| Abstract/Contents: | "21 tall fescue cultivars were treated under simultaneous drought and heat stress in rain-shading greenhouse. Turfgrass quality was evaluated and leaf relative electrolyte leakage, relative water content, superoxide dismutase, catalase activity, and malondialdehyde content were measured. Results indicate that turfgrass quality, relative water content, superoxide dismutase, and catalase activity of each cultiva [cultivar] showed a decreasing trend, while leaf relative electrolyte leakage and malondialdehyde content showed an increasing trend. Moreover, the decreasing amount of relative water content, turfgrass quality, superoxide dismutase, and catalase activity and the increasing amount of leaf relative electrolyte leakage, and malondialdehyde content for Pixie, Tomcat, Fire phoenix, Ruby, Houndog V, Mustang II, and Arid III were lower (P<0.05) than those for Avalon, Apache, Arabia, and Triple yield, which suggest that the drought and heat stresses caused heavier injury to Avalon, Apache, Arabia, and Triple yield than other tall fescue cultivars. Through hierarchical clustering analysis, 21 tall fescue cultivars were clustered into three drought and heat resistance grades. Pixie, Tomcat, Fire phoenix, Ruby, Houndog V, Mustang II, and Arid III were clustered in the relative drought and heat resistance group; Crossfire II, Tulsa, Bingo, Barlexas, Olga, Gooden, Watchdog, Jaguar III, Safari, and Quest were the moderate drought and heat resistance group; Avalon, Apache, Arabia, and Triple yield were the low drought and heat resistance group. The results of the study will provide the theoretical evidence for turfgrass screening and introduction in arid regions." |
