Abstract/Contents:"The objective of this investigation was to determine the leaf blade stomatal densities of 10 warm season turfgrasses, encompassing 9 species, and their evapotranspiration (ET) rates under non-limiting soil moisture conditions. Three replicates of each turfgrass were established onto a fritted clay root zone via turfed plugs and established for 9 months under greenhouse conditions. Stomatal characterizations were made from polyvinyl leaf impressions counted at 200X magnification. Assessments of ET rate were based on lysimeter measurements made over a 24-hour period in a specially designed controlled environmental simulation chamber. Significant differences in stomatal density were found among the 10 warm-season turfgrasses on both the abaxial and adaxial leaf surfaces. Turfgrasses in the Eragostoideae subfamily had higher stomatal densities than turfgrasses in the Panicoideae subfamily. The stomatal densities were considerably greater than those reported for cool-season turfgrasses. The relative ranking of ET rates under non-limiting soil moisture were: Emerald zoysiagrass (Zoysia Japonica x Z. tenuifolia Willd. ex Trin.), highest; Texas Common St. Augustinegrass (Stenotaphrum secundatum Walt. Kuntze), Adalayd seashore paspalum (Paspalum vaginatum Sw.), Meyer zoysiagrass (Z. japonica Steud.) and Argentine bahiagrass (P. notatum Flugg.), intermediate; Georgia Common centipedegrass (Eremochloa ophiuroides Munro. Hack), intermediate-low; and Tifway, Tifgreen, and Arizona Common bermudagrasses (Cynodon spp.) and Texas Common buffalograss (Buchloe dactyloides Nutt. Engelm), lowest. As a group, the ET rates of the warm-season turfgrasses were lower than those reported for cool-season turfgrasses. The lack of a positive relationship between ET rate, under non-limiting soil moisture, and stomatal density indicates that breeding programs designed to develop water conserving warm-season turfgrasses should place priority on other plant parameters such as increased canopy resistance and decreased leaf area."
