| Abstract/Contents: | "Limited availability of water for future use and increased cost associated with irrigating turf underscore the need to conserve irrigation waster in New England. To that end maximizing turfgrass quality and function with less water can be achieved through enhanced drought avoidance adaptations such as deep rooting and shoot characteristics that reduce turfgrass evapotranspiration (ET) or water use rates. Research to identify specific drought avoidance adaptations (shoot and root aspects) and their relative importance to drought survival in cool-season turfgrass such as Kentucky bluegrass is limited, however, important to developing resistant cultivars and effective management strategies. In this study drought survival (indicated by percent green cover, wilting tendency, turfgrass quality, and leaf-to-air temperature differences) during summer dry-down will be assessed in field plots comparing 12 Kentucky bluegrass cultivars representing six low-water use and six high-water use genotypes (see Table 1). Such comparisons may be useful in determining the significance of low water use in delaying or postponing drought stress injury. Cultivar rooting potential by soil depth evaluated in greenhouse and field plot studies will be assessed as potential selection criteria for improved drought survival and will be compared with shoot aspects including cultivar ET and water use efficiency (WUE). It is hopeful that rooting characteristics when considered in combination with shoot components (ET, WUE) will provide greater predictive value and efficient screening for genotypes possessing superior drought resistance." |
