| Abstract/Contents: | "Trinexapac-ethyl [4-cyclopropyl- α-hydroxy-methylene)-3,5-dioxocyclohexanecarboxylic acid methyl ester] is a plant growth regulator used to reduce mowing, improve stress tolerance, and enhance turf quality. The mechanism of action does not appear to interfere with chlorophyll synthesis. However, chlorophyll may be more concentrated in leaves treated with trinexapac-ethyl, since leaf expansion is reduced. Chlorophyll contents and specific leaf weights increased with application of some plant growth regulators; however, the trinexapac-ethyl rate response to these properties is not well documented. Two greenhouse experiments were conducted to determine the influence of trinexapac-ethyl on the specific leaf weight and chlorophyll content of Poa pratensis L. Experimental design was a randomized complete block with 4 replications and a 2 (cultivars) x 5 (rates of trinexapac-ethyl) x 5 (days after treatment [DAT]) factorial arrangement of treatments. Total chlorophyll content increased by 26%, 48 days after treatment, with a single trinexapac-ethyl application of 0.45 kg ha-1. Chlorophyll contents were not significantly affected by trinexapac-ethyl treatment prior to 32 days after treatment. Specific leaf weights differed between the 2 cultivars of P. pratensis tested, but were not affected by trinexapac-ethyl. Increased chlorophyll content could allow treated P. pratensis to have higher light harvesting capabilities for photosynthesis and also may give improved visual color." |
