The relationship between abundance of wood macrofungi on chestnut-leave Oak (Quercus castaneifolia C.A.M.) and hornbeam (Carpinus betulus L.) and physiographic factors (Case study: Kheyroud forest, Noshahr)

Fungi include a large group of organisms that are found in different ecological conditions and are important components in forest ecosystems. The northern forests of Iran are mountainous mixed forests، and have high biological diversity. The aim of this research was asses influence of physiographic factors on abundance and diversity of wood macrofungi. After of primary field inspection fungi samples were collected in summer and fall seasons from oak and hornbeam trees. The collected sampeles belong to compartments 110، 207 and 311 in educational and research forest of the University of Tehran. Totally 190 samples of macrofungi from oak and hornbeam tress were collected in three compartments، 114 samples of collected specimens belong to wood decay fungi. The collected samples were identified according to standard sources based on macroscopic and microscopic characteristics of fungi، in Iranian Research Institute of Plant Protection. The Duncan test was used for statistical analysis by SAS software. Results showed significant relationship between the physiographical factors (altitude، slope، and aspect) and abundance of fungi in (p<0. 01)، the most of macrofungi species were found in altitude between 800 to 1200 M، on slopes 0 to 20 percent and in the southwest and west aspects.
