Description
  • It was found that Zn application to the soil can decrease Cd accumulation in chamomile plants1,2. This study was focused on the investigation of increasing concentration of Zn (12, 60, 120, 180 umol/dm3), 12 umol/dm3 Cd and of their combinations on growth and development of chamomile (Matricaria recutita L.) plants cultivated in hydroponics. Phytotoxic effect of simultaneously applied metals was very low confirming high tolerance of chamomixe to Cd and Zn. The application of 12 umol/dm3 Cd significantly reduced the content of photosynthetic pigments (chlorophyll a, chlorophyll b, carotenoids), but an addition of Zn did not affect significantly these photosynthetic parameters. The results also confirmed significant reduction of root respiration rate and reduction of maxima fluorescence quantum yield by higher concentration of zinc as well as by 12 umol/dm3 Cd. The content of Cd and Zn in plant organs increased with increasing metal concentration in the external solution.
