Abstract

The accelerated aging test is efficient for evaluating the seed vigor of many  species, but there are few studies on forest tree species. The aim of this study was to determine the adequate exposure time of Piptadenia moniliformis Benth. seeds to the accelerated aging test in order to evaluate the vigor of seeds classified by color and size. Ten sub-lots were obtained by separating the seeds into two tegument colors (light and dark) and five size classes (11, 12, 13, 14, and 15), using round wire sieves. Before the  accelerated aging (AA) test, the seeds were treated with concentrated sulfuric acid for 20 minutes to overcome dormancy. Next, the sub-lot seeds underwent different aging times (0, 24, 48, 72, 96 and 120 hours) at 45 ºC. The  AA test, conducted at 45 ºC for 72 hours, is adequate to evaluate the quality of P. moniliformis seeds, in terms of color and size.
