Fungal diversity in Rhizospere and Rhizoplane soil of Avicennia officinalis from Netravathi river, Mangalore, Karnataka

Botany

Avicennia officinalis is a species of mangrove plants, also known as Indian mangrove. The young tree forms a low, dense bushy crown. When it matures, it forms a columnar tree up to 15m and may grow up to 30m. The microorganisms are known to form a healthy growth in all provided environment. This work was undertaken to study the fungal diversity in Rhizoplane and Rhizospere soil of Avicennia officinalis from netravathi river region. Rhizoplane region is the external surface of roots together with closely adhering soil particles and debris and Rhizospere region is the arrow region of soil that is directly influenced by root secretions and associated soil microorganisms. The work was carried out by inoculating Rhizoplane and Rhizospere soil of A. officinalis to different growth medias and incubated the cultured plates and then they are identified. From this work total 19 fungal species belonging to different genera were isolated and identified, among which Ascomycota were dominating with 16 species, Zygomycota with 2 species and one species of Oomycetes. The Ascomycota genera have shown high percentage of occurrence i.e. frequently occurring (5-10%) and also higher diversity in Simpson’s index.
