Figure 2. ‘Nonpareil’ trees on ‘Bright’s Hybrid’ rootstock after dormant pruning in winter 2018 (2 years after planting) to produce a narrow, palmette-style tree shape. Note the distribution of scaffold branches along the main trunk of these trees initially planted as central leader trees.

Figure 4. Shoot structure within trees. Scion cultivars budded on ‘Bright’s Hybrid’ rootstock stimulated numerous relatively short axillary shoots, in addition to the normal component of medium to long shoots. This effect was consistent across all scion cultivars tested.
Figure 3. ‘Monterey’ (left) and ‘Nonpareil’ (right) trees on ‘Garnem’ rootstock in January 2020. Trees were planted in 2016. Pruning treatments were applied to groups of three trees each. The first three trees along the row are the unpruned control trees, the second set of three trees are the narrow-pruned trees planted with a central leader. The branches in the unpruned control trees can be seen drooping down with the weight of the fruit.
