“…In this sense, seed vigor tests and the very concept of vigorous seeds are used in seed production programs as an important strategy for controlling quality, since they help to guarantee an adequate positioning of the plant population in the field (Silva et al, 2017).…”

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.

“…Nevertheless, in spite of this differentiation, for these periods of accelerated aging of 72 and 96 hours, the decline in germination was drastic, as also observed by Oliveira et al (2014) in physic nut and by Silva et al (2017) in rattlepod (Crotalaria).…”

Accelerated aging for evaluation of vigor in Brachiaria brizantha ‘Xaraés’ seeds

et al. 2020

The aim of this study was to adjust the accelerated aging test to evaluate the physiological potential of seed lots of Brachiaria brizantha ‘Xaraés’, represented by four lots. Seeds were tested by traditional accelerated aging and with saturated NaCl solution in five aging periods: 0, 24, 48, 72 and 96 hours. The profile of the lots was determined by the following measures: moisture content, germination test, first germination count, germination speed index, initial stand, emergence, and emergence speed index. The accelerated aging test makes it possible to separate the lots by the method of saturated NaCl solution for 24 hours and it is appropriate for evaluation of seed physiological potential.

“…Variations in root growth in the different substrates were attributed to their particle size conditions, which may or may not enable rooting, depending on the aeration conditions. Number of leaves, fresh mass, and dry mass variables are suitable for evaluating vigor based on seedling development, and are used to complement the information obtained from germination test (BARBOSA et al, 2012;SILVA et al, 2017). A higher number of leaves is related to more vigorous seedlings because of greater germination potential; and consequently, higher speed of leaf formation.…”

Desert rose (Adenium obesum) is a succulent plant that is native to the Arabian Peninsula. It has great commercial value with exuberant structure and flowering. It can be propagated by seeds to ensure maximum development of the caudex. Despite its high economic value, studies on its propagation are still required. The aim of this study was to evaluate seed germination performance and seedling development of desert rose seedlings in different substrates. Treatments comprised five different substrate compositions: S1 (Soil), S2 (Sand), S3 (Carolina Soil commercial substrate), S4 (Sand + Carolina Soil), and S5 (Soil+ Carolina Soil). The following were evaluated using uni- and multi-variate approaches: germination, first count, germination speed index, caudex diameter, number of leaves, seedling length, root length, shoot length, and fresh mass and dry mass. Sand is the ideal substrate for the germination of A. obesum seeds, while for forming seedlings, mixtures of the Carolina Soil commercial substrate with sand or soil should be used.
