O feijoeiro comum é uma cultura de grande importância alimentar, econômica e social, em termos de produção e consumo, é uma leguminosa herbácea, com ciclo em torno de 95 dias, a maioria das cultivares utilizadas para o cultivo no mercado brasileiro expressa grande variabilidade genéticas quanto ao início de florescimento e a duração total do ciclo. Diante disso, objetivou-se com este trabalho avaliar a caracterização morfoagronômica de genótipos de feijoeiro comum quanto à precocidade de cultivo. O experimento foi conduzido na EMAPER, no município de Cáceres-MT, adotando o delineamento experimental em blocos ao acaso com três repetições, avaliando 58 genótipos de feijão comum. As parcelas foram compostas por quatro linhas de 4 m, com espaçamento de 0,5 m entre linhas. As características avaliadas foram o número de dias para o florescimento e ciclo de cultivo, os dados foram submetidos à análise de variância e a comparação das medias pelo teste de agrupamento Scott-Knott a 1% de probabilidade. A divergência genética foi estimada método de otimização de Tocher e hierárquico UPGMA, baseada na Distância Generalizada de Mahalanobis utilizando o programa computacional GENES. Pode-se concluir que existe variabilidade genética entre os genótipos de feijão comum avaliados, e os genótipos 3 (BG-UNEMAT-11) e 57 (TB 02-23) apresentaram menor número de dias para florescimento (31 dias) e menor ciclo da cultura (73 a 82 dias), sendo os mais indicados para programas de melhoramento genético visando precocidade.
Banana is one of the most consumed fruits in the world, with high nutritional value, unparalleled flavor and affordable price. However, banana can be affected by numerous diseases, and Panamanian malaria is a pathogen caused by Fusarium oxysporum, with great impact on the culture. In order to find efficient and sustainable methods to control this phytopathogen, the present work aims to evaluate the antifungal activity of different vegetable oils. The experiment was carried out in the Microbiology Laboratory of the State University of Mato Grosso, Alta Floresta - MT, installed in a completely randomized design with 5 treatments, 4 vegetable oils (melaleuca, eucalyptus, citronella, mint) and the control Fusarium oxysporum disk) with 5 replicates. The measured essential oils were incorporated into the BDA culture medium at the concentration of 0.6% and the treatments were poured into Petri dishes. Subsequently, a 9 mm disk of pure phytopathogens was inserted into each plate. The plates were redirected to BOD, with a temperature of 25C ° and photoperiod 12/12 hours. The evaluation began after 24 hours, with measurements of the diameter of the colonies made up to the ninth day. These data were used in the calculation of mycelial growth rate index (IVCM) and percentage of growth inhibition (PIC) and finally submitted to analysis of variance, being observed that the oils have different effects between them. Thus, after the test of comparison of means, it was observed that the oils of melaleuca and eucalyptus are similar with the control, that is, they are not efficient in the control of the fungus in question since they present high IVCM. Citronella and mint oils demonstrated efficacy in the control of the pathogen, with a low IVCM value and high PIC value
