e1“Effects of toxic concentrations (up to 100 µM) of copper (Cu) and manganese (Mn) on growth and oxidative defense system of rice (Oryza sativa L.) and sunflower (Helianthus annuus L.) were studied under three light intensities in hydroponic medium”
e3“Higher light intensity strengthened the effect of toxicity of Cu while ameliorated that of Mn”

Other claims from this paper (11)
- Intervention effect Rice showed higher susceptibility to Cu and Mn toxicity than sunflower.
- Intervention effect Higher light intensity ameliorated the effect of Mn toxicity on rice.
- Intervention effect Cu toxicity increased ascorbate peroxidase and glutathione reductase activity in rice.
- Intervention effect Mn did not change or rather decreased ascorbate peroxidase and glutathione reductase activity in rice.
- Intervention effect Catalase activity was induced by both Cu and Mn, particularly under higher light intensities.
- Association Peroxidase activity was correlated with growth response of plants, unlike other tested enzymes.
- Intervention effect Copper was not effective in inducing malondialdehyde accumulation.
- Intervention effect Mn at 100 µM, causing no growth inhibition, significantly increased malondialdehyde.
- Association Tissue proline content changes were associated with stress conditions, similar to peroxidase activity.
- Association Peroxidase activity and proline accumulation tracked stress conditions but had no protecting role in plants.
- Association The antioxidant capacity of plants was not independently correlated with their growth response.
