Promotion and management of pear fruiting

摘要

Different pear cultivars have unique challenges associated with their fruiting habits; young d'Anjou trees can bloom profusely but set relatively few fruit, while Bartlett trees are fairly precocious and productive. Mature d'Anjou trees typically produce large fruit, despite the crop being unthinned. Bartletts require thinning to size fruit to commercial standards. Cornice is a conspicuously shy bearer. To improve production efficiencies of d'Anjou and Cornice, bloom and postbloom applications of theplant growth regulator ReTain (ammoemoxyvinylglycine) were tested to promote fruit set. For Bartlett, we have recently explored a new chemical minning agent.
