Abstract
Abstract Cytokinin (6-BA) was applied to the dormant shoots of young apple ( Malus domestica Borkh.) and peach [ Prunus persica (L.) Batsch.] trees after applying all combinations of shoot and root chilling during rest. After greenhouse forcing, bud-break, new shoot dry weight, and new root growth were greatest in apple trees with both shoot and root chilling. In contrast, only shoot chilling was necessary for maximum response in peach. Applied 6-BA substituted for root chilling in apple trees that had only the shoot chilled, resulting in budbreak equal to trees that had both the shoot and root chilled. Applied 6-BA had no significant effect on peach budbreak or new shoot and root growth. Chemical name used: 6-benzyladenine (6-BA).
