Resumo
This research had as objective to evaluate the germination
and emergence speed index (ESI) of pequi (C. brasiliense Camb.)
from sexual propagation material (putamens and seeds) from
two sites, Porangatu and Faina, Goiás State, Brazil. Twelve
treatments were evaluated (2x6 factorial), the two procedences
being combined with six sowing methods: putamens (inner
mesocarp and endocarp) immersed in water; putamen without
pulp (inner mesocarp) immersed in water; seeds (almonds)
immersed in water; putamens immersed in giberelic acid solution
10%; putamens without pulp immersed in giberelic acid solution;
seeds (almonds) immersed in giberelic acid solution. The
experimental design was randomized complete blocks with four
replications. The experiment took place in a screen-house at
50% shading. The observations were taken every 48 hours for 77
days from seed planting. It was not observed significant variation
(p>0.05) between fruit origin in germination and ESI. Putamens
with or without pulp and treated with giberelic acid presented
satisfactory germination indexes, above 30%, and superior
(p<0.05) to those immersed in water. For almonds, the treatments
with giberelic acid and water immersion did not differ (p>0.05)
in this characteristic. Besides, significant (p>0.05) effect of the
treatments was not detected on plantules ESI.
