- Intervention effect Drought stress reduced relative water content and above- and below-ground biomass in maize.
- Intervention effect Drought stress reduced rates of photosynthesis and protein content in maize.
- Intervention effect Drought stress severely affected maize morphology.
- Intervention effect The prolonged water deficit increased relative membrane permeability and oxidative stress in maize.
- Intervention effect The prolonged water deficit increased malondialdehyde production, lipoxygenase activity (LOX) and H2O2 production in maize.
- Intervention effect The single applications of MeJA and SA were not effective for drought tolerance in maize.
- Intervention effect The combined MeJA+SA pre-treatment mitigated drought-induced oxidative stress in maize.
- Intervention effect The combined MeJA+SA pre-treatment lowered levels of lipid peroxidation, LOX activity and H2O2 under drought in maize.
- Intervention effect The MeJA+SA pre-treatment increased osmolytes including proline, total carbohydrate content and total soluble sugars under drought in maize.
- Intervention effect The MeJA+SA pre-treatment maintained adequate water status of maize plants under drought.
- Intervention effect Exogenous MeJA+SA approximately doubled the activities of catalase, peroxidase and superoxide dismutase in maize.
- Intervention effect Pre-treatment with MeJA alone gave the highest increase in drought-induced endogenous abscisic acid production in maize.
- Mechanism MeJA+SA pre-treatment partially prevented drought-induced oxidative stress by modulating endogenous ABA in maize.
