| Abstract/Contents: | "Quality of cool-season turfgrasses declines in Japan during the summer and it is not well understood whether this is due to heat stress or flooding. This experiment was designed to select flood tolerant cultivars of perennial ryegrass, tall fescue and Kentucky bluegrass and heat tolerance of the same cultivars for several temperature regimes ranging from 36-50 C and to find whether heat or flooding causes the decline in the turf quality in Japan. Seeds were planted in the pots filled with sand and plants were grown outside. Flood stress was imposed by blocking drainage holes of the pots with rubber stoppers after plants were established and flooding was continued from fall until end of the summer. Heat stress evaluation was conducted in a controlled environmental growth chamber programmed to impose temperatures and conditioned for about three weeks in the chamber. Cultivars were not markedly affected by flooding or flood duration from fall until early summer, but most of them were heavily damaged when flooding prolonged into the summer. The most flood tolerant cultivars were Asset and Haga, All Star and Premier, and Arid and Maveric for Kentucky bluegrass, perennial ryegrass and tall fescue, respectively. Initial heat injury occurred to perennial ryegrass at 36 C and others at 42 C. Nugget and Bristol, Pinnacle and All star, and Rebel Jr. and Mesa were the most heat tolerant cultivars among the Kentucky bluegrass, perennial ryegrass, and tall fescue cultivars, respectively. Cultivars of perennial ryegrass like Pinnacle and All Star survived 42 C, whereas cultivars of Kentucky bluegrass including Nugget and Bristol and tall fescue such as Rebel Jr. and Mesa survived 48 C. Therefore, it is suggested that direct high-temperature or flooding alone doesn't cause significant damages to such turfgrasses in Japan, but when flooding occurs under high temperature these species are damaged perhaps due to reduction in their transpirational cooling." |
