台灣二葉松菌根菌接種試驗

松科（Pinaceae）植物常與外生菌根菌（ectomycorrhizal fungi, EMF）形成共生，但是愈來愈多的研究在松科植物根系發現叢枝菌根菌（arbuscular mycorrhizal fungi, AMF），本研究藉由台灣特有種松科植物台灣二葉松（Pinus taiwanensis）菌根菌接種試驗來了解外生菌根菌與叢枝菌根菌對台灣二葉松苗木生長之影響，並探討其生態上的意義。結果顯示外生菌根菌與叢枝菌根菌均可與台灣二葉松形成菌根，而外生菌根菌對台灣二葉松之生長促進能力明顯優於叢枝菌根菌。 Pinaceae plants often form symbiotic relationship with ectomycorrhizal fungi (EMF), but more and more studies have found arbuscular mycorrhizal fungi (AMF) in the roots of Pinaceae plants. In this study, we investigated the effects of ectomycorrhizal fungi and arbuscular mycorrhizal fungi on the growth of Pinus taiwanensis, an endemic species in Taiwan, by inoculation experiment, and explored the fungi's ecological significance. The results showed that both ectomycorrhizal fungi and arbuscular mycorrhizal fungi could form mycorrhiza with Pinus taiwanensis, and the growth-promoting ability of ectomycorrhizal fungi was significantly better than that of arbuscular mycorrhizal fungi to Pinus taiwanensis.
