          Abstract

          Foram estudados os efeitos alelopáticos produzidos por cinco espécies vegetais: as gramíneas Avena sativa L., e Lolium multiflorum Lamb.; e as leguminosas Vicia sp., Mediaago sativa L. e Trifolium repens L. Canteiros isolados foram preparados, adubados e semeados de acordo com as recomendações técnicas usuais. Nos resultados obtidos observou-se alta incidência de invasoras nos canteiros de Trifolium repens L. e Medicago sativa L., contrastando com os canteiros de Avena sativa L. e Lolium multiflorum Lamb., onde poucas foram as espécies encontradas; enquanto o canteiro de Vicia sp. manteve posição intermediária. Com base nos dados obtidos, pode-se recomendar as duas gramíneas como cultura de cobertura com propriedades alelopáticas, assim como a Vicia sp. quando desejar-se além da redução das plantas invasoras, matéria orgânica para incorporação.

          The alellopathic effects produced by five vegetables species: Avena sativa L., Lolium multiflorum Lam., Vicia sp., Medicago sativa L. and Trifolium repens L. were studied as to their effect on weeds. Individual plots were prepared, fertis. A high weed incidence was noted in the plots of Trifolized and sowed according to the usual recomendationlium repens L. and Medicago sativa L.; in the plots of Avena sativa L. and Lolium multiflorum Lam. , few weed specimens were found; the plot of Vicia sp. maintained an intermediate position. Based on the data obtained it is possible to recommend the two grass species as alellopathic plants to cover the soil. Vicia sp. is indicated when besides the reduction of weed plants, organic matter is desired for incorporation.
