Resumo
"Cagaita" is a native species of "cerrado" savannah, with
very irregular seed germination. The objective of this study was
to evaluate the effect of harvest type and seed size on the
germination rate and vigor of Cagaita seeds. The experiment was
carried out in a 2 x 3 factorial completely randomized design with
six treatments: two harvest types (from the tree and on the
ground) and three seed sizes (large, medium, small). Germination
started fourteen days after planting and ended in the 60th day.
The germination and seedling early growth were described and
illustrated by drawings. Large seeds harvest on the ground present
lower humidity, greater seedling vigor, and higher fresh matter.
There were not found significant differences for germination rate
treatments. It was concluded that Cagaita seeds should be obtained
from ripe fruits on the ground. Large seeds from those fruits
showed to be more vigorous. In seedling production and
germination tests the separation of seeds by size may be applied
for obtention of seed lots with uniform vigor.
