【摘要】 从云南省马铃薯产区取样 ,用厌气技术分离纯化了 42个软腐欧文氏杆菌菌株。根据品种差异代表性地选出2 0个菌株进行主要细菌学性状鉴定 ,并在此基础上进行分类。结果表明 :13个菌株 (占 6 5 % )是Erwiniacarotovo ravar.carotovora ,3个菌株 (15 % )是Erwiniachrysanthemi ,其它 4个菌株根据其生理生化特性划归为中间型 ,介于Erwiniacarotovoravar.carotovora和Erwiniachrysanthemi之间。

【Abstract】 From the potato tubers in Yunnan, 42 soft rot Ewinia strains were isolated and purified by using anaerobic method. Main bacteriological characters from 20 strains were determined, which were selected from the different potato cultivars. The result indicated that out of 20 strains, 13 ones were found to be Erwinia carotovora var. carotovora , 3 ones to be Erwinia chrysanthemi , and others were classified as the intermediate type between Erwinia carotovora var. carotovora and Erwinia chrysanthemi . Based on their physiological and biochemical characters, the classification was done.
