Resumo: | Dictyosperma album, commonly known as Princess Palm, due to its graceful appearance and its ability to withstand strong hurricane force winds is largely used in landscaping areas. The aim of this work was to describe the diaspores (seeds with the stuck endocarp) morphology and the stages of the D. album germination process. Therefore we concluded that the species germination is of the tubular remote type and begins with the opening of a circular operculum in the fruit endocarp, through which emerges a bulbous and hollow structure, named cotyledonal petiole or embryophore. With the embryo growth, the endosperm is being gradually consumed. The embryo grows approximately up to 10 cm, when the dilation begins in its extremity. Starting from this extensive area, it begins the growth of the primary root and the opening of a longitudinal rift, through which emerges the aerial part that is composed by two sheaths that cover the first juvenile leaf. In this phase, the emergence of secondary roots is observed. The first leaves are simple and lance-shaped. |
