Figure 6. Effects on (A) cumulative evapotranspiration (ET) (mm); (B) green leaf area index (LAI); and (C) degree-hours at the soil surface in high temperature, drought, high temperature and drought, and control treatments in Kentucky bluegrass (KBG), hybrid bluegrass (HBG), and tall fescue (TF). Means with the same letters in each graph were not significantly different (P = 0.05).
