Resumo: This study evaluated the allelopathic potential of leaf and root extracts of Lafoensia glyptocarpa Koehne on seed germination and the growth of seedlings and sesame (Sesamum indicum L.) metaxylem cells. We found that the leaf and root extracts of L. glyptocarpa changed in sesame seed germination and seedling growth, as well as changes in the primary root and decreased size and number of metaxylem cells. Leaf extracts were also obtained with hexane, dichloromethane, ethyl acetate, acetone, and methanol, and tested when developing wheat coleoptiles, and the last four showed activity. By subfractioning the ethyl acetate extract,which was the most promising, inhibitory activity ceased for subfractions, and the presence of synergism was subsequently found between them.

A partir dos resultados, verifi cou-se que os extratos de folhas e raízes de L. glyptocarpa causaram alterações na germinação das sementes e no crescimento das plântulas de gergelim, além de alterações na raiz primária e diminuição no tamanho e número de células do metaxilema. Foram também obtidos extratos foliares com hexano, diclorometano, acetato de etila, acetona e metanol, e testados sobre o desenvolvimento de coleóptilos de trigo, sendo que os quatro  últimos apresentaram atividade. Com o sub-fracionamento do extrato de acetato de etila, que se apresentou como o mais promissor, cessou a atividade inibitória para as sub-frações, sendo posteriormente verifi cada a presença de sinergismo entre elas.Iheringia.
