Conteúdo: | Enterolobium contortisiliquum (Vell.) Morong. (Leguminosae-Mimosoideae) is an arboreal species of the Cerrado vegetation. The minimum germination temperatura lies between 10.9 and 11.9oC, and the maximum germination temperature is located between 40.9 and 42.4oC. The germinabilities are statistically not different from 100% between 18.2 and 38.8oC. The germination rate becomes higher as the incubation temperature increases. The plots of relative frequency of germination are predominantly platykurtic at lower temperatures and leptokurtic at higher ones. The action of temperature as a regulating factor in the germinative process is discussed, as well as the revelance of certain seed morphology and germination characteristics for the establishment of a seed bank.
