Characteristics of the development of photosynthesis in some submerged phanerogams as a function of the intensity of light


, : Characteristics of the development of photosynthesis in some submerged phanerogams as a function of the intensity of light. Studii si Cercetari de Biologie Seria Biologie Vegetala 36(1): 42-46

In this study we have investigated the influence of light intensity upon photosynthesis in case of six species of the most widespread submersed phanerogams in the aquatic ecosystems: Ceratophyllum demersum, Myriophyllum spicatum, Elodea canadensis, Vallisneria spiralis, Potamogeton crispus and Potamogeton pectinatus. The results obtained showed that with these phanerogams, depending on the light intensity, photosynthesis has a display similar to that of terrestrial plants growing in places with low light intensity. Among the studied species, there have been registered differences as concerns the photosynthesis values and the illumination intensity at which this process is highly developed.

The central mechanism that mediates litorin-induced satiety is poorly understood, and has not been studied in a non-mammalian species. Therefore, the aim of this study was to determine if litorin-induced satiety in an alternative vertebrate model,...
