Abstract
Nowadays much attention is paid to the quality of wetlands and waters. Environmental data on pollutants are not sufficient to understand the direct effects of negative compounds on aquatic flora. There is also the question of human impact on the environment. Land use is facing a major pollution load, in particular due to the use of fertilizers in agriculture, which falls in inland waters. Nitrogen (N) is the main mineral nutrient needed for plants and it plays an essential role in the plant life cycle. The nutrient evaluation could help to understand the affection level for environment. Lythrum salicaria is riparian plant species, naturally occurring the riverbanks in Europe but is invasive in the United States of Amerika and Canada. This plant used for medical purposes, has many secondary metabolites and is important as indicator of soil salinity. There are genetical evaluations of this plant, but there is a lack of information about ecophysiological parameters, especially in the Baltic countries. Our task was to evaluate leaf N concentration differences and compared it among populations of L. salicaria growing in different sites of Lithuanian rivers. Our study involved 29 populations of selected plant species, sampled on the Nemunas river and seafront catchments. Three independent batches of healthy leaves were dried, turned to the powder and analyzed by Kjeldahl method. Nitrogen concentrations were expressed as percentage of dry mass (d.m.).[...]
