Effects of Inundation on Six Varieties of Turfgrass.
Abstract
Six cold-adapted grasses, (manchar brome, boreal red fescue, durar fescue, nugget Kentucky bluegrass, meadow foxtail and sydsport bluegrass) were given ten-day dark and inundation stress treatments. Nugget Kentucky bluegrass grown in soil or gravel exhibited the best survival. Sydsport bluegrass did well in gravel. Meadow foxtail and manchar brome survived the treatments when grown in silt soil, but did not when grown on gravel soil. Rhizomes were regenerated by most of the grasses. Root transverse sections did not show any stress-related damage, but leaf sections did. The damage in the sections paralleled that observed macroscopically. Electrophoretic analysis for the peroxidase enzyme complex showed significant banding pattern differences before external damage was visible. This technique may prove to be a diagnostic tool for determining stress damage. Seedlings of all grasses except sydsport bluegrass survived a 15-day inundation. (Author)
