Abstract

Eleven fruit bodies of Ganoderma sp. were collected from eight locations throughout the forest of Kangwon province and Kyunggi province in Korea. The hosts in forest were cut trunks of Quercus dentata, Q. variabilis, Prunus peria and Alnus japonica that was newly surveyed but 5 isolates were collected at the farms of Ganoderma mushroom. Most fruit bodies were formed solitarily on the cut trunks but GS-106 isolate grown in crowds on cut trunk of Alnus japonica. Optimal temperature ranges for isolates of species studied were: G. applanatum $28^{\circ}C{\sim}30^{\circ}C$, G. lucidum $28{\sim}30^{\circ}C$, G. neo-japonicum $28^{\circ}C$, and G. tsuage $26^{\circ}C$ and all the species grew slowly at the $32^{\circ}C$. Hamada medium adjusted with pH 5.4 and 6.2 is better than other media for mycelial growth. Mycelial morphological characteristics of six species were studied: G. applanatum, G. lucidum and G. neo-japonicum produced typical type of staghoru hyphae but G. oregonens and G. valeosiacum produced staghoru hyphae with a branch of grape form. Clamp connection was observed on hypha of G. applanatum, G. lucidum, G. oregonense and G. valeosiacum except G. neo-japonicum with node type. Chlamydospore was produced by G. applanatum, G. neo-japonicum. and cuticular cells were present on hyphae of G. lucidum, G. neo-japonicum, G.oregonense and G. tsugae.

Ganoderma속균은 약효가 인정되어 많이 인공 재배되어 이용되고 있으나 본 속균에 대한 기초적인 연구가 미흡한 실정이므로 본 연구에서는 영지 속균을 채집하여 분리 동정하였으며, 또한 배양적 특성과 형태적인 특징을 조사하였다. 영지속균은 경기도와 강원도 11개 장소의 참나무, 아카시나무, 오리나무 등에서와 6재배농가에서 채집되었다. 대부분의 영지는 하나의 버섯이 그루터기에서 형성되나 오리나무에서는 다수가 형성되었다. 영지속균의 균사 생장적온은 G. applanatum, G.lucidum, G. neo-japonicum에서는 $28{\sim}30^{\circ}C$이었고, G. tsugae에서는 $26^{\circ}C$이었으나 $32^{\circ}C$에서는 천천히 생장하였다. Hamda배지를 pH 6.2로 조정하였을 때 균사생장이 가창 좋았다. 6종의 공시균주에 대한 균사의 형태적인 특정으로 G. applanatum, G. lucidum, G. neo-japonicum은 staghorn를 형성하였으나 G.oregonens, G. ualeosiacum은 포도형의 가지를 가진 staghorn균사를 형성하였다. Clamp connection은 G. applanatum, G. lucidum, G. oregonense, G. valeosiacum균의 균사에서 관찰되었으나 node형을 가진 G. neo-japonioum에서는 형성되지 않았다. 후막포자는 G. applanatum, G. neo-japonicum에서 형성되었으며, cuticular cell는 G. lucidum, G. neo-japonicum, G. oregonense, G. tsugae의 균사에서 형성되었다.
