Abstract: Fungi growing on the woods were investigated in the Dongling Mountain Nature Reserve to understand the community composition and substrate preference of wooddecaying fungi. A total of 1007 wooddecaying fungi individuals, representing 128 species, belonging to 24 families, 11 orders were recorded on 15 tree genera. Among them, Polyporaceae, Hymenochaetaceae and Meruliaceae were dominant families, which comprised 27.34%, 17.96% and 12.5% of total species number, respectively. There were 14 dominant species, which made up 48.76% of all occurrences. And most of these dominant species were whiterot fungi. Rarefaction curves on different substrates indicated that at decay stages of 2 and 3, most individuals and species were found on host species of Quercus and Populus, especially on substrates with diameters between 0-5 cm and larger than 10 cm, as well as substrates having barks. Besides, substrates having lower numbers of individuals might have higher wooddecaying fungi diversity. Wooddecaying fungi distributed differently on different substrates. Families at different decay stages revealed that succession species were most abundant in number and diversity, while pioneer and ultimate species were less abundant in this area. The low percentage of brownrot fungi was correlated with the presence of few coniferous trees. It is suggested that substrate protection can promote wooddecaying fungi diversity.
Key words: apple orchard, water and fertilizer management, Weibei dryland, soil water.
