中文摘要 | 本研究以人工接種方式,比較「北蕉」、「新北蕉」、「臺蕉5 號」、‘Gros Miche’、「南華蕉」及「玫瑰蕉」等6 種受試香蕉品種,對香蕉黃葉病之耐受程度。試驗以出瓶後5 wk 大小一致之蕉苗進行接種,追蹤接種後黃葉率、罹病率;此外,針對接種黃葉病原之香蕉假莖褐化部位進行定量分析,並配合即時聚合酶鏈鎖反應技術檢測接種後香蕉假莖內病原菌之含量,作為耐病程度之量化評估。結果顯示「玫瑰蕉」為6 種供試品種中相對最抗黃葉病的品種,而 ‘Gros Michel’ 為相對最為感病之品種。 |
英文摘要 | In this study, for comparing different levels of tolerance in banana species to Fusarium wilt disease, several cultivars, i.e., 'Pei Chaio', 'Formosana', 'Tai Chiao No. 5', 'Gros Michel', 'Pisang Awak', and 'Rose', which were commonly cultivated in Taiwan, were inoculated artificially with Fusarium pathogen. Percentages of chlorosis were estimated after culturing two-month-old seedlings of bananas in Fusarium-inoculated soil in greenhouse. Besides, we examined browning region of corm sections of Foc-inoculated plants quantitatively and qualitatively and estimated the amounts of Foc in each corm section by real-time PCR method. Results showed that cultivar 'Rose' was the more resistant cultivar among six cultivars while 'Gros Michel' was the more susceptible cultivar. |
