Abstract
For the investigation of the potentials of ectomycorrhizal (ECM) fungi on pine seedlings for reforestation on fire-damaged forest lands, six months old seedlings of Pinus densiflora, which were artificially inoculated or non-inoculated with Pisolithus tinctorius, were transplanted into the fire-damaged forest land. Seedling mortality was recorded as 3.5% for the seedlings inoculated with P. tinctorius at three months after transplanting, while it was 70.5% for the non-inoculated seedlings. Mycorrhizal root formation was shown as typically Y-branched type, and thier rate was 82% for inoculated seedlings, but it was 52% for non-inoculated. Comaprisons in seedling height, fresh weight, and dry weight between pine seedlings inoculated or non-inoculated with P. tinctorius at every 3 months till 9 months after transplanting showed that the inoculated seedlings were much better in all criteria as compared to the non-inoculated at the level of 63%, 35%, 18% in seedling height, 206%, 114%, 70% in fresh weight, and 187%, 109%, 63% in dry weight, respectively. The percentages were decreased by the elapse of time, which indicate that P. tinctorius give a growth-stimulating effects on seedlings at the early stage. T/R ratio for inoculated and non-inoculated seedlings after 9 months was 1.75 and 1.90, respectively.
모래밭버섯 (Pisolithus tinctorius) 균근균을 접종한 소나무와 접종하지 않은 소나무를 6개월간 육성하여 산불훼손지에 식재 3개월후에 묘목의 고사율을 조사한 결과, 균근균 접종 소나무묘목의 경우는 3.5%만이 고사하였으나, 균근균 무접종 소나무 묘목는 29.5%만이 생존하였다. 모래밭버섯 균근균을 접종한 소나무 실생묘의 뿌리에 Y분지형의 균근이 형성되었고, 균근 형성율은 모래밭버섯 균근균 접종 소나무묘목의 경우에는 약 82%, 무접종 소나무묘목은 52%로 나타났다. 모래밭버섯 균근균 접종 소나무묘목을 무접종 소나무묘목에 비교하였을 때 3개월.6개월.9개월 경과시 체장은 각각 63%.35%.18%, 생중량은 각각 206%.114%.70%, 건중량은 각각 187%.109%.63% 높게 나타났고, T/R율은 산출한 결과 9개월 경과시 모래밭버섯 균근균 접종 소나무묘목은 1.75, 무접종 소나무묘목은 1.90으로 모래밭버섯 균근균접종 묘목의 지상부와 지하부의 생장이 균형있게 촉진되었다.
