The responses of six wheat genotypes to water stress were analysed. Soil moisture (H), leaf water potential (?w), photosynthesis (PN), stomatal resistance (rs) and transpiration (T) were measured during a water stress. The genotypes investigated differed in their stress avoidance (?w-H relationship) and their stress tolerance (PN-?w and rs-?w relationships). The most important differences observed concern the mechanisms of tolerance at low leaf water potential: two varieties, Haurani 27 and Baalback, can then maintain a high photosynthetic activity. These observations are in agreement with the drought resistance characteristics already known for these genotypes. Possible applications to wheat breeding are considered |
