中文摘要 | 本研究自褐化壞疽病斑之芒果果實表面分離出18個細菌菌株,發現其中MB-9菌株可於人工接種下引起臺灣原生種芒果與愛文芒果之老葉與新葉褐化壞疽。利用人工接種系列稀釋之MB-9菌株於芒果新葉,發現200CFU之接種菌量即可導致褐化壞疽病徵之表現。經光學與電子顯微鏡之省胞形摯與構造之觀察、培養特性、生理生化反應及血清反應測試,證實MB-9菌株為Pantoea agglomerans (syn. Erwinia herbicola)。本報告顯示Pantoea agglomerans (syn. E. herbicola)具有危害芒果葉片的潛在危險性。 |
英文摘要 | Mango is one of the most important tropic fruits in Taiwan. Necrotic lesions are commonly found on ripen fruits of native mango and cultivar “Irwin”. Eighteen bacterial strains were isolated from necrotic lesions of native mango fruits. Wound inoculation showed that strain MB-9 caused necrosis on immature and mature mango leaves of native mango and cultivar “Irwin”. Immature mango leaf wound inoculated with serially diluted bacterial suspensions of MB-9 strain revealed that inoculation with 200 CFU was able to cause necrotic symptom. Bacterial identification based on microscopic, cultural, physiological and biochemical characteristics and serological reactions indicates that MB-9 is a potential pathogen causing necrosis on mango leaf. |
