Resumo: | Weed cause substantial reduction in yields of large crops by competing for light, water, nutrients and space. Allelopathic plant extracts have been used successfully in the management of these plants. Maria pretinha (Solanum americanum) is a weed that has allelopathic effects on other plants. Therefore, the present research aimed to evaluate the possible allelopathic effect of aqueous extracts from the leaves of maria pretinha on the germination and initial growth of maize (Zea mays). The experiments were conducted in the Botany Laboratory located at Cesumar University - UNICESUMAR, in a BOD-type incubation chamber, at 25°C and 12-hours photoperiod, for six days. The raw aqueous extract was obtained through the maceration of the leaves in water and the other concentrations were diluted to reach each specific treatment. The experimental design used was entirely randomized with four repetitions of each treatment. The results were submitted to variance analysis and the means compared by the Scott-Knott test at 5% significance. It was observed that the maria pretinha had a negative allelopathic effect on the length of the maize roots, however, it did not affect the germination of this plant. |

Extratos alelopáticos vegetais têm sido utilizados com sucesso no manejo dessas plantas. A maria pretinha (Solanum americanum) é uma planta daninha que apresenta efeitos alelopáticos sobre outros vegetais. Desta maneira, o presente trabalho teve como objetivo avaliar o possível efeito alelopático de extratos aquosos das folhas de maria pretinha sobre a germinação e crescimento inicial do milho (Zea mays). Os experimentos foram conduzidos no Laboratório de Botânica, localizado na Universidade Cesumar – UNICESUMAR, em câmera de incubação tipo BOD, a 25°C e fotoperíodo de 12 horas, durante seis dias. O extrato aquoso bruto foi obtido através da maceração das folhas em água e as demais concentrações, foram diluídas para chegar em cada tratamento específico. O delineamento experimental utilizado foi inteiramente casualizado com quatro repetições de cada tratamento. Os resultados foram submetidos a análise de variância e as médias comparadas pelo teste Scott-Knott a 5% de significância. Observou-se que a maria pretinha apresentou efeito alelopático negativo sobre o comprimento das raízes de milho, no entanto, não afetou a germinação desta planta.UNIVERSIDADE CESUMARBrasilUNICESUMARBIDO, Graciene de SouzaFILHO, Edison SchimidtZULIANI, Aline Maria Orbolato GonçalvesBIDO, Graciene de SouzaOLIVEIRA, Jair TrizottiPOLLI, Lucas Sisti Michelan de2021-02-12T14:24:36Z2021-02-122021-02-12T14:24:36Z2021-02-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfOLIVEIRA, Jair Trizotti; POLLI, Lucas Sisti Michelan de.
