BIODIVERSITY OF WOOD DECAY FUNGI ON DALBERGIA SISSOO

Abstract

A survey was conducted on biodiversity and distribution of wood decay macro fungi in northern social forest regions in five upazillas (Dupchanchia, Adomdighi, Sonatola, Sherpur and Dhunot) of Bogra district in Bangladesh on sisso tree (Dalbergia sisso). A total of fifty (50) plants were randomly selected for collection of wood decay fungi in each location. The northern region of Bangladesh (Bogra) is located at 24°32' and 25°07' north latitudes and between 88°58' and 89°45' east longitudes.“Dalbergia sissoo” commonly known as Indian Rosewood is a large deciduous tree that produced very heavy strong and stout wood with of good quality. Now a days the plant is in threat (dying) due to fungal infection and other unknown reasons. A total of 43 samples of wood decay fungi belonging 9 families were collected and identified to 15 genera and 21 species. The predominant genus was Ganoderma. Among the Genoderma spp., the highest density (23.2%) and frequency (55%) was found in Ganoderma tsugae. Among the fleshy macro fungi, the highest density (55%) and frequency (33%) was found in Psathyrella candolleana. The macro fungi were preserved in Sher-e-Bangla Agricultural University Herbarium of Macro Fungi (SHMF).
