Germination of Dyckia encholirioides var encholirioides (Bromeliaceae, Pitcairnioideae)

Abstract

Dyckia encholirioides is a bromeliad considered vulnerable, because it is found in restricted areas and in interrupted agglomerates, dispersed through the center-south of Brazil, being considered endemic of those regions. Due to this fact and because of the ecological importance of this species, this work describe a methodology for Dyckia encholirioides seeds germination. The data analysis reveals that the cold delays the germinative potential of this species, without decreasing, the germinative index. This species have no germinative limitation when germinated in vitro, unlike what happen in nature, where finds other barriers, probably of physical nature that decrease. the germination.
