This study was conducted to evaluate the effect of plant growth inhibitors on "Penncross" creeping bentgrass in the green of golf course for increasing the summer quality. Chlormequat chloride (C) 250$ imes$, 500$ imes$, 1000$ imes$, daminozide (D) 50$ imes$, 100$ imes$, 200$ imes$, paclobutralzol (P) 1000$ imes$, 2000$ imes$, 4000$ imes$, trinexpac-ethyl (T) 1000$ imes$, 2000$ imes$, 4000$ imes$, uniconazole (U) 25$ imes$, 50$ imes$, 100$ imes$ with three concentrations, respectively, were applied to creeping bentgrass. The leaf length, leaf width, and internode length of stolon were inhibited by all plant growth retardants applied as compared to that of control in which D-50, T-2000, and trinexpac-ethyl were the most effective among treatments on the inhibition of leaf length and internode length of stolen, respectively. Leaf thickness increased more in the treatments of C-250, D-50. T-2000 and T-4000 than any other treatments. On the other hand, shoot density which was represented by number of leaves per unit area was found to be the highest in P-2000 and P-4000 treatment. In this case, all plant growth retardants with no significant differences showed increase of 15-20% in density as compared to control. Total dry weight increment was higher in P-2000 and P-4000 while leaf dry weight increment was higher in T-4000. and U-25 and 50 than other treatments. According to the visual evaluation for the purpose of turf quality measurement, it was found that paclo-butralzol, trinexpac-ethyl and uniconazole were not suitable for green maintenance and extension because of making leaves to yellow. In conclusion, it was postulated that C-250, D-50, and T-4000 had possibility to use practically in the green area of golf course.lf course.
