“…In fact, what is confirmed in the analysis of means of genotype UFV19. Pádua et al (2010) and Pereira et al (2013) has related the larger size of the seeds with the best seedling development, indicating superiority of large seeds in the formation of the stand (Table 3). These findings make sense in the observation that the reduction in reserves of seeds (RRS) correlates with the relative yields of dry matter (RYDM).…”

“…According to this observation, a correlation between the average length of hypocotyl (AHL) and the relative length of seedling, relative dry matter of seedling and relative yield of dry matter (RLS, SDMW, RYDM) was found. According to Pereira et al (2013), hypocotyl is more sensitive than the radicle under water stress; therefore it is important to observe its development, as it is more sensitive to changes caused by the environment. However, the correlation between the relative lengths of hypocotyl, radicle and seedling points to the plausible fact of maintaining the proportions in the measurements of seedlings in different cultivars.…”

“…For the remaining dry matter of the cotyledons (RDWC), the pairs of cotyledons reserved during the length measurement procedure of the seedlings were placed to dry in an oven at 80 ± 1 °C for 24 hours and then weighed. In order to match all weights, these values were also estimated for 50 pairs of cotyledons, a procedure adapted from the methodologies presented by Soltani et al (2002) and Soltani et al (2006).…”

“…Based on the literature, seed lots with high quality and vigor have higher seedling and are able to accumulate more dry matter (Schuab et al, 2002;Henning et al, 2010), and, in general, larger seeds have a better physiological quality (Pereira et al, 2013). These findings may be related to the fact that high vigor seeds have a higher starch content, soluble proteins and sugars, and also greater capacity to mobilize reserves during the germination period (Henning et al, 2010).…”

-Physiological quality and vigor of the seeds comprise properties that determine a high level of activity and performance during germination and seedling emergence, having a direct relation with the establishment of the stand of a crop. In this context, the assessment of seedling development, including the analysis of the seed reserves mobilization are a reliable method to investigate the physiological potential of seed lots. In this preliminary study, the aim was to investigate the dynamics of seed reserves mobilization of a sample of soybean commercial cultivars. By means of the seedling length bioassay and weight of dry matter of seeds, cotyledons, hypocotyls and radicles, information on the reserves mobilization during the germination process was obtained. Data were subjected to analysis of variance and Scott and Knott test, and afterwards, phenotypic correlations between traits were obtained. The results have shown that the dry matter of seeds, reserves reduction of seeds and dry matter of seedlings are positively correlated, and thus, seeds containing more reserves may be more effective during the early development of seedlings. In contrast, reserve reduction of seeds and conversion efficiency of the seeds reserves in the dry matter of seedlings are negatively correlated.Index terms: Glycine max (L.)

Dinâmica de reservas das sementes de soja durante o desenvolvimento de plântulas de diferentes cultivares comerciaisRESUMO -Qualidade fisiológica e vigor compreendem propriedades das sementes que determinam alto nível de atividade e desempenho durante a germinação e emergência das plântulas, tendo relação direta com o estabelecimento do estande de uma lavoura. Neste contexto, a avaliação do desenvolvimento das plântulas, incluindo análise da mobilização de reservas das sementes pode se constituir em um método confiável para investigação do potencial fisiológico de lotes. Neste estudo preliminar, objetivou-se investigar a dinâmica de reservas em sementes de cultivares comerciais de soja. Por meio do teste de comprimento de plântulas e peso de massa seca de sementes, cotilédones, hipocótilos e radículas foram obtidas informações sobre a mobilização de reservas durante o processo de germinação. A massa seca de sementes, redução de reservas de sementes e massa seca de plântulas estão positivamente correlacionados entre si, e, logo, sementes contendo mais reservas podem apresentar maior vigor durante o desenvolvimento inicial de plântulas. Em contrapartida, redução de reserva de sementes e eficiência na conversão de reservas das sementes em massa seca de plântulas são negativamente correlacionadas.Termos para indexação: Glycine max (L.)

“…Based on the literature, the seed lots with high germination and vigor have larger seedlings that are able to accumulate more dry matter Pereira et al, 2013;Pereira et al, 2015). These discoveries may be related to the fact that high vigor soybean seeds have not only greater physical integrity (as long as the drying operations were well performed (Afrakhteh et al, 2013) but also higher contents of starch, proteins, and soluble sugars and greater ability to mobilize reserves during the germination period .…”

-Drying of seeds reduces their moisture content to levels appropriate for storage. However, care in the temperatures applied in the process is necessary to avoid damage to the seeds that are dried. The aim of this study was to evaluate the effect of different drying temperatures and storage on the growth of soybean seedlings. Harvested with a moisture content of approximately 23% (w.b.), the seeds were dried at different temperatures (40, 50, 60, 70, and 80 °C) until reaching moisture content of 12.5 ± 0.7% (w.b.), and they were subsequently stored for 180 days in an environment without climate control. A germination test and evaluations of seedling performance were carried out every 45 days, determining the full length of the seedling and hypocotyl and root lengths, along with their respective dry matter weights. The results showed that: a) the increase in the temperature of drying air affects the physiological quality of soybean seeds, and this effect is accentuated over time, especially on root length; and b) the air temperature of 40 °C can be recommended for drying of soybean seeds in association with the storage time of 180 days under storage conditions without climate control.Index terms: Glycine max L., germination, seed vigor, post-harvest.Temperaturas de secagem e armazenamento de sementes no crescimento de plântulas de soja RESUMO -A secagem de sementes permite reduzir o teor de água a níveis adequados para o armazenamento. Porém, cuidados com as temperaturas aplicadas no processo são necessários para evitar danos às sementes submetidas à secagem. O trabalho foi realizado com o objetivo de avaliar o efeito de diferentes temperaturas de secagem e do armazenamento sobre o crescimento de plântulas de soja. As sementes foram colhidas com aproximadamente 23% de teor de água, e submetidas a diferentes temperaturas de secagem (40, 50, 60, 70 e 80 °C) até atingirem 12,5 ± 0,7% (b.u.), sendo posteriormente armazenadas, em ambiente não controlado, durante 180 dias. A cada 45 dias foi realizado o teste de germinação e as avaliações referentes ao desempenho de plântulas, determinando-se os comprimentos total, do hipocótilo e da raiz, e ainda verificando suas respectivas massas de matéria seca. Com base nos resultados pôde-se concluir que: a) o aumento da temperatura do ar de secagem afeta a qualidade fisiológica das sementes, sendo esse efeito potencializado com o tempo de armazenamento, principalmente sobre o comprimento da raiz; b) a temperatura do ar de 40 °C pode ser recomendada para a secagem de sementes de soja, sendo associada ao período de armazenamento de 180 dias em condições não controladas.Termos para indexação: Glycine max L., germinação, vigor de sementes, pós-colheita.
