1 Aldridge is a seedling strain from Von Ormy, Texas; Seedlings are from a native population near Mobile, Alabama. Numbered selections are from Shady Grove Plantation, South Carolina, and other cultivars are from various nursery sources.
2 Final height in feet following 16 years of growth (December 1983 through December 1999).
3 Final caliper measurements in inches taken at 12 inches above soil line.
4 Final canopy width in feet determined by adding East-West width to North-South width and dividing by two [(EW + NS)/2].
5 Trees are ranked based on darkest to lightest pubescence on underside of leaf (1 = darkest brown, 10 = greenest; two trees in the study ranked equal at 7 and also at 9); and leaf size (1 = smallest, 12 = largest). Leaf color determinations based on average values of 10 leaves per tree with three trees per cultivar in each of three replications.
6 Leaf area determinations (cm2) based on average values for 10 leaves per tree with three trees per cultivar in each of three replications.
