“…Similar results could observed in seeds of lettuce (Barbosa et al, 2011) and parsley (Tunes et al, 2013). Studies have shown that this effect is probably due to the high water content reached by the seeds after the aging period (Tunes et al, 2011).…”

The use of vigor tests for assessing seed lot quality is an important tool for production and commercialization. However, research on evaluating the quality of amaranth seeds is still scarce. The objective of this work was to evaluate procedures for conducting the accelerated aging test, aiming at the identification of different levels of vigour among lots of amaranth (Amaranthus cruentus L.) seeds cultivar BRS Alegria. Five seed lots were used and submitted to tests of germination, first count of germination, seedling emergence and accelerated aging, using the aging periods of 24, 48 and 72 hours and adopting the traditional methodology with water and the use of saturated (40g NaCl in 100mL of water) and unsaturated (11g NaCl in 100mL of water) sodium chloride (NaCl) solution. The accelerated aging test at 41ºC and periods of 24, 48 and 72 hours of conditioning saturated NaCl solution allowed the stratification of the lots at vigour levels, similar to the results obtained by the seedling emergence test and the first count of germination. The accelerated aging test, using saturated saline solution (40g NaCl in 100mL of water) for 24 hours at 41°C, is therefore suitable for evaluating the physiological potential of amaranth seeds.

“…The results showed that the use of unsaturated and saturated solution of NaCl provided a lower absorption of water by the seeds. Similar results founded in radish seeds (Ávila et al, 2006); in kale, broccoli and cabbage seeds (Costa et al, 2008); in urucum seeds (Torres & Bezerra, 2009) and in parsley seeds (Tunes et al, 2013).…”

“…Seedling emergence of carrot variety "Brasilia" was around 80 % from 28 DAA to 63 DAA (Miranda et al, 2017), but in our results carrot varieties show values around 89 %, except "Jolana" with 77 %. In the case of parsley variety "Lisa Comum", where four seed lots were used, values of seedling emergence ranged from 48 -81 % (Tunes et al, 2013). The range of seedling emergence of our 3 parsley varieties was not as wide and ranged from 65 -78 % (Fig.…”

In this study, we assessed the content of chlorophyllaandb, β-carotene and lutein in seeds of carrot, celery, dill, parsley and parsnip commercial varieties by spectrophotometric method. It was determined that the content of chlorophyllawas higher than chlorophyllband both differed significantly between plant species and varieties. The highest amounts of chlorophylla, chlorophyllb, β-carotene and lutein were detected in parsley “Olomoucka dlouha”. The lowest amounts of chlorophylla, chlorophyllb, β-carotene and no lutein were detected in celery “Nuget”, however, very low amount of lutein was detected in the parsley cultivars “Atika” and “Orbis”. The content of β-carotene was higher than that of lutein in most varieties. The individual pigment contents were compared to seed quality parameters such as standard laboratory germination and seedling emergence. Negative correlation between energy of germination and pigments and positive correlation between seedling emergence and pigments in the parsnip and parsley varieties was observed. Determination the content of pigments and correlations observed the possibility to use spectrophotometry to evaluate the pigments present in the seeds as an indicator of seed quality.

“…Among the proposed methods, the accelerated aging test is promising and shows practical interest (Lima et al, 2006), besides being recognized as one of the most used to assess the physiological potential of seeds of several species, such as lettuce and eggplant (Santos et al, 2011;Lopes et al, 2013), providing highly consistent information (Tunes et al, 2013). The test is based on the artificial acceleration of seed deterioration through the exposure to high temperature and relative humidity conditions, which are considered as the environmental factors that most affect the intensity and speed of deterioration (Marcos-Filho, 2015b).…”

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.
