Resumo: | Trifolium polymorphum and T. argentinense (Leguminosae) are two amphicarpic forage species native to the natural pastures of the southern half of Rio Grande do Sul, southern Brazil. Information about seed production in both species is scarce. In the present work we evaluated the number of inflorescences and the production of aerial seeds in T. polymorphum and T. argentinense in a protected environment and without access of pollinators. T. polymorphum plants produced significantly more inflorescences and seeds (63.15 and 8.94) than those of T. argentinense (24.84 and 1.05), respectively. The low seed production in a protected environment and without access to pollinators suggests the need for mechanical stimulation to ensure pollination, usually performed by insects to form seeds. This information can be used to plan future experiments where T. polymorphum and T. argentinense have free access to pollinators to obtain a higher seed production. |

Trifolium polymorphum e T. argentinense (Leguminosae) são duas espécies forrageiras anficárpicas nativas das pastagens naturais da metade sul do Rio Grande do Sul, no sul do Brasil. As informações a cerca da produção de sementes em ambas espécies são escassas. No presente trabalho nós avaliamos o número de inflorescências e a produção de sementes aéreas em T. polymorphum e T. argentinense em ambiente protegido e sem acesso de polinizadores. As plantas de T. polymorphum produziram significativamente mais inflorescências e sementes (63,15 e 8,94) que aquelas de T. argentinense (24,84 e 1,05), respectivamente. A baixa produção de sementes em ambiente protegido e sem acesso a polinizadores sugere a necessidade de estimulação mecânica para assegurar polinização, normalmente realizada por insetos, para formar sementes. Essas informações podem ser usadas para planejar futuros experimentos onde T. polymorphum e T. argentinense tenham livre acesso a polinizadores para obtenção de uma maior produção de sementes.Departamento de Diagnóstico e Pesquisa Agropecuária.
