Abstract

A causal agent of bacterial soft rot in moth orchid was isolated and identified which occured in Hangzhou，Zhejiang Province in recent years. The pathogenicity test，Biolog test and fatty acid methyl esters （FAME） test were undertaken to elucidate the precise position of the causal bacterium． The results indicated that the causal agents characteristics were same to Erwinia chrysanthemi. And，16S rRNA gene sequence analysis also showed that the pathogenic bacterium was closely related to E. chrysanthemi and well separated from all other Erwinia species. Therefore，it could be concluded that the pathogenic bacterium causing bacterial soft rot of moth orchid was identified as E. chrysanthemi.［Ch，1 fig. 2 tab. 10 ref.］
