Abstract:
... In Azerbaijan chestnut (Castanea sativa) forms small patches in the natural mountainous forests growing together with other deciduous tree species. The chestnut blight fungus (Cryphonectria parasitica) was reported since 2008, and the continuous expansion of disease has been observed in the country. The purpose of present study was to identify the fungi other than C. parasitica isolated from the b ...
