| Abstract/Contents: | "Applied to turf, the plant growth regulator trinexapac-ethyl (TE; PrimoMAXX®, Syngenta) offers prospects for reduced leaf elongation, enhanced tillering, darker green colour,and better resistance to drought and shade (Erwin and Zhang, 2008). These physiological changes may not only improve the aesthetic and functional quality of golf course playing surfaces, but they have also been shown reduce CO2 emissions by 39-58% and maintenance costs by 4-21% (Bartlett and James, 2009). In Scandinavia, i.e. at latitudes ranging from 55 to 71 ºN, turfgrasses are exposed to longer photoperiods with lower light intensities and lower red to farred (R/FR) ratios than in countries further south. The turf responds to these light conditions by allocating more resources to leaf elongation and less to tillering and carbohydrate storage. As these responses are partly mediated by gibberellic acid (GA) (Heide, 1985), the application of TE, an inhibitor of the conversion from inactive GA20 to bioactive GA1, may well be particularly advantageous at high latitudes. Thus, our objective was to study turfgrass responses to TE on golf course greens and fairways in Scandinavia." |
