El tamaño de las semillas de ismia glaziovii Ruhl. (Guttiferae) y su relación con la velocidad de germinación y tamaño de la plántula

Abstract

In the present work I analyzed the variability of the seeds size of ismia glaziovii Ruhl. and its possible effect on germination speed and its seedling size. The results show that the size of the seeds does not vary significantly between trees from which they came; but the variation as large as seed between the fruits of each tree is significant. Also, the size of the seed does not influence the speed of germination nor the seedling size. We suggested that variability in size is not sufficient as indicator of differences in the amount of stored resource. This study will allow contributing to the knowledge of some aspects of the dynamics of seeds and the regeneration of this species.
