| Abstract/Contents: | "Mediterranean climate combines cold winters with drought and high temperatures in the summer. Southern Europe, with its typically Mediterranean climate, represents a transition zone for turfgrasses. During winter and intermediate seasons the cool-season turfgrasses can find good growing conditions, but in summer they suffer from heat stress. Warm-season turfgrasses can give high quality turfs in summer but as natural response to cooler temperatures and shorter day length they undergo a progressive decline in growth rate. When temperatures fall below 0 C warm-season turfgrasses develop a straw-brown color that persists from less than one month up to 5-6 months depending on location, species, cultivar and temperature trend (Volterrani et al., 1997). Considerable advantage would be gained, both from a technical and environmental perspective, by a more widespread utilization of warm-season turfgrasses. Where winter desiccation of warm-season turfgrasses is not tolerated for technical or aesthetic reasons, overseeding with cool-season turfgrasses is necessary. Use of turf covers or painting of turfs are considered secondary remedies to warm-season turfgrasses winter dormancy. Overseeding is carried out to: -provide live turf and color during winter; -improve playability of sports fields; -protect the dormant species against low temperatures; -reduce injury from traffic; file:///G|/Warm-season%20turfgrass%20overseeding.htm (1 di 11) [22/12/2004 16.08.19] OVERSEEDING (Schmidt and Shoulders, 1972; Turgeon, 1980; Hurley et al., 1989; Razmjoo et al., 1995). The ideal overseeding would rapidly establish a high - quality turf, maintain turf quality throughout the dormant period and provide a smooth transition back to warm-season grass in the spring. Major problems are associated with cool-season turfgrass establishment and removal. Other disadvantages of overseeding are: -increase of material, installation and maintenance costs; -inhibitory effect of cool-season turfgrasses on warm-season turfgrasses emergence and spreading in spring. Bermudagrass is denser if not overseeded (Volterrani et al., 2001a); -Poa annua and other winter active weeds can not be killed with non-selective herbicide; -Overseeding disease problems. From the agronomic point of view overseeding should not be carried out if the use of the turf is concentrated in the May-October period. In many golf courses the dormant period of warm-season turfgrasses is often tolerated in fairways." |
