Effect of Drought Stress on Some Physiological Traits of Durum (Triticum durum Desf.) and Bread (Triticum aestivum L.) Wheat Genotypes

Drought is a wide-spread problem seriously influencing wheat production and quality worldwide. We aimed to study adaptive changes in physiological parameters of 6 durum and 7 bread wheat genotypes under drought stress. Water stress caused reduction of leaf gas exchange parameters-photosynthesis rate, stomatal conductance, intercellular CO₂ concentration, transpiration rate as well leaf area, dry mass, relative water content, and chlorophyll content. Photosynthesis rate, chlorophyll content were higher in flag leaf of bread wheat genotypes. Photosynthesis rate positively correlated with leaf area, dry mass and relative water content.
