Photosynthetic pigment proportion in aquatic higher plants according to the level of anthropogenic load
Journal Title: Екологічні науки - Year 2018, Vol 22, Issue
Abstract
It has been researched proportion changes of plastidial pigments in higher aquatic plants biomass under the different level of anthropogenic load for Rivne rivers water ecosystem (recreational, urbanized, agrarian, and technogenically transformed territories). According to chlorophyll-a proportion plants have been distributed in such way as plants with pads (Lemna minor L.) > submerged ones (Potamogeton pectinatus L., Potamogeton perfoliatus L., Ceratophyllum demersum L. and Elodea canadensis Mich.) > aeroaquatic ones (Sagittaria saggitifolia L. and Tуpha angustifolia L.). According to chlorophyll-b proportion plants have been distributed in such way as submerged ones (Potamogeton pectinatus L., Potamogeton perfoliatus L., Ceratophyllum demersum L. and Elodea canadensis Mich.) > plants with pads (Lemna minor L.) > aero-aquatic ones (Sagittaria saggitifolia L. та Tуpha angustifolia L.). In researched species chlorophylls total (a+b) depends on different factors and has been changed from 7 till 41 microgram per milligram of dry mass. Chlorophylls average value (a+b) has been presented in 17–22 microgram per milligram of dry mass. The author gives a rationale for prospects in using of higher aquatic plants plastidial pigments as the bioindicators to evaluate river ecological state under the conditions of anthropogenic load.
