| Abstract:
Matricaria recutita L. belongs to the most favoured medicinal plants in Slovakia. In Eastern Slovakia some large regions are used for commercial chamomile cultivation. Cd concentrations in the soil (determined in 2M HNO3 leachate) and in chamomile anthodium (pharmaceutical important plant part) were estimated and corresponding bioaccumulation factors (BAF) related to some localities in Slovakia in which field cultivation of chamomile occurred (for the period 1999-2001) were evaluated. Bioaccumulated Cd amount in anthodium was correlated with the hydrothermic coefficient (HC), an integrated index of hydrothermic parameters. It was found that increase of HC value resulted in more efficient Cd bioaccumulation in anthodium. The study was completed with determination of Cd content in individual plant organs of chamomile plants cultivated in pot experiments. The Cd content in plant organs increased proportionally with the increasing Cd content in the substrate. It was found that Cd bioaccumulation in the shoots and roots was higher than that in anthodia. | |
