“…When seeds were submitted to the conventional accelerated aging method, the moisture content increase was proportional to the exposure time. This result corroborates with the studies of Barbosa et al (2011) and Torres et al (2014) on lettuce and okra, in which they verified a higher absorption speed and a greater quantity of water absorbed in seeds aged in conventional solution.…”

“…The physiological parameter of seed quality is determined by the germination test, which is conducted under favorable conditions that allow seeds from the lots to express their maximum germination capacity (Pereira et al, 2011). However, the results can be overestimated and may not express the true quality of the lot.…”

Methodological adjustment of the accelerated aging test to evaluate the vigor of chia seeds

-Chia cultivation is expanding in Brazil, but there is still no standardized test to evaluate the quality of the seeds. Therefore, vigor tests that expose seeds to stress conditions must be standardized. This study aimed to establish the methodology for the accelerated aging test in chia seeds. Six chia seed lots with similar germination behavior were used. They were submitted to germination, first germination count, seedling emergence, emergence speed index and accelerated aging tests. Aging periods of 24, 48, and 72 hours were used in the conventional methodology, and also with the use of unsaturated and saturated sodium chloride (NaCl) solutions. The results obtained from the accelerated aging tests revealed tendencies for lot separation similar to the classification of chia seed lots in relation to the physiological potential obtained in the preliminary quality tests. The accelerated aging test can be used to evaluate the physiological potential of chia seeds by using water or unsaturated saline solution. In the conventional test (water), the seeds should be exposed for 24 hours. When using unsaturated saline solution, the exposure time must be of 48 hours.

“…However, among the aging periods, only the period of 96 hours was able to classify seed lots in accordance with the vigor level, which identified the lowest vigor of lot 3 in addition to confirmation of low physiological potential of lot 5. The SSAA for 96 hours was also efficient to detect differences among okra seed lots (TORRES et al, 2014) and wheat seed lots (PEDROSO et al, 2010). The SSAA during 48 and 72h were not considered suitable for sunn hemp seeds (Table 2), whereas 48 and 72h were the SSAA period recommended for other legume such as cowpea (DUTRA & TEÓFILO, 2007) and coriander (PEREIRA et al, 2015) seeds, respectively.…”

Accelerated aging as vigor test for sunn hemp seeds

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.

“…The germination and vigor tests are essential components of the quality control process of seed companies (Torres et al, 2014). Among the vigor tests, the seedling length test has potential to provide additional information to those obtained in the germination test and enable to estimate the potential for seedling emergence in the field (Guedes et al, 2009) Due to the above, the objective on this study was to evaluate the germination and vigor of Macrotyloma axillare cv Java (archer) seeds under different methods of overcoming dormancy.…”
