Shoot size significantly affects rooting response of sugar maple softwood cuttings

Abstract

Three hundred softwood cuttings were collected from each of three mature sugar maple trees to test the effect of shoot size on adventitious root formation. One of the trees was a good rooter (61 percent rooted); one was a poor rooter (19 percent rooted); and the third was a non-rooter (1 percent rooted). There was an insufficient number of rooted cuttings from the third tree to permit meaningful comparisons. For the other two trees, long cuttings rooted better than short cuttings. Also, thick cuttings tended to root better than thin ones for one study tree; for the other tree, relative shoot thickness within a particular length class had no effect on rooting.
