Effects of temperature, shoot-tipping, and carbaryl on fruit set of apple trees

Acta Horticulturae (80): 207-211
Effects of temperature, shoot-tipping, and carbaryl on fruit set of apple trees
Young Golden Delicious apple trees grown in pots were exposed to different temperatures during 1- or 2- week periods between bloom and the end of June drop. Trees were placed in three growth rooms within a greenhouse at the following temperature levels: 12-13 deg , 16-17 deg , and 19-21 deg C. Selected flowers were hand-pollinated. Beehives were placed in the greenhouse to ensure good pollination of all flowers and a satisfactory initial fruit set was obtained.
