摘要: A study to elucidate the productivity contribution of benthic macrophytes in a fertile estuary was undertaken. Methods for utilizing C\U14\N uptake as monitor plants are described. Both phytoplankton and macrophyte determinations were made at various distances from small sewage outfall, effect nutrients on seaweeds observed. It also observed that flora better indicator nutrient enrichment, because there uniform gradient stimulation away outfall. The showed erratic values outfall due mixing out fertilized zone. is proposed model such Baule-Mitscherlich relationship can be used predict photosynthetic response algae combination nutrients. This will allow concept multiple limiting nature.
