| Abstract/Contents: | Selected experimental growth retardants were tested in the field and greenhouse to determine their effects on developmental morphology of 'Merion' Kentucky bluegrass. EL-500, PP-333, and MBR 18337 were compared to untreated controls plus samples treated with a standard rate of mefluidide. Analyses included measurements of turfgrass height, leaf weight, seedhead suppression, tiller formation, and turf color. Growth retardants were sprayed on 0.9 x 2.1 m field plots in early May of 1981. All plots were mowed 2 days before and 10 days following treatment. For greenhouse trials, similar-sized individual tillers of the grass were transplanted into a sand:peat (5:3) mixture contained in 16 oz styrofoam cups. Retardants were sprayed onto the surface of the developing grass leaves 4 weeks after transplanting. Quality ratings of both field and greenhouse plants were taken weekly. All the experimental chemicals reduce grass growth as compared with untreated controls with PP-333 being the most effective. Leaf weight was reduced under all growth retardants in both the greenhouse and field trials. Tiller formation was increased in grass samples treated with the experimental growth retardants as compared with untreated controls and mefluidide. Quality of the treated turfs, as rated by seedhead suppression, leaf color and plant density, indicated that the experimental growth retardants reduced turf appearance. Although the tested growth retardants did stunt grass development, each one caused a yellowing of leaf tissue and failed to suppress seedhead formation, making them currently unsuitable for use on fine turf. Combinations of EL-500 and PP-333 with mefluidide could suppress seedhead formation but did not alleviate turf discoloration. |
