| Abstract/Contents: | Presents a study conducted to "determine several physiological effects of PGRs [plant growth regulators] on turfgrass growth." Details methods and materials used in the study, stating that "studies were conducted at the Landscape Horticulture Research Center on the University of Illinois - Urbana campus and in controlled environment growth chambers." Reports that "Primo Maxx and Trimmit 2SC are degraded more rapidly at higher temperatures...The shorter the half-life (the time, measured in days, for the concentration of the PGR in the plant to be reduced by half), the faster the rate of degradation...The effects of PGRs on photosynthesis appear minimal...Primo Maxx had no effect on photosynthesis at any measurement time...Trimmit 2SC initially reduced photosynthesis at one week after treatment, but that reduction was statistically significant only in the spring...The data indicate that these PGRs have minimal (Trimmit 2SC) to no (Primo Maxx) effect on plant photosynthesis. Thus, these products are true regulators and not growth retardants. Treatment with a PGR will increase tillering, but in the first week after application the turf will look less dense as leaf elongation is slowed and plant energy is redirected to tillering." Concludes that "PGRs have become widely used management tools that offer superintendents many benefits, including increased turf color, reduced leaf extension...and increased density and uniformity. Having a better understanding of the effects of these PGRs will enable superintendents to make better use of these products." |
