VARGAS LOPEZ, José Homero. The experiential method: its application in accelerated aging on seed germination. Universidad y Sociedad [online]. 2023, vol.15, n.2, pp. 326-335.  Epub Apr 30, 2023. ISSN 2218-3620.

In the application of the experiential method, the functions and roles played by the agents and social agencies related to the experience are of great value, in addition to their contributions to group and individual enrichment. The objective of the present work consisted of evaluating, through experiential learning, the effect of different periods of accelerated aging on the viability of seeds of Valeriana officinalis L. The study was carried out at the "César Gómez Campo" Germplasm Bank, Department of Biotechnology and Plant Biology of the Polytechnic university of Madrid, España, between July and September 2017. Six treatments were evaluated for germination, each treatment with four replicates of 25 seeds (control: without aging and addition of gibberellin acid (2.6 mM); and five periods of accelerated aging (AA) 2, 4, 6, 8, 10 days and addition of gibberellic acid (2.6 mM) for 24 h at 25 oC out of light). The variables evaluated were: germination (%) and days evaluated. The results were analyzed under a single factor ANOVA statistical analysis. The best germination was obtained with the control treatment with gibberellic acid (16%) and distilled water (12%) in a period of 47 days; higher than the values presented by the other treatments with aging that had a percentage of 0.6% and 0.4% of germinated seeds, respectively. You could determine that the V. officinalis seeds do not tolerate accelerated aging and lose their viability.
