Twenty-five ecotypes from different natural stations were gathered in the collection of Elizówka, Poland, in 1989-1991. Content of calcium, magnesium, total protein, phosphorus and potassium was measured in the dry mass of plants collected during full flowering. On this ground, differences in the potassium content (variation coefficient 48.3%) were observed within the ecotypes. The smallest deviations were found in the total protein content (22.2 %) The ecotypes were significantly differentiated in terms of the investigated components content. It was observed that the objects from weakly fertile habitats were usually poor in total protein and macroelements. Besides, an important correlation between content of nutrients in the plant mass was statistically confirmed.
