“…In general, the effect of lots showed similar vigor values between the levels of period effects, with the exception of 24 h, where lot 6 was categorized differently from the others tests performed. The SatSAA provided more consistent results due to lower water content absorbed by the seed and the lack of apparent growth of microorganisms, which concurs with the findings in the literature (Vieira et al, 2013;Almeida et al, 2014).…”

“…Despite being conducted along with the germination test, which basically provides that the seeds express their maximum germination (Brasil, 2009), the lots were divided into seven physiological quality categories, being the lot 10 classified as superior than the others. Similar results were observed in lots of Coriandrum sativum and Raphanus sativus seeds, demonstrating the sensitivity of the FGC to differentiate the physiological quality between lots (Vieira et al, 2013).…”

-The objective of this study was to evaluate the accelerated aging test, with and without NaCl solution, predicting the physiological health and quality of birdsfoot trefoil (Lotus corniculatus L.) seed. The experimental design was completely randomized. Ten seed lots were submitted to three conditioning periods (24, 48 and 72 h at 41 ºC). The physiological characterization of the lots was the determination of water content (before and after accelerated aging), germination, first germination count, germination speed index, seedling emergence and seed health test. The data were submitted to variance analyze and the averages were compared by the Scott-Knott test, at 5% probability. The accelerated aging methodologies with saline solution and saturated NaCl solution, conditioned for 48 h, were correlated with seedling emergence test (0.52 and 0.69, respectively), allowing the prediction of physiological quality of birdsfoot trefoil seeds. The use of saturated solution for 48 h decreases incidence of fungi. The traditional method is not suitable because it provides water content variation between samples above the tolerable.Index terms: fungi, germination, saline solution, vigor.Parâmetros do envelhecimento acelerado na predição da qualidade fisiológica e sanitária de sementes de cornichão (Lotus corniculatus L.) RESUMO -O objetivo deste trabalho foi avaliar o teste de envelhecimento acelerado, com e sem solução de NaCl, na predição da qualidade fisiológica e sanitária de sementes de cornichão (Lotus corniculatus L.). O delineamento experimental foi o inteiramente casualizado, foram utilizados dez lotes de sementes submetidos a três períodos de condicionamento (24, 48 e 72 h, a 41 ºC). A caracterização fisiológica dos lotes consistiu na determinação do teor de água (antes e depois do envelhecimento acelerado), germinação, primeira contagem de germinação, índice de velocidade de germinação, emergência de plântulas e teste de sanidade de sementes. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Scott-Knott, a 5% de probabilidade. As metodologias de envelhecimento acelerado com solução salina e solução saturada de NaCl, condicionadas por 48 h, correlacionaram-se com o teste de emergência de plântulas (0,52 e 0,69, respectivamente), permitindo a predição da qualidade fisiológica de sementes de cornichão. A utilização de solução saturada durante 48 h diminui a incidência de fungos. O método tradicional não é recomendado por proporcionar variação do teor de água entre as amostras, superior ao tolerável.Termos para indexação: fungo, germinação, solução salina, vigor.

“…The accelerated aging test was developed and further refined to evaluate the seed vigor of several species such as cowpea (DUTRA & TEÓFILO, 2007), wheat (PEDROSO et al, 2010), lettuce (BARBOSA et al, 2011), okra (TORRES et al, 2014, crambe (LIMA et al, 2015), arugula (VIEIRA et al, 2015), and coriander (PEREIRA et al, 2015).…”

Accelerated aging as vigor test for sunn hemp seeds

2017

This study aimed to determine the most appropriate method to assess the sunn hemp ( Crotalaria juncea L.) seed vigor in the accelerated aging test. Five seed lots from harvest 2007/2008 were evaluated for germination, vigor and seedling emergence in the field. Accelerated aging test was performed at 41°C during 48, 72 and 96 hours, with and without sodium chloride saturated solution. Then, the promising procedure was also performed for 2008/2009 and 2009/2010 harvests. In the traditional accelerated aging test, the no-uniform water acquisition by the seeds adversely affected results. Accelerated aging test with sodium chloride saturated solution is the most appropriate method to evaluate the physiological potential of sunn hemp seeds, and the combination of 41°C and 96 hours is efficient for separating of seed lots in different vigor levels.

“…However, for lettuce seed lots, this test proved to be the most sensitive to the stratification of the lots (Nascimento & Pereira, 2007). The accelerated aging test was more sensitive than germination to detect differences in seed vigor in rocket seeds (Vieira et al, 2015). Importantly, each test has its peculiarity in the differentiation of physiological quality of seeds, so it is necessary to use several tests to be able to detect small differences in vigor between lots.…”

Cucumber is a very important crop produced and consumed in Brazil. Its seeds have high commercial value and deserve special attention due to their physiological and sanitary quality. Therefore, studies aiming at determining seed vigor should be intensified because the germination test used for assessing the quality of seeds often shows no correlation with field emergence. The present study was carried out to evaluate the physiological and sanitary qualities of cucumber seed lots. The study was conducted at the Laboratory of Seed Analysis and at the greenhouse of the Department of Plant Science, at the Universidade Federal de Pelotas (UFPel). Four lots of cucumber seeds, cultivar 'Aoidai', were tested for the following features: germination, first count germination, accelerated aging, electrical conductivity, cold test, sanitary condition, and seedling emergence. The experimental design was completely randomized with four replications. Means were compared by Tukey test at 5% probability. It was concluded that the accelerated aging test showed efficiency to evaluate the physiological quality of cucumber seeds. However, the cold test, with evaluations at 3 and 5 days, proved to be the most efficient for distinguishing differences in vigor levels between the seed lots.The incidence of fungi associated with seeds of cucumber do not affect the physiological quality of the lots.
