中文摘要 | 本研究針對出雲山苗圃培與之9種苗木進行菌根調查,結果顯示,各樹種優勢苗木與劣勢苗木高生長之差異達1.33-4.51倍,地徑生長同樣呈倍數的差距。苗木菌根型態以內生菌根為主,各樹種優勢苗木之菌根感染率平均為31.5%,劣勢苗木菌根感染率平均則為8.8%,菌根依賴度以楊梅351%最高,紅檜則最低僅33%。苗圃中內生菌根樹種平均可與3種以上菌種共生,但外生菌根樹種則共生菌種極少,若欲在此苗圃進行外生菌根苗木的培育,應進行外生菌種的引種。盆栽培養法大量繁殖內生菌種,以蕃薯藤為宿主的產孢量最高,菌根孢子則以Acaulospora laevis產孢量最高(1468±255 個/100 ml)。接種菌根方式以在發芽盤時期進行接種為佳,菌根感染平均可達57-65%。苗圃藥劑噴灑處理,對於生長於出雲山苗圃的臺灣櫸與臺灣肖楠苗木都不具影響,對苗木根系的菌根感染率也不具有差異。 |
英文摘要 | There are nine species tree seedlings were investigated in Chu-Yun-Shan nursery for mycorrhizal status. Result obtained showed that the height growth of dominant seedlings were 1.33-451 times superior to those inferior seedling; meanwhile, the root collar diameters had the same times as foregoing. Seedlings mycorrhizal symbiosis were mainly vesicular-arbuscual mycorrhizae (VAM). The average VAM colonization of superior seedling was 31.5%, and which of inferior seedling was only 8.8%. The highest mycorrhizal dependency among all species was Myrica adenophora (351%); however, Chamaecyparis formosensis only 33% was the lowest. Each VAM seedling could be symbiosis with more than three VAM fungi in the nursery; nevertheless, the ectomycorrhizal seedling only symbiosis with few. It was necessary that inoculating superior ectomycorrhizal fungus when cultivating ectomycorrhizal seedlings. Mass spores production with Ipomoea batatas had the highest, especially Acaulospora laevis (1468±255 spores/100 mL). The best way for mycorrhizal inoculation was using germination disk, which could reach about 57-65% mycorrhizal colonization. Insecticide and fungicide applications were no influence on the height growth and mycorrhizal colonization of Zelkova serrata and Colocedrus formosana in Chu-Yun-Shan nursery. |
