Filamentous fungi associated with Bambusa plantations vulgaris var. Schrader vulgaris ex Wendland
Journal Title: Biotecnología Vegetal - Year 2011, Vol 11, Issue 4
Abstract
Bambusa vulgaris var. vulgaris Schrader ex Wendland is a species of a great economic importance and in the conservation of soils. Nevertheless, little information exists on the microbial communities associated to its plantations, and their impact on the soil. For that reason it is necessary to identify the cultivable filamentous fungi to understand their roll and contribution to the development of this forest species and their impact in the environment. Considering these criteria the current work had as objectives to quantify, to characterize, to identify and to conserve filamentous fungi in soils cultivated with Bambusa vulgaris var. vulgaris Schrader ex. Wendland. Samples from three soils with plantations of Bambusa vulgaris var. vulgaris Schrader ex Wendland, yagruma (Cecropia peltata L.) and eucalyptus (Eucalyptus grandis L.) as well as soil without any crop, used as control, were collected for the microbiological analysis. Decimal dilutions of soil were done in Rose Agar Bengal culture medium for strain isolation. The cultural and morphologic characteristics were described. The amount of filamentous fungi oscillated between 10 3 and 10 5 ufc/g in Bambusa vulgaris var. vulgaris Schrader ex Wendland, similar to the previous registered in plants of yagruma, eucalyptus and in the soil without any crop. A total of 13 generous were identified: Aspergillus, Botryotrichum, Cephalosporium., Cladosporium, Cunningamella, Fusarium, Paecilomyces, Penicillium, Pythium, Pyrenochaeta, Rhizoctonia, Trichocladium and Trichoderma. It was demonstrated that the communities of fungi in plantations of B. vulgaris var. vulgaris Schrader ex Wendland are diverse.
