Abstract
the five scarification methods, while for the control was 0 mday. Pre-sowing treatments included in the soaking method with water at environmental temperature and cover cut, reflected the best represented in the groups of high vigor, with 69.2 and 53.8 % from the total of storage times assessed. The index of efficiency allowed estimating that seeds evaluated at 4 mday propitiate the best
growth and development of the seedlings, without disregarding the influence of the evaluations at 2 and 3 mday on seed vigor in 50 % of the pre-sowing methods, even the control.
