![]() Mowing treatments were made during active turfgrass growth to 5-foot by 10-foot plots arranged in a randomized complete block with four replications. Zoysiagrass was mowed at 0.25 inch two days per week, 0.5 inch two days per week and no mowing. The bermudagrass and seashore paspalum fields included mowing at 0.25 inch two days per week, 0.5 inch two days per week, 1.5 inches weekly, and no mowing (Figure 1). In addition, the grasses were mowed at various regimens to further evaluate the influence of mowing operations on seedhead production.įigure 1 Plots of Sea Isle 1 seashore paspalum used for seedhead production experiments that were mowed at various heights from 2012 to 2015. The experiments were initiated to help determine the environmental factors that trigger initial seedhead emergence of these grasses and the association with seasonal seedhead production. Photoperiod is defined as the number of hours of daylight per day. Most PGRs don’t provide acceptable control of seedheads after emergence at rates with limited injury potential to golf course turfgrass.įield experiments were conducted at the University of Georgia Griffin campus from July 2012 to December 2015 to determine the influence of photoperiod and temperatures on seedhead production of TifGrand bermudagrass, Sea Isle 1 seashore paspalum and Diamond zoysiagrass. Growth suppression with PGRs of grasses prior to seedhead development delays inflorescence more effectively than applications after emergence. The use of PGRs also may enhance tillering and root growth, which often is compromised during seedhead production. Suppressing seedhead emergence of these grasses enhances aesthetics, functionality and ball-roll distances for long-term successful culture.Ĭontrolling seedheads with plant growth regulators (PGRs) helps superintendents maintain turfgrass uniformity. This cultivar produces seedheads during the spring and fall but has limited-to-no seedhead production during summer months. ![]() Diamond zoysiagrass (Zoysia matrella (L.) Merr.) is a fine-textured cultivar that may be used for greens, tees and fairways. These cultivars produce seedheads throughout the growing season under various mowing heights and maintenance regimens. transvaalensis Burtt Davy) and Sea Isle 1 seashore paspalum (Paspalum vaginatum Sw.) are popular selections for golf course fairways, tees and roughs. TifGrand bermudagrass (Cynodon dactylon (L.) Pers. Seedheads reduce the aesthetics and quality of golf course turfgrass.
