All tested metals (Cd, Cr and Pb) treatment reduced the number of nuclei in 4C DNA class and induced appearance of nuclei with DNA amount below 2C, that was expressed in diminished DNA content. The level of NYS proteins in cells underwent also reduction. In lead presence protein content diminished in nucleus. On the other hand, increased amount of nuclear, nucleolar and cytoplasmic proteins was observed in material treated with cadmium while only of nucleolar protein content in chromium presence. In root cells treated with tested metals protein content in nucleus was related with ploidy level, disturbances in this relation appeared in nucleolus and mostly in cytoplasm.
