STUDIES OF RECOVERY FROM ARTIFICIALLY INDUCED LODGING IN SEVERAL SIX-ROW BARLEY CULTIVARS

摘要: Artificial lodging treatments were applied to several six-row barley cultivars (Hordeum vulgare L.) in 1985 and 1986 field plots at the University of Alberta Research Station, Edmonton, determine effects from milk stage maturity. For all largest significant reduction grain yield was obtained induced (average 21% reduction), with later resulting relatively less (4% preharvest). Significant on thousand-kernel weight hectoliter followed same pattern. Incidence disease (mainly scald) significantly increased by induction one two years. Final scores maturity higher that induced, associated generally reduced ability recover lodging. In 1 year testing, semidwarf cultivar Duke found be superior Samson for resistance, ...
