| Popis | Effects of zinc (12-180 mu M) alone and in mixtures with 12 mu M Cd on metal accumulation, dry masses of roots and shoots, root respiration rate, variable to maximum fluorescence ratio (F-V/F-M), and content of photosynthetic pigments were studied in hydroponically cultivated chamomile (Matricaria recutita) plants. The content of Zn in roots and shoots increased with the increasing external Zn concentration and its accumulation in the roots was higher than that in the shoots. While at lower Zn concentrations (12 and 60 mu M) the presence of 12 mu M Cd decreased Zn accumulation in the roots, treatment with 120 and 180 mu M Zn together with 12 mu M Cd caused enhancement of Zn content in the root. Presence of Zn (12-120 mu M) decreased Cd accumulation in roots. On the other hand, Cd content in the shoots of plants treated with Zn + Cd exceeded that in the plants treated only with 12 mu M Cd. Only higher Zn concentrations (120 and 180 mu M) and Zn + Cd mixtures negatively influenced dry mass, chlorophyll (Chl) and carotenoid content, F-V/F-M and root respiration rate. Chl b was reduced to a higher extent than Chl a. |
