The photographs were taken under cloudless conditions the afternoon of 13 July, using a 35-mm lens, with Kodachrome 64 film, F-stop=11 and 1/125th of second.  Transparencies were scanned to 4-MB TIFF files with a Polaroid Scanner, and the digital images opened in Adobe PhotoShop, tilted to parallel, brightness-adjusted +35 units, contrast adjusted to +30 units, uniformly cropped, and sized to 380 pixels width, and black plot borders added.  PhotoShop files were optimized with Ulead SmartSaver to JPEG quality level 60, no smoothing.

Originating at Wilderness Country Club in Collier County, Florida, PF-11 was discovered by Superintendent Paul Frank growing in a 328 (Tifgreen) green.  He propagated on numerous greens.  It appears to have been developed commercially.  These four replicated plots were planted at University of Florida - Fort Lauderdale in May 1994.  Throughout most of their evaluation they were mowed at 1/8 inch.  Plots were aerified the week of 21 June 1999 and were treated with excess rates of herbicides 29 June 1999 and again 7July 1999, thus the cumulative rates were actually 2X, 4X, 6X, 8X, and 10X.  Mowing was suspended as soon as treatments began.

Overall PF-11 bermudagrass performed:  Excellent (8.7)

This is the best performing of the Ultradwarf bermudagrasses in this trial.
