Resumo: | Trifolium polymorphum Poir. is a legume of natural pastures that combines amphicarpy with vegetative reproduction, but with little morphoagronomic information in populations of southern Brazil. In this study, plant height and diameter, number of primary stolons, dry matter, number of inflorescences, number of flowers per inflorescence, number of flowers with legume with seeds, number of flowers without legume or with legume without seeds, seed production, number and dry weight of storage roots were evaluated in populations of T. polymorphum. Little variation was observed for most characteristics, including low dry matter and aerial seed production. There were positive correlations between plant height and dry matter (r = 0.44), plant diameter and dry matter (r = 0.43), number of inflorescences and number of flowers per plant (r = 0.98) and number of inflorescences and seed production (r = 0.84). T. polymorphum presented low dry matter yield, however, the reproductive versatility of the species with the amphicarpic condition combined with vegetative propagation are mechanisms that allow the species to increase its frequency and contribution in natural pastures. |

Nesse estudo foram avaliados altura e diâmetro das plantas, número de estolões primários, matéria seca, número de inflorescências, número de flores por inflorescência, número de flores com legumes com sementes, número de flores sem legumes ou com legumes sem sementes, produção de sementes, número e peso seco das raízes de reserva em populações de T. polymorphum. Pouca variação foi observada para a maioria das características, incluindo baixa produção de matéria seca e de sementes aéreas. Ocorreram correlações positivas entre altura da planta e matéria seca (r = 0,44), diâmetro da planta e matéria seca (r = 0,43), número de inflorescência e número de flores por planta (r = 0,98) e número de inflorescências e produção de sementes (r = 0,84). O T. polymorphum apresentou baixa produção de matéria seca, no entanto, a versatilidade reprodutiva da espécie com a condição anficárpica aliada a propagação vegetativa são mecanismos que possibilitam à espécie aumentar a sua frequência e contribuição nas pastagens naturais.Departamento de Diagnóstico e Pesquisa Agropecuária.
