Resumo: | Endophytic fungi are microorganisms that live a part of their life in a host, no causing apparent damage. These fungi have been used for different purposes, such as biological control of pathogens, as producers of volatile organic compounds and promoters of plant growth. Thus, aim of this work was to evaluate effect of 12 endophytic isolates belonging to the genus Acremonium, Muscodor and Simplicillium on the development of two common bean cultivars (BRSMG Madrepérola and BRSMG União). For fungi inoculation, cultivars seeds were placed in Petri dishes in contact with fungi radicle emission. Subsequently, seeds were sown in pots and kept in greenhouse until harvest. Cultivars seeds inoculated were used as controls. Two experiments were carried out in greenhouse, in factorial scheme 13x2, with 12 endophytic fungi and control and two common bean cultivars. Experiments were conducted in a randomized complete block design with three replicates. Evaluated traits were: plant height (AP), root length (CR), leaf index (IF), number of days for flowering (NDF), number of pods per plant (X), number of grains per pod (Y), mass of 100 grains (Z) and yield (W). From the obtained results, it was observed that there was a significant difference for the characteristics evaluated in two seasons, and yield was of greater magnitude in first season. In the analysis of joint variance and the Dunnett's test, it was observed that endophytic fungi Acremonium sp. (C20), M. vitigenus (C19) and Simplicillium sp. (C18), when inoculated in cultivars, provided an increase in grain yield by up to 48% compared to control, are showing promise in increasing bean productivity. |

Esses fungos têm sido utilizados com diferentes objetivos, como controle biológico de patógenos, como produtores de compostos orgânicos voláteis e promotores do crescimento de plantas. Assim, o objetivo deste trabalho foi avaliar o efeito de 12 isolados de fungos endofíticos, pertencentes aos gêneros Acremonium, Muscodor e Simplicillium, no desenvolvimento de duas cultivares de feijão (BRSMG Madrepérola e BRSMG União). Para a inoculação dos fungos, as sementes das cultivares foram colocadas em placas de Petri em contato com os fungos até o momento da emissão da radícula. Posteriormente, as sementes foram semeadas em vasos e estes foram mantidos em casa de vegetação até o momento da colheita. Como testemunha foram utilizadas sementes das cultivares sem inoculação. Foram realizados dois experimentos em casa de vegetação, em esquema fatorial 13x2, sendo 12 fungos endofíticos e a testemunha e as duas cultivares de feijão. Os experimentos foram conduzidos em delineamento de blocos completos casualizados, com três repetições. As características avaliadas foram: altura de planta (AP), comprimento de raiz (CR), índice foliar (IF), número de dias para o florescimento (NDF), número de vagens por planta (X), número de grãos por vagem (Y), massa de 100 grãos (Z) e produtividade (W). A partir dos resultados obtidos, observou-se que houve diferença significativa para as características avaliadas nas duas épocas, sendo que na primeira época a produtividade foi de maior magnitude. Na análise de variância conjunta e pelo Teste de Dunnett observou-se que os fungos endofíticos Acremonium sp. (C20), M. vitigenus (C19) e Simplicillium sp. (C18), quando inoculados nas cultivares, proporcionaram um acréscimo na produtividade de grãos em até 48% em relação a testemunha, se mostrando promissores no incremento da produtividade do feijoeiro.Universidade Federal de LavrasPrograma de Pós-Graduação em Genética e Melhoramento de PlantasUFLAbrasilDepartamento de BiologiaSouza, Elaine Aparecida deCardoso, Patrícia GomesMedeiros, Flávio Henrique Vasconcelos deRamalho, Magno Antonio PattoCosta, Maria Cristina MendesHayashibara, Carolina Alessandra de Almeida2017-06-26T16:51:47Z2017-06-26T16:51:47Z2017-06-232017-01-18info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfHAYASHIBARA, C.
