| Abstract/Contents: | "The objective of this study was to determine the effects of two plant growth regulators (PGR) and two soil moisture levels (SML) on evapotranspiration (ET), leaf extension rate (LER), and visual turf quality of Texas Common St. Augustinegrass grown under glasshouse conditions in plastic minilysimeters, measuring 22 cm diam and 21.5 cm deep containing fritted clay. Turf coverage and full, uniform and rooting well established prior to treatment application. The three PGR treatments were flurprimidol (0.84 kg ha-1), mefluidide (0.42 kg ha-1), and no PGR; grown at optimal SML (-0.01 MPa) and suboptimal SML (-0.8 MPa). Application of either PGR at either SML reduced ET by an average of 18%, but the duraton of significant activity changed due to selection of PGR and SML. Duration of significant ET reduction was 3 and 5 weeks for mefluidide and 5 and 15 weeks for flurprimidol, at optimal and suboptimal SML respectively. Application of either PGR at either SML caused a reduction in LER by an average of 83%, but the duration of significant activity changed due to selection of PGR and SML. Duration of significant LER reduction was 4 and 5 weeks for mefluidide and 8 and 17 weeks for flurprimidol, at optimal and suboptimal SML, respectively. Flurprimidol was a more effective PGR, but its longer duration of reduced turfgrass quality was a drawback. Both PGR's were more effective at the suboptimal SML." |
