Abstract/Contents: | "Our objective is to determine if monthly applications of trinexapac-ethyl to an actively growing zoysiagrass experimental fairway will enhance quality under two levels of dense shade." Plots of 'Meyer' zoysiagrass were maintained under three light levels (full sun, 73% shade and 92% shade) and three rates of trinexapac-ethyl (0.0, 0.125 and 0.25 oz/1000 square feet). Shaded zoysiagrass not treated with trinexapac-ethyl displayed greater vertical shoot growth (measured as clipping weight) than unshaded grass; however, treatment with trinexapac-ethyl reduced growth of shaded grass to the same level as that of untreated, unshaded grass. Shaded grass treated with trinexapac-ethyl also had higher quality than untreated, shaded grass. It is suggested that the increase in quality is due to reduced energy expenditure, arising in turn from reduced gibberellic acid activity in grass treated with trinexapac-ethyl. |
