| Abstract:
The yields of cultivars of the European pear (Pyrus communis) are frequently poor on young trees and inconsistent from season to season on mature trees. Yields on pear trees are influenced by the number and quality of flowers produced, by the efficiency of pollination and fruit set, by the severity of natural or induced abscission of fruitlets and by the degree and rate of cell division and expansion in the persisting fruits. These component factors, that together determine pear yields, are themselves influenced by genetic (scion, cultivar and rootstock), environmental (climate and soil) and many management (e.g. pruning, training, use of plant growth regulators) factors. Research studies on some of these factors and their direct and indirect influences on pear yields are reviewed briefly. | |
