| Abstract:
The effect of dormant pruning and the quality of 2-year-old bearing units (BU) on fruit set and mean fruit dry weight of ‘Packham’s Triumph’ pears was determined during the 2002/03 season. Fruit set on short BU (28 cm long) was 20 percent higher and mean fruit dry weight were 20 percent more than for long BUs (56 cm). On thick BU (14 mm basal diameter) 70 percent more fruit set than on thin BU (8 mm) and mean fruit dry weight was 20 percent more than on thick BU. | |
