Abstract

The efficiency of energy storage in photosynthesis is a sensitive indicator of different kinds of stress to which plants are exposed. In this study, phytoplankton samples were obtained from irrigation and drinking-water reservoirs differing in trophic status, and their photosynthetic efficiency was examined using the photoacoustic method. We examined changes in photosynthetic energy storage efficiency over time in natural samples collected from the field, and following their enrichment with nitrogen and phosphorus. It was evident that as phytoplankton grew, both nutrients became depleted, nitrogen earlier than phosphorus.
