| الوصف: | Long-term survival during dry storage or longevity is a pre-requisite to avoid deterioration, leading to loss of vigor. Longevity is routinely evaluated by the ability to germinate after storage. It increases progressively during seed maturation, after the acquisition of desiccation tolerance. However, the capacity to germinate represents only a part of the success of crop establishment. How seed maturation affects the resistance of several traits, as vigor, associated with seedling establishment, against detenoration was evaluated dunng seed filling and post-abscission phase of soybean BRS 284 seeds. Three newphenological stages between 7.1 and 7.2 (7.1.1, 7.1.2 and 7.1.3) were introduced to capture the rapid increase in seed longevity. Germination speed started to be affected at 7-14 days after storage depending on the stages. The delay on germination increased with maturation from 7.1.3 to dry mature seeds. The time to 50% loss of elongation capacity of both organs during storage was similar to that of loss of germination. Also, it increased steadily dunng seed maturation after mass matunty and harvest matunty stages, highlighting the importance of the late phase of seed maturation for building seed vigor. A sobrevivência durante o armazenamento ou longevidade é pré-requisito para evitar a deterioração, que leva à perda de vigor. A longevidade é rotineiramente avaliada pela habilidade da semente em germinar depois do armazenamento, que aumenta progressivamente durante a maturação depois da aquisição da tolerância à dessecação. No entanto, a germinação representa somente uma parte do processo de estabelecimento da planta. Foi avaliado como a maturação afeta a resistência de várias características, como vigor, relacionadas ao estabelecimento das plântulas em sementes de soja da variedade BRS 284. Três novos estádios entre 7.1 e 7.2 (7.1.1, 7.1.2 e 7.1.3) foram introduzidos para capturar o rápido aumento na longevidade das sementes. O armazenamento induziu uma queda na velocidade de germinação a partir de 7-14 dias de armazenamento, dependendo do estádio, e essa queda diminuiu com a maturação, a partir do estádio 7.1.3. O tempo para perda de 50% na capacidade de alongamento de ambos os órgãos foi similar àquele observado para capacidade de germinação. Além disso, esse tempo aumentou de forma constante durante o período de maturação, demonstrando a importância das fases finais de maturação da semente na construção do vigor. |
