Drought stress in winter wheat - physiological responses and detection using remote and proximal sensing techniques

Abstract

The effects of drought stress on wheat grain yield depend on the severity and duration of the stress, and the response varies depending on the phenophase of the crop. Drought stress affects leaf area expansion, dry matter distribution, photosynthetic rate, and root growth. Remote and proximal sensing of vegetation (RS and PRS) provides a non-destructive method suitable for rapid and accurate assessment of plant physiological responses to stress factors including drought.
