中文摘要 | 本研究以甕菜、百喜草及甘藷為宿主,先行在溫室內接種內生菌根菌兩週後,移 植於氣霧式生長箱內進行無土栽培。營養液係使用修正之霍格藍液。綜合 14 次的生產試驗 , 已證實氣霧式生長箱可培養 Glomus aggregatum, G. mosseae, G. geosporum, G. microaggregatum, G. intraradices, G. pansihalos, G. manihotis, Acaulospora laevis, Entrophospora kentinensis 等九種菌種。且以 Glomus microaggregatum 的產孢 量最高。由於目前世界上以氣霧式生長箱所生產的菌種,只限於 Glomus 屬,本所所成功培 養的 Entrophospora, Acaulospora 兩屬孢子, 是目前世界上首次成功的先例。 此外, Entrophospora kentinensis 也是我國所發現的世界新種,以往本屬的菌種全世界只有三種 ,且全是分佈於酸性土壤中。而 E. kentinensis 不只分佈於酸性土壤中,它亦可出現在鹼 性或中性靠海邊的地區, 尤有甚者,本種可在重金屬銅的污染達 233 ppm 以上的土壤中發 現。此外,本次試驗結果顯示百喜草的產孢能力較其它宿主如甕菜及甘藷等為佳。 |
英文摘要 | In this study, host plants such as Ipomea reptans, bahia grass (Paspalum notatum) and sweet potato (I. batatas) were preinoculated by VA mycorrhizal fungi in greenhouse. After two weeks, plants were then moved to aeroponic chamers for soilless cultivation. In 14 experiments, this technique has proven to grow more than nine species of VA mycorrhizal fungi, including Glomus aggregatum. G. mosseae, G. geosporum, G. microaggregatum, G. intraradices, G. pansihalos, G. manihotis, Acaulospora laevis, Entrophospora kentinensis. Among them, the cultivation of Acaulospora and Entrophospora by this technique are new records to the world. Besides. E. kentinensis was a new species from National Kentin Park. It was nationwide and even found in soil with copper pollution up to 233 ppm. This species is an addition to the three of Entrophospora which were generally found in acidic soil. Bahia grass could produce more spores than I. reptans and sweet potato, bsed on the same species of VA mycorrhizal fungi. |
