Fruit Set as Related to Girdling, Early Cluster Thinning and Pruning of ‘Anjou’ and ‘Comice’ Pear1
in HortScienceAbstract
Tests with pear on P. communis L. and ‘E. M. Quince C’ (Cydonia oblonga Mill.) rootstocks showed that early fruit thinning to 1 fruit per cluster increased ultimate % fruit set of ‘Comice’; thinning to 2 fruits per cluster did not increase ultimate set Limb girdling 3 weeks after bloom did not effectively increase set, but when used in combination with cluster thinning, increased ‘Anjou’ set beyond either treatment alone. Heading-back pruning of ‘Comice’ on ‘Quince C’ in a high density plot increased both fruit set and ultimate yield relative to thinning-out pruning.
