Resumo: | "Cagaita" is a native species of "Cerrado" savannah, with very irregular seed germination. The objective of this study was to evaluate the effect of harvest type and seed size on the germination rate and vigor of Cagaita seeds. The experiment was carried out in a 2 x 3 factorial completely randomized design with six treatments: two harvest types (from the tree and on the ground) and three seed sizes (large, medium, small). Germination started fourteen days after planting and ended in the 60th day. The germination and seedling early growth were described and illustrated by drawings. Large seeds harvest on the ground present lower humidity, greater seedling vigor, and higher fresh matter. There were not found significant differences for germination rate treatments. It was concluded that Cagaita seeds should be obtained from ripe fruits on the ground. Large seeds from those fruits showed to be more vigorous. In seedling production and germination tests the separation of seeds by size may be applied for obtention of seed lots with uniform vigor. KEY-WORDS: Seed, seedling; vigor; morphology; savannah. |

A Cagaita é uma espécie nativa do cerrado de usos diversos. Contudo, a germinação de suas sementes tem apresentado grande desuniformidade. Este estudo objetivou avaliar os efeitos da forma de coleta dos frutos e do tamanho das sementes sobre a germinação e vigor. O delineamento experimental foi do tipo fatorial 2 x 3, inteiramente casualizado, com dois tipos de coleta dos frutos (na planta e no solo) e três tamanhos das sementes (grandes, medianas e pequenas). A germinação iniciou-se quatorze dias após a semeadura, estabilizando aos sessenta dias após o seu início. As fenofases da germinação e do crescimento inicial das plântulas foram descritas e ilustradas. As sementes grandes coletadas no solo apresentaram menores teores de água e plântulas mais vigorosas, com maior acúmulo de massa fresca. Entretanto, os tratamentos não apresentaram diferenças significativas na germinação. Concluiu-se que as sementes de cagaita devem, preferencialmente, ser obtidas de frutos maduros caídos sobre a superfície do solo, e que sementes grandes obtidas de frutos coletados no solo são mais vigorosas. No processo de produção de mudas e em testes de germinação, a separação das sementes em diferentes tamanhos pode ser utilizada para obtenção de sementes com vigor uniforme.
