| Abstract/Contents: | "Three experimental sites were selected for interseeding Crenshaw creeping bentgrass into existing Penncross putting greens including the Texas A&M University Research and Extension Center at Dallas, Brookhaven Country Club, and Dallas Country Club. Mechanical disruption and chemical suppression treatments were employed in a multiple-strip-split plot design. The most vigorous chemical suppressant was glyphosate and was used to allow easy visual determination of seedling emergence in dead bentgrass sod. Cimectacarb (Primo) and none chemical suppression treatments were also used. Mechanical disruption treatments were none, vertical mowing, core aerification, and star-tine aerification. Interseeding was accomplished during 1 through 15 April 1995. Visual observations within the glyphosate treatments indicate that vertical mowing may be the most effect means of mechanical disruption. However, overall seedling emergence was less than expected at all sites. This experiment was planted again in October 1995 at the Dallas Country Club. Electrophoretic analysis of isozyme banding patterns from samples collected from the TAMU-REC at Dallas location is providing, through close cooperation with Drs. M. C. Engelke and Ikuko Yamamoto, the necessary information to determine population changes. Current estimates of 10 to 20% contribution of Crenshaw produced from a single spring interseeding of this Penncross putting green provides the first quantified documentation that a new bentgrass cultivar can be successfully incorporated in an existing bentgrass putting green. Selection of maternal clones and populations to assess mechanisms of stress resistance has progressed with the assistance and close cooperation of Dr. Milt Engelke. Initial stress tolerance and stress tolerance mechanisms are being assessed in maternal clones. Progeny were obtained and increased to assess progeny response. The population(s) used will allow determination of the heritability of the various mechanisms of turgor maintenance or drought resistance and should provide insight into several mechanisms of bentgrass summer stress tolerance. Studies to determine the effects of blending bentgrass cultivars on bentgrass putting green turf quality, disease resistance, and performance were established at the Turfgrass Field Laboratory in College Station, Texas. These blending experiments will provide insight into the effects of creeping bentgrass blends on overall putting green quality. This concept is extensively use for other cool-season grasses, but has not been reported for creeping bentgrasses." |
