Title
Physiological and Biochemical Changes Induced by PRD Irrigation in Four Olive Varieties

Other claims from this paper (7)
- Intervention effect Partial root-zone drying gave an earlier maturity of olive fruit than the control.
- Intervention effect Partial root-zone drying gave higher olive fruit weight in Manzanilla, reaching 7.1 g, than the control.
- Intervention effect Partial root-zone drying gave higher olive fruit dimensions in Manzanilla, reaching 2.6 cm, than the control.
- Intervention effect Partial root-zone drying up-regulated soluble peroxidases (POX), insoluble peroxidases (POXins) and polyphenoloxidase (PPO) in olive compared with the control.
- Intervention effect Partial root-zone drying up-regulated superoxide dismutase (SOD) in olive compared with the control.
- Observation Picholine Marocaine and Haouzia olive varieties showed higher enzymatic activities than the other varieties under partial root-zone drying.
- Mechanism Partial root-zone drying possibly induced oxidative stress, which up-regulated antioxidant activities of POXins, POX, PPO and SOD under water deficit.
