dc.description.abstractEndophytic fungi (EF) are microorganisms that live asymptomatically within plant tissues. They can confer benefits to the plant as inducers of resistance to pests and diseases, tolerance to abiotic factors, plant growth promoters and mycoparasites of pathogens. This study aimed to isolate, identify, and determine occurrence frequency of endophytic fungi in stems and leaves of blueberry plants collected from ten farms in Lima and Ica Region, Peru. Productive branches of 39 healthy plants were sampled. For the isolation of EF, 702 tissue sections were disinfected and transferred to Petri dishes with potato dextrose agar (PDA) medium, and reproductive structures were induced for identification. A total of 134 EF strains were isolated successfully. Nine genera were identified (Trichoderma, Aspergillus, Alternaria, Ulocladium, Cladosporium, Fusarium, Nigrospora, Lasiodiplodia and Stemphylium). EF occurrence frequency varied greatly between organs, being in leaves more frequent than the stems; likewise, the genera Alternaria and Cladosporium were the most frequent and with most colonized in plant tissues, while Aspergillus, Ulocladium and Lasiodiplodiawere the least frequent. These strains could be useful to control plant diseases and, therefore, of great interest in sustainable agriculture.
dc.description.abstractLos hongos endófitos (HE) son microorganismos que viven asintomáticamente dentro de los tejidos vegetales. Pueden conferir beneficios a la planta como inductores de resistencia a plagas y enfermedades, tolerancia a factores abióticos, promotores del crecimiento vegetal y micoparásitos de patógenos. Este estudio tuvo como objetivo aislar, identificar y determinar la frecuencia de ocurrencia de hongos endófitos en tallos y hojas de plantas de arándano recolectadas en diez fincas en la Región Lima e Ica, Perú. Se muestrearon ramas productivas de 39 plantas sanas. Para el aislamiento de EF se desinfectaron 702 cortes de tejido y se transfirieron a cajas Petri con medio papa dextrosa agar (PDA) y se indujeron estructuras reproductivas para su identificación. Se aislaron con éxito un total de 134 cepas de EF. Se identificaron nueve géneros (Trichoderma, Aspergillus, Alternaria, Ulocladium, Cladosporium, Fusarium, Nigrospora, Lasiodiplodia y Stemphylium). La frecuencia de ocurrencia de EF varió mucho entre órganos, siendo más frecuente en hojas que en tallos; asimismo, los géneros Alternaria y Cladosporium fueron los más frecuentes y con mayor colonización en tejidos vegetales, mientras que Aspergillus, Ulocladium y Lasiodiplodia fueron los menos frecuentes. Estas cepas podrían ser útiles para el control de enfermedades de las plantas y, por tanto, de gran interés en agricultura sostenible.
