Summary
Objetivou-se, avaliar os efeitos do extrato etanólico de própolis (EEP) sobre a incidência de cercosporiose e o desenvolvimento de mudas de cafeeiro cv. ‘Catuaí vermelho’. O delineamento utilizado foi em blocos casualizados com cinco repetições e dez plantas/parcela. O esquema experimental foi em fatorial 4 x 6. O primeiro fator foram quatro EEPs, confeccionados com diferentes porcentagens de própolis bruta (PB) na composição (1, 4, 7 e 10% de PB e o restante com etanol a 92%). O segundo fator foi a diluição dos EEPs em água: (0; 0,5; 1,0; 1,5; 2,0 e 2,5%). A área abaixo da curva de progresso da cercosporiose foi reduzida de forma quadrática com a aplicação de EEP, independentemente da proporção de própolis bruta adicionada ao extrato. Observou-se, com a curva de comportamento da cercosporiose que, as concentrações 1,0; 1,5 e 2,0% de EEP tiveram menor incidência, 2,5% intermediária e a testemunha e 0,5% de EEP tiveram a maior incidência. Verificou-se ainda que o EEP aumentou a área foliar e o número de folhas/parcela de forma quadrática. O aumento no desenvolvimento das mudas foi atribuído a presença de nutrientes na própolis e a redução na incidência da cercosporiose com aplicação de EEP. O controle da cercosporiose pode ser atribuído a presença de nutrientes, a formação de uma camada de impedimento sobre as folhas com a cera da própolis e efeito indutor de resistência da própolis.
Summary translation
The objective of this study was to evaluate the effect of ethanolic extract of propolis (EEP) on incidence of brown eye spot and development of coffee cv. ‘Catuaí vermelho’. The experiment was arranged in a randomized block design with five replications and ten plants per plot. The experiment was a factorial scheme 4 x 6. The first factor EEP were made with four different percentages in the composition of raw propolis (1, 4, 7 and 10% of raw propolis with ethanol 92%). The second factor was the dilution of the EEP in water (0, 0.5, 1.0, 1.5, 2.0 and 2.5%). It was found that the EEP increased leaf area and leaf number per plot and growing quadratically. It was observed, with the curve of brown eye spot behavior that concentrations 1.0, 1.5 and 2.0% EEP had lower incidence, 2.5% intermediate and the control and 0.5% EEP had the highest incidence. The area under the curve of progress of brown eye spot leaf spot reduced quadratically with the implementation of EEP regardless of the proportion of the raw propolis extract. The increase in seedling growth was attributed to the presence of nutrients in propolis and reduced incidence of brown eye spot with application of EEP. The control of brown eye spot was awarded to the presence of nutrients, the formation of a layer of impediment on the sheets with wax and propolis resistance inducing effect of propolis.
