Frequency of powdery mildew resistances in spring barley cultivars in Czech variety trials

Induction of Disease Symptoms in Barley by Powdery Mildew.

Powdery millews usually grow superficially on their hosts but produce symptoms of disease throughout the underlying host tissues. The symptoms include marked increase in respiratory rate (1, 3, 15. 24, 26, 30. 35); accumulation of organic and inorganic substances (1,29, 36): increase in dry weight (10. 26) ; increase in wet weight (3) decrease in photosynthesis when the disease is well develope...

Effects of Powdery Mildew and Water Stress on CO(2) Exchange in Uninfected Leaves of Barley.

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 t...
