Resumo: The aim of this work was to evaluate the allelopathic effect of extracts of Chrysopogon zizanioides (L.) Roberty and Paspalum millegrana Schrad on germination of lettuce. Aqueous solutions were prepared by maceration and infusion at concentrations of 0, 1, 3 and 5%. In the extracts were measured the osmotic potential (OP), concentration of total soluble sugars (CTSS) and electrical conductivity (EC). The effects of the extracts on the germination of the seeds were evaluated by means of the following parameters: first germination count (FGC), germination (G), germination speed index (GSI) and mean germination time (MGT). Even at low concentrations it was possible to identify allelopathic effect, be it inhibiting or accelerating the growth of the seedlings. Low concentrations of the extract caused seed phytotoxicity at the beginning of the germination process. The aqueous extracts of the vetiver grass and paspalum grass showed allelopathic potential.

O objetivo deste estudo foi avaliar o efeito alelopático de extratos das espécies Chrysopogon zizanioides (L.) Roberty e Paspalum millegrana Schrad em germinação de alface. Nos extratos foi mensurado o potencial osmótico (PO), concentração de açúcares solúveis totais (AST) e condutividade elétrica (CE). Foram avaliados os efeitos dos extratos sobre a germinação das sementes por meio dos seguintes parâmetros: primeira contagem de germinação (PCG), germinação (G), índice de velocidade de germinação (IVG) e tempo médio de germinação (TMG). Mesmo em baixas concentrações foi possível identificar efeito alelopático, seja ele inibindo ou acelerando o crescimento das plântulas. Baixas concentrações do extrato causaram fitotoxicidade das sementes no início do processo de germinação. Os extratos aquosos do capim vetiver e do capim paspalum evidenciaram potencialidades alelopáticas.Iheringia.
