“…Therefore, as recommended by Marcos-Filho (1999a), the ageing test evaluations could be carried out on the date of the first germination count. The severe seed damage caused by ageing at 45 °C (Table 4) was also reported for common beans (Bertolin, 2011), and cauliflower seeds (Kikuti and MarcosFilho, 2008) where germination was greatly reduced after the 48 hour period and no germination was observed after the 72 hour period. The high germination rates observed under SSAA (Table 5) may result from the salt (NaCl) used in this method that reduces relative air humidity inside the plastic germination box to approximately 76%.…”

Adequate seed vigour tests are fundamental in evaluating vigour level and consequent performance of seed lots in storage and in the field conditions. The accelerated ageing is one of the most important of these tests. To establish the best accelerated ageing procedure for evaluating the vigour of crambe seeds, we compared results from the traditional method (ageing periods of 24, 48, and 72 hours at temperatures of 41 and 45 °C) and the saturated salt accelerated ageing (SSAA) (NaCl) method. In addition to accelerated ageing, germination in a sand substrate, seedling emergence in laboratory, and seed moisture content before and after seed ageing were determined. Our first count was highly sensitive in detecting seed vigour level. Both the traditional and SSAA methods can be used to efficiently classify the vigour of crambe seed lots and could be promising techniques for crambe seed quality control programs. To evaluate vigour of crambe seed lots, the traditional accelerated ageing test should be executed for 48 hours at 41 °C and the SSAA method, for 24 hours at 41 or 45 °C. Seedling assessment should be carried out on the fourth day for both methodologies.

“…The results for accession characterization according to seed viability, using the germination test ( Bertolin et al (2011) analyzed the effects of temperatures and exposure time of six bean accessions to accelerated aging and found genetic diversity as a response to the vigor test according to aging, at different temperatures and exposure times. According to Krzyzanowski et al (1982), the accelerated aging test is effective in assessing bean seed vigor, making it possible to observe diversity through this characteristic.…”

Agrobiodiversity is essential for a sustainable food production, and the knowledge of the potential characteristics of landrace seeds may prompt farmers to adopt the habit of seed conservation for this species. This study aimed at categorizing landrace and commercial common bean (Phaseolus vulgaris L.) accessions, according to the physiological quality (viability and vigor) of seeds produced in the field, during two growing seasons, under organic and conventional farming systems. Germination percentage, field emergence, electrical conductivity, accelerated aging, cold test and seedling length were assessed. The landrace bean accessions exhibit diversity in the physiological seed quality, in terms of their viability and vigor. No differences were observed between the farming systems, in relation to the physiological quality of the seeds produced. The categorization of landrace common bean accessions allows to identify those with superior physiological seed quality.

“…Corroborating with Bertolin et al (2011), with the application of the accelerated aging test, there was decreased germination and increased deterioration of mungbean seeds as a function of increasing exposure time within each temperature. Regarding the behavior of each lot, some materials were shown to be more resistant to the adverse conditions imposed by the test, which suggests the need for studies with different temperatures and exposure times.…”

“…When working with accelerated aging test parameters to determine the vigor of bean seeds, Bertolin et al (2011) observed that bean seeds with good quality (germination) present alterations in the accelerated aging test; the authors obtained satisfactory results when using the temperature of 43 °C for 24 h. Guiscem et al (2010), evaluating both the cold test and the accelerated aging test in the determination of asparagus bean seed vigor, observed positive results when using the temperature of 43 ºC for 48 h.…”

The use of good quality seeds is fundamental for proper establishment of a crop. In this way, for more precise determination of seed quality, vigor tests are performed in addition to the germination test. These tests enable the selection of the best lots for commercialization and planting. This study evaluates the effects of temperature and exposure times of the accelerated aging test for vigor classification of mungbean seed lots. Seeds of the mungbean cultivar Esmeralda were used, being obtained from four cultivated plots at the State University of Goiás (UEG), Ipameri Câmpus, in the 2013, 2015, 2016, and 2017 harvests. The lots were initially characterized using germination and vigor tests (first germination count, germination rate index, seedling length, and seedling fresh and dry weight). The accelerated aging test was conducted with a completely randomized experimental design, in a 2 × 4 factorial arrangement consisting of two temperatures (40 and 42 °C) and four times (24, 48, 72, and 96 hours), with four replicates of 50 seeds per lot. The lots showed significant differences in the germination test, first germination count, germination rate index, and seedling length. The accelerated aging test was efficient in classifying lots. Lot 3 obtained the best results, while lot 1 obtained the lowest ones. The combination of 42 °C temperature and 72 h of seed exposure to the accelerated aging test is the best to classify mungbean seed lots.
