Teste de condutividade elétrica em sementes de soja armazenadas sob diferentes temperaturas

Abstract: ELECTRICAL CONDUCTIVITY TEST OF SOYBEAN SEEDS STORED UNDER DIFFERENT TEMPERATURESThere are some results showing that the electrical conductivity test can be influenced by low temperature of seed storage, such as 10 o C. This work was carried out in order to study the effect of temperature and period of storage on electrical conductivity and chemical composition of the imbibing solution of soybean seeds. For that, seed water content, germination, vigor (accelerated aging, cold test and electrical conductivity),… Show more

“…The best quality of cooled seeds, over storage, can be related to the lower temperature of the seed mass in the first 15 days of storage (Figure 2A). It has been observed that the temperature affects the leaching of solutes in soybean seeds (Vieira et al, 2008;Fessel et al, 2010). However, there is no direct relationship between the leaching of solutes and the content of fatty acids and carbohydrates in seeds (Panobianco and Vieira, 2007).…”

“…However, variation in electrical conductivity values, over the experiment, indicates that the test wasn't sensitive enough to detect a decrease in beans vigor, corroborating with Silva et al (2012), who studied beans of high vigor; with Fessel et al (2010) who tested soy seeds stored at 10 and 20 ºC, and finally with Soares et al (2010), using sorghum seeds. However, the test was effective to distinguish beans vigor in Santos et al (2005) work, and also to batches of beans studied by Cassol et al (2012), during storage for eight and three months, respectively.…”

“…High concentrations -of the above substances -can be an indicative of vigor and germination loss (MARCOS FILHO, 2005;BINOTTI et al, 2008). Among the best studied electrolytes, to try establishing a correlation with physiological quality of seeds, are calcium, magnesium and potassium, which are researched by many authors (BINOTTI et al, 2008;COSTA et al, 2008;FESSEL et al, 2010;SILVA et al, 2012).…”

“…According to Coradi et al (2011), reading the electrical conductivity of the solution containing the seeds can be used to evaluate this effect, since the conductivity value is related to the amount of ions leached into solution, which is directly associated with cell membrane integrity; poorly structured damaged cells and membranes are generally associated with seed deterioration and, therefore, the low vigor. The lowest values, corresponding to the lowest level of ions indicate high physiological vigor and show less intense disorganization of the cell membrane system (PANOBIANCO et al, 2007;FESSEL et al, 2010).…”
