This test classified the lots with the best and worst
performance, in a way similar to that verified in the
germination test, especially for the hybrid AF-682. The
seedling emergence test is an indicator for the efficiency
of tests that evaluate the physiological potential of seed
lots (Marcos Filho, 1999a). Therefore, it was observed
that this efficiency in safely discriminating lots that exhibit
low and high vigor was more evident for lots of the hybrid
AF-682, while those of the hybrid AF-646 had a relative
uniform quality, and only lot 1 was identified as having a
lower physiological potential.
