          Abstract

          Se evaluaron algunos parámetros fisiológicos de Aloe vera en dos parcelas, una alejada del mar (parcela A) y otra cercana al mar (parcela B), próximas a la localidad de Guayacán, Península de Araya, estado Sucre, Venezuela, durante las estaciones seca y lluviosa. Se determinó el volumen y contenido relativo de agua (CRA) foliar, el contenido de proteínas y prolina en extractos acuosos clorenquimáticos y la aloína foliar exudada. El volumen foliar fue menor en las plantas cosechadas de la parcela B y durante la estación seca; mientras que el CRA solo fue menor en la estación seca. El clorénquima de las plantas cosechadas en sequía tuvo menor contenido de proteínas y prolina. El contenido de proteínas también fue menor en la parcela B. Las hojas de sábila de la parcela alejada del mar, durante la estación seca, presentaron los máximos valores de aloína. Los resultados sugieren cultivar sábila en zonas costeras no muy cercanas al mar y con un suministro apropiado de agua para obtener mayor volumen y CRA foliar. Si lo que se quiere es alcanzar mayor producción de aloína, entonces es aconsejable suministrar poca agua al sitio de cultivo.

          Some physiologic parameters of Aloe vera were evaluated in two plots, plot A far from the sea and plot B near the sea, both situated close to Guayacán, Araya Península, Venezuela during dry and wet seasons. Leaf volume and relative water content (RWC), protein and proline contents in aqueous chlorenchymatic extracts and foliar aloin exudates were determined. Leaf volume was smaller in plot B in harvested leaves during the dry season; whereas RWC was only smaller in the dry season. Chlorenchyma protein and proline contents were smaller in drought harvested plants. Protein content was also smaller in plot B. The aloin maximum levels were found in A. vera leaves of plot A and in the dry season. The results suggest that A. vera could be cultivated in coastal zones but not so near the sea and with adequate water supply in order to obtain larger foliar volume and RWC. If instead, a larger production of aloin is desired, it is advisable to supply little water to the plants in the cultivated area.
