Abstract/Contents:"Effects of mefluidide at the rate of 384 mg/m², paclobutrazol at the rate of 20 mg/m², and equal mix of mefluidide plus paclobutrazol at the rate of 288 and 7.5 mg/m², respectively, on shoot and root growth and quality of perennial ryegrass (Lolium perenne L. cv. Wendy) and creeping red fescue (Festuca rubra L. cv. Dawson) were tested under container culture. Mefluidide applied alone or in combination with paclobutrazol caused significant reduction in shoot and root growth of both perennial ryegrass and red fescue. The same treatments, also, enhanced turfgreen color of both turfgrasses and increased the percentage of their root/shoot dry weight. Although these treatments reduced the quality of both turfgrasses, the quality was within the range accepted for home lawn turf. Paclobutrazol applied alone reduced shoot height of perennial ryegrass and red fescue by 10% and 32% respectively. Whereas, it caused little reduction in their shoot weights and had no effect on turf quality and color. Paclobutrazol alone reduced root length of both turfgrasses, but it did not affect the percentage of root/shoot dry weight of red fescue. Paclobutrazol alone gave better root system distribution for both turfgrasses than mefluidide alone and mefluidide plus paclobutrazol, which caused the majority of the roots of perennial ryegrass and roots and rhizomes of red fescue to grow in the top 10 cm segment of the container media."
