| Abstract: | Pathogen identification of the soft rot disease on edible cactus revealed that the pathogen was Erwinia carotovora subsp. carotovora, which showed identical physiological and biochemical characteristics with the contrast strain that caused the soft rot of Chinese cabbage, while discrepancy of the cultural characteristics between them could be discerned. Pathogenicity test experiment demonstrated that this strain could cause soft rot on a wide range of vegetables. |
