Aislamiento de microorganismos benéficos asociados en plantas sanas de fresa (Fragaria x Ananassa) en la comunidad Angahuana Bajo
(2025-02) Iza Bravo Liliana Patricia; Pomboza Tamaquiza Pedro Pablo
The present study carried out on the isolation of associated beneficial microorganisms in healthy strawberry plants (Fraggaria ananassa). Soil samples were obtained from strawberry crops located in the Angahuana Bajo community, Santa Rosa Parish. It was obtained from 8 plants from two plots. Culture media were prepared and the microorganisms were inoculated in each Petri dish. The plates were then analyzed with the help of a microscope and information on colony formation was recorded. The developed fungi were isolated and performed by microculture to obtain pure cultures. These samples were identified and morphological characterization was carried out. The number of hyphae, conidia, conidiophores and number of spores were counted. The front and back color of each mushroom was recorded. The main results obtained were the isolation of 5 fungi which were identified and characterized. Within the study carried out, 4 species of pathogenic fungi and one beneficial fungus were found. In the rhizosphere soil, the genus Fusarium sp and the genus Penicillium sp were the most frequently colonized by pathogenic fungi; the genus Brachysporium sp and Cladosporium sp were less frequently colonized, and the beneficial fungus was found to be the genus Trichoderma sp. The beneficial fungus helps to improve the access and absorption of nutrients, such as the decomposition of organic matter. In addition, it helps to protect phytopathogenic fungi, which are related to crops.
