강원도 춘천시의 소나무(Pinus densiflora)에서분리한 내생균류의 다양성

초록

Red pine (Pinus densiflora) is a dominant tree species in Korean forests. The diversity ofendophytic fungi was investigated by isolating fungi from different parts of a red pinetree during the fall and spring seasons. One hundred and fifty-two strains of endophyticfungi were isolated and classified into 42 species belonging to 29 genera. Among these,74 (49%), 47 (31%) and 31 strains (20%) were isolated from branches, leaves, and stems,respectively. The most frequently isolated species were Daldinia childiae and Biscogniauxiamaritima (28.9% and 9.8%, respectively). D. childiae was the dominant endophytic funguson branches (20 strains) and leaves (19 strains). B. maritima was most frequently isolatedfrom branches. The isolation frequencies on stems of B. maritima (6 strains) and D. childiae(5 strains) were also high. Fifty-seven isolates belonging to 19 species and 17 genera wereisolated in the spring, and 95 strains belonging to 35 species and 24 genera were isolated inthe fall. D. childiae was the most frequently isolated fungus in both spring and fall (21 and 23strains, respectively). B. maritima was also frequently isolated in both spring (7 strains) andfall (8 strains).
