Evaluating Stool Layering For Producing Own-Rooted Clones of Northern Red Oak

The current study uses nursery run seedlings to evaluate several stool layering treatment protocols to determine which will be most effective in producing own-rooted clones for each species. Seedlings of both species were grown for one season at close spacing, and pruned to 5 centimeters while dormant. The cut seedlings were then subjected to 4 replications of 3 treatments, and an untreated control. The treatments involved mounding with moist sawdust at various growth stages from complete dormancy through >10 centimeters of shoot extension.
