| Research Abstract |
We investigated the decomposition of leaf litter and the composition of litter-decomposing fungal community under snow cover in some forest stands in Hokkaido, and their extracellular enzyme productivity at low temperature. It was observed that while the oak and fir foliage litter lost their original weight under snow during the winter season, some fungi appeared or increased the frequency. Some fungi isolated from oak litter were found to extend the mycelia on the media and indicated ligninolytic activity at 0℃. These results suggest that some litter-decomposing fungi, which have potential ability to degrade lignin at 0℃, significantly contribute the litter decomposition under snow cover.
