Abstract

Abstract Summer pruning significantly restricted radial growth of trunks, shoot growth, and root growth of young trees of ‘Delicious’ apple ( Malus domestica Borkh.) the year of treatment. Summer pruning early in the season was most devitalizing. Application of naphthaleneacetic acid (NAA) to the pruning cut after summer pruning had inconsistent effects on dry weight accumulation, but usually reduced regrowth. Growth of summer-pruned trees was generally similar to growth of comparably dormant-pruned trees the year following treatment.
