Abstract/Contents:Presents two studies to evaluate seeded bermudagrasses "for shoot aspects (quality, density, color), rooting, and water use." Results of the first study indicate that "none of the experimentals have exhibited any winter injury in spring 94 or 95...Cultivars with higher visual quality than AZ Common were 91-15 (53% of ratings) and 91-3 (27%); greater shoot density than AZ Common were 91-15 (87%), 91-3 (33%), 91-2 (33%) and 91-1 (27%); better color than AZ Common were 91-3 (75%), 91-4 (63%), 91-14 (50%), 91-2 (38%) and 91-12 (38%)...Cultivars that are most responsive to increasing N are 91-4, 91-2, 91-10, AZ Common, 91-12, and Primavera. While 91-3 was not responsive to increasing N, it developed good quality, density, and color even at the lowest N...In 1994, the best traffic tolerance for wear + compaction (WC) and soil compaction (C) was demonstrated by 91-15, 91-1, and 91-2...Two of the genotypes lost roots over the summer; namely 91-12 and 91-1. Those genotypes exhibiting greatest rooting in last summer were 91-15 and 91-14." Results of the second study indicate that "under routine traffic from mowing ('none' traffic), best overall performance was noted for Tropica, J-32 (once fully established), FMC-2-90, Cheyenne, and Primavera. When traffic was imposed with the studded roller, cultivars with the best traffic tolerance were Tropica, Cheyenne, and J-32...The best early summer rooting (June) was observed on Tropica and Primavera. By late summer (late Aug./early Sep.), Tropica and J-91 had highest root growth in the 12 to 24 inch zone for both years...Evapotranspiration (ET) rates based on 6-day dry down cycles and averaged over all measurement periods ranged from 3.0 (Sonesta) to 4.6 mm d-1 (AZ Common)...Primavera (3.1 mm d-1) and Tropica (3.4 mm d-1) appeared to have inherently low ET rates, while Sonesta exhibited low ET in late summer due to poor deep root growth. During a late summer dry-down in 1994, NuMex Sahara exhibited leaf firing to a greater degree than other cultivars, while Tropica had the least."
