Other claims from this paper (7)
- Intervention effect Drought stress significantly increased SOD, CAT and GPX activity in sunflower compared with control plants.
- Intervention effect Higher potassium levels significantly decreased SOD, CAT and GPX activity in sunflower compared with control plants.
- Intervention effect Higher potassium levels significantly decreased MDA in sunflower compared with control plants.
- Intervention effect Sunflower plants with higher potassium levels showed higher resistance to drought stress.
- Intervention effect Sunflower plants with higher potassium levels had higher yield and higher dry matter allocation to grain filling (harvest index).
- Mechanism The authors suggest drought stress leads to production of oxygen radicals, which increases lipid peroxidation (MDA) and oxidative stress in the plant.
- Mechanism The authors conclude that the scavenging system, especially SOD, CAT and GPX, worked well and membrane damage (MDA) was controlled at higher potassium levels.
