    Host Range and Banana Variety Resistance to Bacterial Soft Rot Pathogens

    • 摘要: 以分离获得的3个香蕉细菌性软腐病菌为接种菌株,采用针刺和注射等接种方法进行了香蕉细菌性软腐病菌寄主范围的鉴定,并对香蕉不同品种的抗性进行了测定.结果表明,在供试的15科22种植物中有21种植物可以被病原菌侵染而发病,表明该病原菌寄主范围广泛.对我国普遍栽种的7个香蕉品种的抗性测定结果表明,不同香蕉品种抗性存在差异,其中皇帝蕉为高抗品种;农科1号、大蕉和巴西蕉为中抗品种;而金粉、广粉和威廉斯B6为中感品种.

       

      Abstract: Banana soft rot, a serious disease caused by Dickeya sp., was found in Guangdong and Hainan provinces. The host range of banana soft rot pathogens in China and the disease resistance of different banana varieties were not reported. Three isolates of banana soft rot pathogens and 22 species of plants from 15 families were investigated for pathogen-host range by using artificial inoculation methods. The results indicated that three isolates had a wide host range. In addition, seven banana varieties, which widely grew in China, were used to identify the resistance to banana soft rot. The results showed that Musa AA Pisang Mas had a high resistance; Musa AAA Cavendish cv. Brazil, Musa AAA Cavendish cv. Nongke No.1, and Musa ABB Pisang had a moderate resistance; Musa ABB Pisang Awak cv. Jinfen, Musa AAA Cavendish cv. Williams, Musa ABB Pisang Awak cv. Guangfen were moderately susceptible.
