초록

자작나무시루뻔버섯(차가버섯)은 살아있는 나무에서만 자라는 귀중한 약용버섯이다. 그러나 아직까지 인공재배가 아닌 자연 채취에 의존하고 있다. 자작나무시루뻔버섯을 인공적으로 재배하기 위해 2007년에 자작나무시루뻔버섯 톱밥종균을 자작나무에 접종하였으며, 그 후 균을 접종했던 자작나무에서의 버섯 생장을 9년간 조사하였다. 자작나무시루뻔버섯은 연간 1 cm 미만으로 생장하였고, 9년간 가장 크게 자란 버섯 개체의 경우에는 9 cm까지 생장하였다. 자작나무시루뻔버섯균이 생존한 것과 생존하지 않은 것의 나무 생장(diameter at breast height, DBH)에는 차이가 없었다. 결론적으로 자작나무시루뻔버섯의 인공재배는 성공적이었으며, 버섯 생산성을 고려할 때 자작나무시루뻔버섯균을 접종할 기주는 가능한 한 큰 자작나무를 선택하여 사용하는 것이 좋을 것으로 판단된다. 아울러 자작나무시루뻔버섯의 접종 성공률을 높일 수 있는 개선 방법 또한 필요하다.

Chaga mushroom (Inonotus obliquus), which has invaluable medicinal uses, grows only on living trees. To date, it is still harvested from its natural habitat and is not cultivated artificially. We artificially cultivated chaga mushrooms by inoculating its sawdust spawns on Betula platyphylla var. japonica in 2007, and monitored mushroom growth on the inoculated trees for 9 years. The mushrooms grew less than 1 cm per year, with the largest mushroom growing up to 9 cm in the 9 years of study. There was no difference in the growth (diameter at breast height) of trees with viable and non-viable I. obliquus. In conclusion, artificial cultivation of chaga mushroom was successful. Our findings suggest that selection of large B. platyphylla var. japonica as host tree could lead to better I. obliquus productivity. Further improvements of the method are needed to increase the success rate of I. obliquus inoculation.
