| Abstract/Contents: | "Four years of field drought resistance studies have been completed on a modified sand root zone. In the fourth year of the study 29 bermudagrass, 2 seashore paspalum, 2 buffalograss, 8 St. Augustinegrass, 6 centipedegrass, and 11 zoysiagrass cultivars were subjected to 158 days of progressive water stress with no supplemental irrigation applied and less than 7.5 cm of natural rainfall. Degree of leaf firing was used as an indicator of dehydration avoidance and post-drought shoot recovery was used as the indicator for drought resistance. Significant drought resistance differentials were found accross the cultivars and among the species. Results were consistent with the first three years of this study among the bermudagrass, seashore paspalum, St. Augustinegrass, and buffalograss cultivars. Among the centipedegrass cultivars only Oklawn fully recovered. Centennial, AC26, Tennessee Hardy, Georgia Common, and AC44 cultivars did not recover. Leaf firing of all zoysiagrass cultivars was in excess of 50%. All recovered, except Meyer at 20% and Belair at 45% after 30 days. Excellent dehydration avoidance was seen in Ormond, Franklin, NuMex Sahara, NMS-4, and NM-43 bermudagrass, in Adalayd seashore paspalum, and in Floratam, Floralawn St. Augustinegrass. Summary results indicate a very high to high classification as to drought resistance for bermudagrass, St. Augustinegrass, seashore paspalum, and buffalograss species, a high to medium rating for zoysiagrass species and low for centipedegrass species. There were highly drought resistant cultivars within each species for use in a non-irrigated, water stressed environment." |
