SummaryIn four apple cultivars grown on the Lincoln Canopy system it was found that proximity of buds to the root and their position on the stem were the main factors determining whether they grew into long or short shoots, spurs or remained dormant. Despite slightly delayed bursting, basal shoots became dominant over the apical shoots due to their higher growth rates, and longer period of growth for almost the entire season. Shoots arising at positions more distant from the centre of the tree had slower growth rates, shorter internodes, more flowers per unit length and grew for a limited period. The implications of these results for the management of the four cultivars on the Lincoln Canopy system are discussed. |
