| Abstract/Contents: | "As potable water available for turfgrass irrigation deceases, water conservation and deficit irrigation have received increasing attention in recent years. This study was conducted to determine responses of creeping bentgrass (Agrostis stolonifera L.) and Kentucky bluegrass (Poa pratensis L.) to deficit irrigation and influence of foliar application of glycinebetaine on turfgrass performance. Three irrigation regimes were used, including replacement of 100%, 85%, and 70% of actual evapotranspiration (ET). Glycinebetaine was applied to foliage of both species at 3.8 kg ha-1 monthly. Soil moisture content, turfgrass quality, ET rate, root growth characteristics, and leaf cytokinin content (zeatin riboside) was determined. Irrigation at 85% ET did not affect turfgrass performance. Irrigation at 70% ET decreased soil moisture content, ET rate, root growth, and visual quality in Kentucky bluegrass, but not in creeping bentgrass except for root growth, when compared with 100% ET irrigation. The data indicated that irrigation could be reduced by 30% in creeping bentgrass and 15% in Kentucky bluegrass without negative turfgrass quality responses. Glycinebetaine significantly increased root surface area, root biomass, and leaf cytokinin content in creeping bentgrass, while the only response in Kentucky bluegrass was an increase in root biomass. The results suggest foliar application of glycinebetaine may be considered as a supplemental approach to improve turfgrass persistence under deficit irrigation, especially for creeping bentgrass maintained at fairway height." |
