Fungal Succession During Fraxinus mandshurica Stump Decomposition in Broad-leaved and Korean Pine Mixed Forest in the Changbai Mountains, China
Ihe decomposition of Fraxinus mandshurica stumps is the key factor of the nutritional cycle of broad-leaved and Korean pine mixed forest in the Changbai Mountains.Fungi are the main contributors of the stump decomposition.The fungal diversity and succession on the stumps were investigated during the stump decomposition.The result showed that the species diversity and the biomass were rich on F.mandshurica stumps.There was no significant fluctuation of fungal biomass,but significant variation of the species was found during the stump decomposition period.The fungal diversity was higher in 3,7 and 10 years,but lower in 5 and 12 years.The prominent fungal species were found belonging Polyporaceae and Xylariaceae at a ratio of 47.34%among the total fungi.Scutellinia scutellata and Irpex lacteus were detected during the whole decomposing period.Coriolus versicolor was the largest in quantity.There was a negative correlation between the decomposition time as well as sunshine and the fungi quantity,while the positive correlation between the fungi quantity and the stump diameter during the decomposition.
