, situated preferably at Stage I of the viability loss
curve, since when Stage II is attained, even the
germination test (conducted under favorable conditions)
is capable of detecting differences in physiological
potential in the evaluated samples. This author considers
that the position of each lot within Stage I determines its
vigor level. In this study, all lots had germinations ranging
between 88 and 98%, and are therefore situated at Stage
I of the seed viability loss curve, characterized for its
relatively long duration and for presenting few dead
seeds.
