Evaluación morfológica de polen en especies vegetales de Bosque Seco al sur del Ecuador

Abstract

Palynological studies are so important since these make possible the morphological makeup of the pollen grain structure, becoming into a tool that allows the identification of the plant in taxonomic and phylogenetic studies. This research was made with the purpose of describing the pollen morphology and to evaluate if there are any morphological changes within its kind of family. As result, we have the description of 46 vegetable species, 45 genres that belong to 22 families, the most particular characters are: type (Monad), symmetry (radiosymmetric) and shape of exine (psilada). The only specie that has an octáde type is the Acacia riparia. The vast majority of species have a tricolporate apertural system.
