Tifdwarf bermudagrass (1993 planting)
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.

Originated from the USDA-ARS, Coastal Plains Research Station, in Tifton, Georgia, Tifton, Tifdwarf was discovered as an off-type in early plantings of 328 (Tifgreen).  It was released in 1960 by Dr. Glenn Burton, and during the last 40 years it has been the mainstay of golf greens in Florida.  These four replicated plots were planted at University of Florida - Fort Lauderdale in May/June 1993.  (See also the 1997 planting).  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.
