INFLUENCE OF HERBICIDES AND SOME HEAVY METALS ON GROWTH OF MATRICARIA CHAMOMILLA L. AND THE BIOSYNTHESIS OF THE ESSENTIAL OILS |
| Author: | H. Schilcher |
| Abstract:
The residues of the herbicides atrazine, prometon, prometryn, linuron and 2.4-dichlorphenoxyacetic acid and of the heavy metals lead, cadmium and mercury found in the flowers of Matricaria chamomilla depended on both the amount and period of application. The growth of the plants and the composition of the essential oils were strongly influenced by the more substantial atrazin treatments. Application of linuron after germination damaged the cultivated plants more than the weeds. After 2.4-D treatments no significant differences in the composition of the essential oils in comparsion with untreated plants could be observed. In most commercial samples of camomile flowers lead, cadmium and mercury was found. At a threshold level of 3.8 ppm lead there is a significant inhibition of potassium uptake. The experiments were carried out with 42potassium and 32phosphate. | |
