Influência do tipo de embalagem na qualidade fisiológica de sementes de milho crioulo

Abstract: RESUMO -Objetivou-se com este trabalho avaliar a qualidade fisiológica de sementes de seis variedades de milho submetidas ao armazenamento em embalagens plásticas a vácuo e em sacos de pano. Para tanto, foram realizadas avaliações do teor de água, germinação, primeira contagem de germinação, emergência, índice de velocidade de emergência, comprimento de parte aérea e massa seca de plântulas. Utilizou-se o delineamento inteiramente casualizado, com os tratamentos arranjados em esquema 6x4x2 (variedades x tempos… Show more

“…The farmers may use anything from PER bottles to zinc silos for seed storage, and, therefore, they may not provide an ideal environment for seed storage, resulting in decreased seed germination. Without the ideal storage environment, the seed may be exposed to high humidity and determinal temperatures, which when combined with the type of packaging used (generally permeable or semipermeable) has a great influence seed conservation and reduced germination (Antonello et al, 2009). Differences in physiological quality between varieties and seed lots can be attributed not only to the genotype but also to the effects of environmental conditions prevailing during the maturation and harvesting phase (Aguero et al, 1997).…”

“…As sementes crioulas utilizadas na agricultura familiar nordestina advêm de diversas variedades e são importantes para os pequenos agricultores, pois representam a sua base alimentar e cultural, o que torna fundamental a manutenção da qualidade fisiológica das sementes durante o armazenamento nas casas de sementes (ANTONELLO et al, 2009). Tendo em vista a importância das sementes crioulas, o objetivo do presente trabalho foi avaliar a qualidade fisiológica, em termos de germinação e vigor, de sementes crioulas de feijão-caupi provenientes de cinco genótipos comumente utilizados do estado do Ceará, através dos testes de germinação, índice de velocidade de germinação e condutividade elétrica.…”

“…When evaluating vigour by the dry weight of the seedlings, it was found that there was a decrease in dry weight over nine months of storage, and an increase in the 12th month, for seeds stored in controlled environments (dry cold room, fridge and freezer) According to Antonello et al (2009) this result does not reflect the usual behaviour of stored seeds, where it is expected that evaluation of the characteristics of the seedlings at the end of the storage period should show a decrease caused by the loss of seed vigour over time. In the natural environment, the seedlings showed a reduction in dry weight by the third month of storage, and a sharp drop at six months.…”
