Estudio morfológico de los órganos vegetativos de puya santosii, una especie endémica de la región altoandina de Colombia

Abstract

This study has as principal aim realize a morphologic description of the vegetative organs of the Puya santosii, concerning a descriptive investigation. Puya santosii is an endemic species of the Altoandina Region of Colombia that belongs to the Family Bromeliaceae, where the majority of plants of the kind Puya live in moors. The collection of the vegetable material was done in the Ecological Park Matarredonda located in the Municipality of Choachí - Cundinamarca. From the collected samples, in the laboratory a description was realized organographic, detailed of the plant and, besides the identification of the internal tissues that are stem, root, leaf; for such an end, histological protocols were used on the basis of the proposed by Sandoval (2005). On the other hand, it is investigation was born of the need for knowing the morphology of Puya santossi, since they find little works that realize descriptions of the internal and external anatomy of the plant. On the other hand, the condition of conservation and the category of threat of this species, according to UICN, is classified as almost threatened (NT) is to say, a species close to be categorized like vulnerably (Betancour & García, 2006) therefore, this work is a contribution to the knowledge and conservation of the flora of the country especially in ecosystems of moor
