山藥(Dioscorea spp.)接種叢枝菌根菌對植株生長發育之影響
Effect of Arbuscular Mycorrhizal Fungi (AMF) Inoculation on the Growth and Development of Yams (Dioscorea spp.)
摘要
山藥(Dioscorea spp.)為國際性重要糧食和藥用作物，也是華人社會普遍使用之保健用生藥材料，是近年來在台灣頗受重視的作物。叢枝菌根菌(arbuscular mycorrhizal fungi, AMF)為一種在自然界分佈廣泛能與植物根部共生的有益真菌，本研究以台灣常見之紫玉血薯(D. alata L.var. purea(Roxb.)M.)和陽明山山藥(D. opposita Thunb)等兩個品種，接種六種叢枝菌根菌Glomus clarum Schenck & Smith(Gc)，G. etunicatum Becker & Gerdemann (Ge)，G. fasciculatum (Thaxter) Gerd. & Trappe emend. Walker & Koske (Gf)，G. mosseae (Nicol. & Gerd.) Gerdemann & Trappe(Gm)，Gigaspora sp.(Gg)及Acaulospora sp.(Asp)等，探討對山藥植株生育之影響。研究結果顯示Gc、Ge、Gm和Asp對於莖寬與葉片的發育均有明顯的提升效果，Gc、Ge和Gf可促進葉片醣類的含量，此外Gf和Asp有提升山藥葉片蛋白質含量的能力。叢枝菌根菌接種於山藥，在栽培與生產上具有發展的潛力，可做為微生物肥料之利用。

Yam (Dioscorea spp.) is one of the most important crops due to its nutritional value and medicinal purpose. It is historically treated as an medical herb for health in Chinese and has gained increasing attention in Taiwan during the recent decade. The symbiotic association between arbuscular mycorrhizal fungi (AMF) and root of plants is widespread in the natural environment. Two yam species, D. alata L. var. purea (Roxb.) M. and D. opposita Thunb were inoculated with six species of AMF, such as Glomus clarum Schenck & Smith (Gc), G. etunicatum Becker & Gerdemann (Ge), G. fasciculatum (Thaxter) Gerd. & Trappe emend. Walker & Koske (Gf), G. mosseae (Nicol. & Gerd.) Gerdemann & Trappe (Gm), Gigaspora sp (Gg) and Acaulospora sp (Asp) for evaluate their effect on the plant growth and development of yam. Results showed that inoculation with Gc, Ge, Gm and Asp improved the stem diameter and the development of leaves. Gc, Ge and Gf can promoted the content of soluble carbohydrate in leaves, in addition Gf and Asp were able to increase the soluble protein in leaves of yam. It has the potential in yam production and can be used as microbial fertilizer.
