Other claims from this paper (7)
- Intervention effect Copper sulphate at all tested concentrations decreased seed germination of T. aestivum relative to the control by 23–58%, a lethal effect.
- Intervention effect Both toxicants at all concentrations significantly reduced root system length of T. aestivum seedlings relative to the control (from 69% to 25 times).
- Intervention effect Both toxicants at all concentrations significantly reduced shoot height of T. aestivum seedlings relative to the control by 25–76%.
- Intervention effect Both toxicants increased the intensity of lipid peroxidation in T. aestivum seedling shoots, indicating a stress reaction.
- Intervention effect Heavy metal salt concentrations lethal for T. aestivum caused almost no disturbances of the studied parameters in P. sativum seedlings.
- Intervention effect Lead nitrate exposure decreased root system length in P. sativum seedlings.
- Observation P. sativum seedlings were much more resistant than T. aestivum to the tested concentrations of lead nitrate and copper sulfate.
