Resumen
PLASENCIA FRAGA, José Miguel. INFLUENCIA DE LA PROFUNDIDAD SOBRE LA DISTRIBUCIÓN ESPACIAL Y TEMPORAL DE LABIOMASA EN POBLACIONES DE POTAMOGETON ILLINOENSIS MORONG EN ACUATORIOS CUBANOS. Polibotánica [online]. 2006, n.22, pp.79-88. ISSN 1405-2768.
An assessment was made of the influence of depth on spatial and temporal biomass in Potamogeton illinoensis in five Cuban reservoirs. Shoots of representative populations were cut at bottom level and divided into equal segments from the bottom to the surface. Leaves and shoots were segregated and dried at 105°C in order to obtain the dry weight. There was a tendency for biomass increase as depth increased. Biomass of leaves and stems showed a tendency to increase from the bottom to the surface, the highest values for leaves corresponding to the segments closer to the surface.
