Other claims from this paper (6)
- Intervention effect Exposure of zucchini plants to Ni significantly altered growth.
- Observation Ni accumulation was higher in the shoots (1314 µg g-1 DW) than in roots and fruits.
- Intervention effect Flavonoid content decreased in the roots and shoots in response to Ni treatment.
- Mechanism Nickel tolerance in C. pepo is ensured by a combination of mechanisms such as increased proline content.
- Observation The species survived and tolerated toxic Ni concentrations up to 500 µM to different degrees, with visible toxicity symptoms such as leaf chlorosis.
- Observation Based on hyperaccumulation thresholds, Cucurbita pepo can be qualified as a nickel hyperaccumulator species.
