Abstract: Bud grafts, up to three series over 3 years, were made on seedling and tree rootstocks using scions from juvenile and mature northern red oak (Quercus rubra L.). Serial grafts on juvenile rootstock used buds collected from shoots developed from grafted scions of prior years. Rooting trials were performed in years 2 and 3 with shoot cuttings developed in situ on seedlings and trees and developed from successful grafts. Without grafting, cuttings from seedlings rooted more frequently and had more roots than cuttings from trees. Significant variation within maturation groups due to genotype and ontogeny obscured absolute between-group differences. Grafting scions of ...
