Title

Stem Cuttings from Caddo Sugar Maple Trees Differ in Their Rooting Potential

Abstract

Green softwood stem cuttings were taken from nine adult sugar maples (Acer saccharum Marshall) in Stillwater, Okla., chosen for superior horticultural traits including lack of leaf tatter and scorch during drought conditions. The cuttings were treated with 2.5 g*L-1 IBA, 5 g*L-1 IBA, 2.5 g*L-1 NAA, 5 g*L-1 NAA, 2.5 g*L-1 IBA + 2.5 g*L-1 NAA, 5 g*L-1 IBA + 5 g*L-1 NAA, 0 g*L-1 IBA + 0 g*L-1 NAA (alcohol control). Cuttings were evaluated after about seven weeks for number and length of roots. Rooting response varied by tree and there were significant differences among auxin treatments. Trees with greater rooting percentages tended to have the highest number of roots per rooted cutting and the longest roots. Seventy-five percent of cuttings from Tree 1 rooted when treated with 2.5 g*L-1 IBA + 2.5 g*L-1 NAA. Eighty percent of cuttings from Tree 9 rooted when treated with 5 g*L-1 IBA. Tree 7 cuttings rooted well regardless of hormone treatment, with 48% rooting overall and 54% rooting when auxin was greater than 0 g*L-1. Cuttings from Tree 8 did not root.
