出雲山苗圃菌根調查與苗木菌根接種試驗

Abstract

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Acau

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
