灵香草细菌性软腐病是危害灵香草的一种毁灭性病害。本病在广西金秀县灵香草种植区普遍发生。融水县也有分布。1982年5月—1983年6月我们在金秀县采样。进行了病原细菌的分离培养和致病性测定,从中选取10个代表性菌株做了形态、培养性状、生理生化等方面的研究,并和白菜软腐病菌进行了比较和交互接种试验。结果表明灵香草软腐病菌和白菜软腐病菌都是同一个变种的细菌,即为Erwinia carotovora var.carotovora。血清学研究表明灵香草软腐病菌也存在不同的血清型。
Ling vanilla bacterial soft rot is a devastating disease that damages the spirit vanilla. The disease occurred in Jinxiu County, Lingxiang grass growing areas. There is also a distribution of Rongshui County. May 1982 - June 1983 We sampled in Jinxiu County. Isolation, culture and pathogenicity determination of pathogenic bacteria were conducted. Ten representative strains were selected for their morphological, cultural traits, physiological and biochemical aspects, and compared with the cabbage soft rot fungi for bacterial infection. The results show that both the soft rot fungi and cabbage soft rot fungi bacteria are the same variant, namely Erwinia carotovora var. Carotovora. Serological studies have shown that there are different serotypes of Rhizoctonia solani.
