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”
e2“Drought stress significantly reduced biomass, photosynthetic efficiency, yield traits, and grain quality indices in both species, with sorghum consistently demonstrating smaller reductions”
