Abstract: roSângela CaldaS mundim 4 , Juliano gomeS Pádua 5 .RESUMO -Dentre os processos que precedem a conservação em longo prazo, a secagem tem papel fundamental, uma vez que o conteúdo de água das sementes afeta diretamente a sua longevidade. Os objetivos desse trabalho foram pesquisar o efeito da umidificação prévia das sementes após ultrassecagem em diferentes teores de água sobre a qualidade fisiológica de sementes de girassol. Sementes com conteúdo inicial de água de 4,7% foram embebidas previamente até conteúdo … Show more

“…Results were submitted to analysis of variance, qualitative averages were compared by the Scott-Knott test, and quantitative data were submitted to regression at 5% probability (Ferreira, 2011 Results and Discussion Figure 1 shows the drying curve for coffee seeds submitted to rapid drying on silica gel until reaching different water contents. Silica gel retains the water molecules on the surface of its pores by means of physical adsorption (José et al, 2009). However, it is observed that the average drying rate decreases as the seed water content decreases.…”

“…Ela retira a umidade por meio da adsorção física da água, que tem suas moléculas retidas à superfície dos poros do dessecante (José et al, 2009). Normalmente, a sílica gel tem capacidade de adsorção de água de, no máximo, 30% de seu próprio peso, mas pode ter sua capacidade de adsorção regenerada (José et al, 2011).…”

“…The fast drying of tobacco seeds after priming is more efficient for maintaining physiological quality and vigor Journal of Seed Science, v.40, n.4, p.415-421, 2018 of seeds when compared to the slow drying (Table 5B). According to José et al (2009), among the processes that precede seed conservation, drying has an essential role. However, depending on how it is conducted, it can damage seeds, leading to a reduction in their physiological quality.…”
