Physiological and Morphological Basis of Improved Water-Use-Efficiency in Wheat from Partial Root-Zone Drying

Water‐saving breeding and cultivation of winter wheat ( Triticum aestivum L.) have always been among the important missions in North China. But there is still a dispute on the regulation of water use in winter wheat. A pot experiment was conducted to investigate the physiological and morphological mechanisms of water use in two cultivars of winter wheat (KN9204 and drought‐tolerant LH2) via partial root‐zone drying (PRD). The results indicated...
