Other claims from this paper (9)
- Intervention effect Hyperhydric apple leaves showed abnormal, often discontinuous development of the epidermis and cuticle compared with healthy leaves.
- Intervention effect Hyperhydricity significantly lowered chloroplast number per cell compared with healthy leaves.
- Intervention effect Hyperhydricity reduced thylakoid stacking in chloroplasts compared with healthy leaves.
- Intervention effect Hyperhydricity decreased the concentrations of reduced and oxidized pyridine nucleotides.
- Mechanism The decrease in pyridine nucleotides is taken to reflect reduced metabolic activity in hyperhydric apple leaves.
- Intervention effect Activities of superoxide dismutase, catalase and ascorbate peroxidase were higher in hyperhydric leaves than in healthy leaves.
- Association Hyperhydricity was associated with oxidative stress.
- Intervention effect Photochemical efficiency of photosystem II, effective quantum efficiency and photochemical quenching were lower in hyperhydric leaves than in healthy leaves.
- Association Hyperhydricity was associated with oxidative damage to the photosynthetic machinery.
