Resumo: | Randia ferox (Cham. & Schlecht.) DC. is a small tree of ornamental value. It is native in Brazil from Minas Gerais to Rio Grande do Sul State. The objective of this work was evaluate the seeds germination behavior at harvest time and during 15 months of storage in dry chamber conditions, by submitting two seeds lots to seed moisture determination and germination, emergence in greenhouse and speed of germination and emergence tests. At harvest time the seed moisture content was 41.6% and the seeds presented 96% of germination. After two months of storage the seeds moisture storage, the dry161 reduced to 11,6% (average), without significantly reduction chamber temperature and humidity conditions (17oC±2oC e in ~ = 45%UR) germination were percentages. propitious to During preserve the seeds longevity for fifteen months. |

Arvoreta de valor paisagístico, nativa no Brasil de Minas Gerais ao Rio Grande do Sul. Objetivou-se avaliar o comportamento germinativo de sementes de Randia ferox, após a coleta e durante 15 meses de armazenamento em câmara seca, através das determinações de teor de água, percentagem e velocidade de germinação em laboratório e emergência em casa de vegetação, utilizando-se dois lotes de sementes. Na coleta, as sementes apresentaram médias de teor de água de 41,6%, e 96% de germinação. Após dois meses em câmara seca houve redução do teor de água para 11,6% (média), condições sem de temperatura redução significativa e umidade da (17oC±2oC percentagem e = ~ 45%UR) de germinação promoveram em relação a manutenção à coleta. da Durante germinação o armazenamento, inicial, mostran- as do-se adequadas para conservação da longevidade das sementes durante quinze meses.
