Figure 1. Effects on visual quality rated on a scale of 1 to 9 (1 = poorest and 9 = highest) of (A) high temperature, (B) drought, (C) high temperature and drought, and (D) control in Kentucky bluegrass (KBG), hybrid bluegrass (HBG), and tall fescue (TF). Symbols along the abscissa of each graph indicate significant differences (P = 0.05) between HBG and KBG (*), HBG and TF (+), and KBG and TF (x), on a given day after treatment initiation (days of treatment).
