Abstract
Infection by a compatible race of Erysiphe graminis f. sp. hordei on b arley secondary leaves was significantly suppressed upon pruning of th e primary leaves when E. graminis hordei was inoculated 3-12 h after t he pruning, but it was rather enhanced during 15-21 h. The accumulatio n of antifungal substances was detected in hot ethanol extracts of bar ley seedlings from 15-27 h after pruning the primary leaves. Taking th e time of the infection process of a challenger (E. graminis hordei) i nto consideration, timing of systemic resistance induced upon pruning coincided with the accumulation of antifungal substances.
