腐欧文氏菌胡萝卜软腐亚种Erwinia carotovora subsp. carotovora。

| Abstract: | A bacterial disease was found on summer squash basal stems in protected vegetable fields of 12 counties in Shandong Province from 2004 to 2006. One hundred and thirty-five strains were isolated from 55 diseased plants. The pathogenicities of some strains showed that all these strains could cause the same symptoms as in the open field. The pathogen was identified as Erwinia carotovora subsp, carotovora based on the morphology, dyeing reaction, culture characteristics, physiological and biochemical tests. |
