Resumo: The main factors affecting seed storage capacity are the seed water content and temperature. The higher are these values, the higher are the deterioration rates. There are mathematical models that allow to estimate the lifespan of seeds in storage, whenever the values of both factors are provided. However, for some species, especially these native from tropical forest regions, these equations are not so efficient. In this work we analysed the deterioration rates of desiccation-tolerant (Erythrina speciosa) and desiccation-sensitive (Eugenia spp.) seeds, in order to obtain new data to understand the difference in the deterioration rates under different environmental conditions. The results evidenced great variation in the responses. Therefore, more studies are needed, especially for seeds that are sensitive to desiccation.

Quanto mais altos esses valores, maiores as taxas de deterioração. Existem modelos matemáticos que propõem estimar a vida útil das sementes em armazenamento, uma vez que esses dois fatores são fornecidos. No entanto, para algumas espécies, especialmente em florestas nativas de regiões tropicais, essas equações não são tão eficientes. Neste trabalho, analisamos as taxas de deterioração de sementes tolerantes (Erythrina speciosa) e sensíveis (Eugenia spp.) à dessecação para termos mais elementos na busca do entendimento dessas diferenças na taxa de deterioração em diferentes condições ambientais. Os resultados mostraram grandes variações nas respostas, evidenciando a necessidade de mais estudos, principalmente quando as sementes são sensíveis à dessecação.Iheringia.
