| Research Abstract |
The phospholipid fatty acid (PLFA) analysis was used to estimate the changes in microbial community structure during decomposition of wood pegsof kojii wood, sugi heartwood and sapwood buried by half of the length in soil of three study sites at the ridge, side and valley sites along the slope under the broad-leaved forest in June 2007. The PCA analysis of PLFA profiles in the ridge site shows that the microbial community structure could divided into three groups each for kojii wood, sugi heart and sapwood pegs after 2 months, but those of kojii and sugi sapwood went into the one group after 12 months, resulting to only two of different community groups, one was composed with those in kojii and sugi sap wood, and the other was that in sugi heart wood. However, these two groups were no longer distinguishable after 24 months. These results suggested that the microbial community could be sifted easily in the surface of kojii wood and sugi sapwood pegs, while gradually in sugi heart wood peg, and the communities in three kinds of wood were finally sifted to the same structure during 24 months.
