| Abstract/Contents: | "This study was conducted to determine the effect of root zone cooling on growth and quality of turfgrass including Kentucky bluegrass (Poa pratensis L. 'Nuglade'), perennial ryegrass (Lolium perenne L. 'Accent'), tall fescue (Festuca arundinacea Schreb. 'Pixie'), and Japanese lawngrass (Zoysia japonica Steud.) in simulated athletic field during summer season in Korea. Mineral contents in clippings of turfgrass grown at different soil mixtures and temperatures were also analyzed. Root zone cooling (approximately 4~6°C lower than that of untreated-control) resulted in good uniformity, little disease incidence and higher level of chlorophyll contents in cool-season turfgrasses. The effectiveness of root zone cooling in protecting disease incidence from high temperature stress was the most manifest in perennial ryegrass compared to others. Fresh clipping weight in treatment of root zone cooling was increased approximately 2 times in Kentucky bluegrass and perennial ryegrass, and 2.5 times in tall fescue compared to those of control. There was higher growth rate in a soil mixture composed of 80% peat moss + 10% sand + 10% soil (v/v/v) than in that of 80% pea moss + 20% sand (v/v). Mineral contents of N, P, K, Ca, and Mg in clippings of three species of cool-season turfgrass were significantly increased in treatment of root zone cooling but this was not found in Japanese lawngrass. Results showed that root zone cooling has a benefit in keeping good quality and growth of cool-season turfgrasses' in sports field under supraoptimal ambient temperature during summer season." |
