| Abstract/Contents: | "Mesotrione, topramezone, and tembotrione inhibit 4-hydroxyphenylpyruvate dioxygenase (HPPD), an enzyme integral to carotenoid biosynthesis. Research was conducted to evaluate the efficacy of visual bleaching and chlorophyll fluorescence yield (Fv/Fm) measurements for estimating common bermudagrass [Cynodon dactylon (L.) Pers.] carotenoid and chlorophyll concentrations following mesotrione (0.28, 0.35, and 0.42 kg ha-1), topramezone (0.018, 0.025, and 0.038 kg ha-1), and tembotrione (0.092, 0.184, and 0.276 kg ha-1) applications. Measurements of VB and Fv/Fm were evaluated 3, 7, 14, 21, 28, and 35 d after application. Leaf tissues were sampled on the same dates and assayed for chlorophyll and carotenoid compounds by using high-pressure liquid chromatography methodology. Carotenoid and total chlorophyll concentrations were regressed upon VB and Fv/Fm on each evaluation date. While significant (P < 0.05) relationships were detected on each date, variation explained by linear regression was modest (R2 < 0.65); thus, neither VB nor Fv/Fm assessments are good predictors of carotenoid and chlorophyll concentrations after HPPD-inhibiting herbicide treatment. Comparisons of R2 values for VB and Fv/Fm data suggest no advantage in using Fv/Fm in place of VB measurements when evaluating HPPD-inhibiting herbicide activity." |
