Identification of Dickeya chrysanthemi in introduced hyacinth bulbs
摘要
Abstract
A bacterial strain 5093-1 was isolated from the hyacinth bulbs introduced from the Netherlands which had a typical soft rot symptom. Its colonial morphology was observed,and its path-ogenicity and hypersensitive reaction were tested. Also the 16S sequence analysis and Biolog testing were made. The results showed that the artificial inoculation with the isolate could cause hyacinth seedlings,potato tubers and butterfly orchids to produce rot and also could lead tobaccos to hypersensitive necrosis. The sequence similarity between the isolate and Dickeya chrysanthemi was 99. 6%, and the isolate was identified as Dickeya chrysanthemi by Biolog testing. It was concluded from the above results that the strain 5093-1 is Dickeya chrysanthemi.关键词
