| Abstract:
Effects of CuSO4.5H2O, copper salicylate tetrahydrate and seven copper(II) chelates (diaqua-(N-pyruvidene-  -alaninato)copper(II) monohydrate, potassium (N-salicylidene-L-glutamate-aqua)cuprate(II) dihydrate as well as N-pyruvidenegly-cinatocopper(II) complexes with additional molecular S-donor (urea and ethylenethiourea), N-donor (pyridine and aniline) and O-donor (H2O) ligands) on dry mass and Cu accumulation in Matricaria recutita plant organs (‘Goral’) as well as on the concentration of assimilation pigments (chlorophylls and carotenoids) were investigated.
The applied concentration of the studied compounds was 24 µmol dm-3. In general, Cu was allocated predominantly in chamomile roots.
Accumulated Cu amount in roots and shoots depended on the structure of applied Cu(II) compound.
Bioaccumulation and translocation factors (TF) were also evaluated.
It was found that application of copper in the form of chelate led to more effective Cu translocation into the shoots in comparison with CuSO4 5H2O treatment.
The highest TF was obtained for Cu(pyrgly)(py)(H2O)2, the lowest one for CuSO4. The TF values of the studied chelates as well as [Cu(sal)2.(H2O)2].2H2O were higher than TF determined for CuSO4.5H2O. Application of CuSO4.5H2O, K+[Cu(sal-L-glu) (H2O)].2 H2O and [Cu(pyr--ala)(H2O)2]H2O resulted in significant reduction of the concentration of assimilation pigments in comparison with the control variant.
