Resumo: | Sunn hemp (Crotalaria spectabilis) is widely used for soil correction and cover, but it is still necessary to know the characteristics that influence the storage of its seeds. This study aimed to evaluate the physiological quality of sunn hemp seeds under uncontrolled environmental conditions and in acclimatization chamber. A completely randomized experimental design was used, with four replicates, in subplots evaluated in different periods. Freshly harvested seeds and seeds at 90, 180 and 270 days of storage were evaluated for germination, first germination count, germination speed index, seedling emergence in the field, accelerated aging, cold test and seedling growth. The environment and storage time significantly influenced the seed germination and vigor. The seeds showed a high physiological performance for both the environmental conditions, maintaining the ability to produce normal seedlings up to approximately 150 days of storage, deteriorating afterwards, although without losing their germination capacity up to 270 days of storage. KEYWORDS: Crotalaria spectabilis, seed dormancy, seed vigor. |

KEYWORDS: Crotalaria spectabilis, seed dormancy, seed vigor.A crotalária (Crotalaria spectabilis) é amplamente utilizada na correção e cobertura do solo, mas ainda é necessário determinar as características que influenciam no armazenamento de suas sementes. Objetivou-se avaliar a qualidade fisiológica de sementes de crotalária durante o armazenamento, em condições de ambiente não controlado e em câmara climatizada. O delineamento experimental foi o inteiramente casualizado, com quatro repetições, em subparcelas divididas no tempo. As avaliações foram realizadas em sementes recém-colhidas e aos 90, 180 e 270 dias de armazenamento, por meio de germinação, primeira contagem de germinação, índice de velocidade de germinação, emergência de plântulas a campo, envelhecimento acelerado, teste de frio e crescimento de plântulas. O ambiente e o tempo de armazenamento influenciaram significativamente na germinação e vigor das sementes. As sementes apresentaram elevado desempenho fisiológico nas duas condições de ambiente, mantendo a capacidade de produzir plântulas normais até por volta de 150 dias de armazenamento, deteriorando-se posteriormente, porém, sem perder a capacidade de germinação até 270 dias de armazenamento.
