Resumo: The use of plants as surface coverage or incorporated is a practice used for a long time in order to provide organic matter for the soil, as it improves many factors such as edaphological, chemical and physical characteristics, which leads to a reduction in fertilizer costs. However, many plant species release allelochemicals that can beneficially or detrimentally interfere with the germination and development of other plants. The yellow ipe (Tabebuia serratifolia (Vahl) G. Nichols) has allelopathic potential and can influence the productivity of agricultural systems. Vegetables are widely used in bioassays due to their short life cycle and sensitivity to changes in the environment. Therefore, the objective of this work was to evaluate the allelopathic effect of Tabebuia serratifolia (Vahl) G. Nichols on the initial growth of lettuce (Lactuca sativa L.) and kale (Brassica oleracea L.). The experiment was carried out in Maringá-PR in pots, in the presence or absence of yellow ipe leaves as incorporated or superficial. The experimental design was carried out in a completely randomized manner, with five treatments and three replications of each. Data were evaluated by analysis of variance and means between different treatments compared by Scott Knott test at 5% significance. There was no allelopathic effect of ipe on the initial growth of lettuce and cabbage. However, the results may have been persuaded due to bad weather, such as frost during the experiments. Therefore, it is necessary to carry out more studies to confirm the data.

Entretanto, muitas espécies de plantas liberam aleloquímicos que podem interferir de forma benéfica ou prejudicial na germinação e desenvolvimento de outras plantas. O ipê amarelo (Tabebuia serratifolia (Vahl) G. Nichols) apresenta potencial alelopático e pode influenciar a produtividade de sistemas agrícolas. As hortaliças são muito utilizadas em bioensaios devido ao ciclo de vida curto e sensibilidade a alterações no meio. Portanto, o objetivo deste trabalho foi avaliar o efeito alelopático da Tabebuia serratifolia (Vahl) G. Nichols sobre o crescimento inicial da alface (Lactuca sativa L.) e couve (Brassica oleracea L.). O experimento foi conduzido em Maringá- PR em vasos, na presença ou ausência de folhas de ipê amarelo como incorporadas ou superficial. O delineamento experimental sucedeu de forma inteiramente casualizada, com cinco tratamentos e três repetições de cada. Os dados foram avaliados por análise de variância e as médias entre os diferentes tratamentos comparados pelo teste de Scott Knott a 5% de significância. Não foi verificado efeito alelopático do ipê sobre o crescimento inicial de alface e couve. Entretanto, os resultados podem ter sido persuadidos devido a intemperes ocorridas, como geada durante os experimentos. Sendo assim, é necessário realizar mais estudos para comprovar os dados.UNIVERSIDADE CESUMARBrasilUNICESUMARBIDO, Graciene de SouzaBIDO, Graciene de SouzaSANCHES, Rafael EgeaMARTELÓCIO, Alan CarlosMONTE, Geovana Izabela do2021-12-21T16:48:08Z2021-12-212021-12-21T16:48:08Z2021-12-21info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMONTE, Geovana Izabela do.
