title: Effects of Powdery Mildew and Water Stress on CO(2) Exchange in Uninfected Leaves of Barley.
abstract: Net photosynthesis is stimulated in third seedling leaves of barley plants whose lower two leaves are heavily infected by Erysiphe graminis f.sp. hordei Marchal. Stimulation is greater in water-stressed than in well-watered plants. In stressed, but not in well-watered plants, stimulation is associated with the maintenance of high leaf water potential and high leaf conductance. A small part of the changes in net photosynthesis is attributable to changes in respiratory metabolism in the third leaf, and other possible causes are discussed.
