Resumo: | The objective of the present research was to determine the allelopathic potential of Ipomoea fistulosa plants on germination and growth of seedlings. In laboratory, lettuce and tomato seeds were placed to germinate in the presence of water or Ipomoea fistulosa leaf extract, in the concentrations of 5, 10 e 15% (p/v). In greenhouse, seeds were placed to germinate in trays containing Plantmax® substrate and Plantmax® substrate + Ipomoea fistulosa dry leaf residue, at 3% (w/w). The aqueous extract inhibited germination, raised the mean germination time of the seeds and reduced the radicle and hypocotyl growth in all used concentrations. In greenhouse, the plant height, leaf number, and dry mass accumulation also were reduced in the presence of the leaf residue in the substrate. The results suggest the presence of allelochemicals in Ipomoea fistulosa and demonstrate the highest sensitivity of lettuce that tomato to these compounds. |

Em laboratório, sementes de alface e de tomate foram colocadas para germinar na presença de água ou extratos de folhas de Ipomoea fistulosa, nas concentrações de 5, 10 e 15% (p/v). Em casa-de-vegetação, as sementes foram colocadas para germinar em bandejas, contendo o substrato Plantmax® e o substrato Plantmax® + resíduo de folhas secas de Ipomoea fistulosa, na proporção 3% (p/p). O extrato aquoso inibiu a germinação e elevou o tempo médio de germinação das sementes, além de reduzir o crescimento da radícula e hipocótilo em todas as concentrações utilizadas. Em casa-de-vegetação, a altura da planta, o número de folhas, o acúmulo de massa seca das plantas também foram reduzidos na presença dos resíduos de folhas no substrato. Os resultados sugerem a presença de aleloquímicos em Ipomoea fistulosa e demonstram maior sensibilidade da alface a esses compostos, quando comparada ao tomate.Universidade Estadual de Maringá2008-05-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/355310.4025/actasciagron.v30i3.3553Acta Scientiarum.
