Abstract

In the investigated barley cultivar resistant toErysiphe graminis f. sp.hordei Marchal a temporary decrease in water uptake may be observed during the first days following infection in light. No marked differences could be detected in darkness. Starting from the stage of formation of fructification organs the ratio between water uptake in light and in darkness in the resistant cultivar is similar to that of the control, while the opposite is true in the susceptible cultivar where the ratio markedly decreases with the development of powdery mildew. The resistant cultivar responds more rapidly to the pathogen by changes in water uptake than the susceptible one.
