A comprehensive mycofloral diversity of pedosphere, phyllosphere and aerosphere of Som. ( Persea bombycina Kost.) in lower Brahmaputra valley of Assam

This study has been done for a period of 2  years from 2014 to 2016 in Goalpara district of Assam, India. Mycoflora of pedosphere (rhizosphere and non-rhizosphere), phyllosphere and aerosphere were identified and correlated with the seasonal variation. The rhizosphere, air and phylloplane were dominated byRhizopus stolonifer (22.13%; 15.08%; 24.01%), whileAspergillus niger (12.63%) dominated non-rhizospheric soil. In summer, soil was majorly dominated byA. niger,Aspergillus fumigatus andCurvularia lunata, whileR. stolonifer,Aspergillus clavatus andPenicillium chrysogenum dominated the winter soil.Pestalotiopsis disseminata is one of the major pathogens of Som and was found highest in aerosphere followed by phyllosphere. Temperature between 25 and 28  °C with 70–80% of relative humidity favoursP. disseminata. This study provides a deep insight into the fungal diversity of Som with respect to pedosphere, aerosphere and phyllosphere, and this knowledge can be used to better select the plantation area and design different disease management strategies to sustain and proliferate the industry for socioeconomic development and to conserve its cultural essence.
