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, TifEagle was selected in 1990 as a dense off-type
within a plot of a Cobalt 60 gamma-irradiated Tifway 2 clone. The developer is Dr.
Wayne Hanna. These four replicated plots were planted at University of Florida -
Fort Lauderdale in May 1997. (See also the results from the 1993 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.
