Abstract
Two maize genotypes(Zhengdan958 and Hudan4) with different drought tolerance were screened to study the effects of yield and water use efficiency (WUE) under drought stress and re-watering in different growth stages.The results showed that the yield decreased in both varieties under drought stress and re-watering in any growth stages,par-ticularly drought stress in the flowering stage.WUE in both varieties also reached the minimum under drought stress and re-watering in the flowering stage.Among the varieties,the yield and WUE of Zhengdan958 was higher than Hudan4 in every treatment.The water consumption was basically the same.The plant height,leaf area index(LAI) and biomass of two varieties gained compensation during the recovery stage,but the compensation of Zhengdan958 was significant-ly stronger.Therefore,it was considered that under drought stress and re-watering Zhengdan958 had more strong compensation ability,thereby attaining a higher yield and WUE.
