Resumo: The present study aimed to evaluate effects of different storage conditions on the castor bean seed cultivar IAC-226 quality, stored for 12 months. For this purpose, seeds were stored in different environment and packaging conditions: in a cold chamber and conventional storage, using multiwall Kraft paper and in no vacuum and vacuum plastic packages at 1 atm; as well as under cryopreservation storage (-196 °C). Seed quality was evaluated before and after 4, 8 and 12 months of storage by germination tests, first count of germination, emergence percentage, emergence speed index and determination of changes in catalase (CAT) and superoxide dismutase (SOD) enzyme systems. Cryopreservation (-196 °C) is efficient in maintaining the physiological quality of castor bean cultivar IAC-226 for 12 months. The enzyme catalase stands out as a marker of castor seed deterioration during storage.

Para isso, as sementes foram armazenadas em diferentes ambientes e tipos de embalagens: em câmara fria e armazém convencional, utilizando embalagens papel Kraft multifoliado e plástico com e sem acondicionamento a vácuo a 1 atm; e também armazenamento sob criopreservação (-196 °C). A qualidade das sementes foi avaliada antes e após 4, 8 e 12 meses de armazenamento pelos testes de geminação, primeira contagem de germinação, porcentagem de emergência, índice de velocidade de emergência e pela determinação das alterações nos sistemas enzimáticos catalase (CAT) e superóxido dismutase (SOD). A criopreservação (-196 °C) é eficiente na manutenção da qualidade fisiológica de sementes de mamona cultivar IAC-226 por 12 meses. A enzima catalase se destaca como um marcador da deterioração de sementes de mamona durante o armazenamento.Associação Brasileira de Tecnologia de Sementes (ABRATES)2018-08-30T11:25:47Z2018-08-30T11:25:47Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSANTOS, H.
