Respiration and stem water potential ( psi ) were examined in parental and hybrid big sagebrush (Artemisia tridentata Nutt. ssp. tridentata and Artemisia tridentata Nutt. ssp. vaseyana (Rydb.) Beetle) grown in common gardens within each parental zone and in the hybrid zone. Plants were sampled in July, August, and September, i.e., immediately before, during, and after flowering. The habitats differed from one another, and there were significant garden by date interactions. The source populations also differed significantly from one another. There were no significant garden by source interactions. Hybrid plants had intermediate respiration rates and did not suffer greater water stress than parental plants. Hybrid plants showed no apparent decrease in adaptation in the important physiological traits respiration and water stress in the hybrid zone.Key words: Artemisia, hybrid zones, respiration, water potential.
