e1“Under severe drought, maize exhibited reductions up to 67.3% in stem dry mass, 68.1% in net photosynthesis, and 63.9% in grain yield, compared to 47.4%, 53.6%, and 54.6% reductions in sorghum, respectively”

- Intervention effect Under severe drought, sorghum stem dry mass was reduced by 47.4%.
- Intervention effect Under severe drought, sorghum net photosynthesis was reduced by 53.6%.
- Intervention effect Under severe drought, sorghum grain yield was reduced by 54.6%.
- Intervention effect Drought significantly reduced biomass and photosynthetic efficiency in maize and sorghum.
- Intervention effect Drought significantly reduced yield traits and grain quality indices in maize and sorghum.
- Association Sorghum showed smaller drought-induced reductions than maize.
- Association Sorghum showed lower oxidative damage under drought.
- Association Sorghum showed higher osmolytes, flavonoids and phenols under drought.
- Association Sorghum showed higher polyphenol oxidase (PPO) under drought.
- Intervention effect HA priming enhanced biomass accumulation and photosynthesis under drought in maize and sorghum.
- Intervention effect HA priming enhanced osmolyte production and non-enzymatic and enzymatic antioxidants under drought.
