The objective of present study
was determine the changes in seed developing and maturation
on germination, seedling vigor, volumetric weight and weight
of 1000 seeds. The experimental study was carried out at
Celaya, Guanajuato, Mexico during 2001. The variety used in
this study was sown at a rate of two seeds per hill in two
replications of two rows of five meters long and spaced 0.75
meters. Sampling was started 30 days after female flower
appearance then taking eight ears per treatment that were
manually shelled. Average values for germination and
seedling vigor showed the same behavior as indicatiors of
seed ripening. Volumetric weight was increased to 71 kg/ha
at 130 days after planting. No significant effect was found on
seed physiological quality due to 1000 seeds weight. The
greatest seed germination percentage and seedling vigor was
found when seed humidity was reduced from 40 to 20 %.
Samples taken 106 and 121 days after sowing were poor
indicators of seed quality. Also the greatest vigor and seed
germination was found in the basal part of the ears. These
results show that physiologic maturity is not the best
indicator for maximum seed quality but dry matter
accumulation.
