Abstract/Contents: | Presents a study with the following objectives: "1. Develop and implement a salinity tolerance screening procedure that a) provides salinity tolerance of seashore paspalum ecotypes under well-watered and drought stress, b) allows 3 salinity tolerance screening protocols to be assessed for efficiency in separating seashore paspalum ecotypes and for establishing a 'standard' protocol, and c) provides detailed data on seashore paspalum ecotype root tolerance data on the edaphic (soil) stresses of salinity, drought, and drought + salinity. 2. Determine seashore paspalum ecotype tolerance to the multiple root stresses in the acid soil complex (soil strength, drought, nutrient deficicencies, element toxicities, high soil/air temperatures) that strongly influence drought resistance via drought avoidance from deep rooting. 3. For nine seashore paspalum ecotypes with the greatest potential for release, to determine relative to Tifway bermudagrass overall drought resistance, rooting, shoot performance, and water use (ET)/soil extraction patterns under close-cut fairway conditions." States that "for maximum multiple root stress tolerance and potential for good performance under adverse soil/drought conditions a turfgrass should: (a) have an acceptable, inherent growth rate under the low pH conditions, and (b) exhibit a low pH/high pH growth ratio that is near 1.0." Notes that "seashore paspalums with a low pH/high pH ratio of ā„ 1.0 are particularly strong in tolerance to the 'acid soil complex' stress." The ecotypes "exhibiting this trait were: PI 509022, Temple 2, HI 101, PI 509021, and Fidalayel." This three-year study began in 1998. |
