The interaction of growth regulators and tree orientation on fruit-bud formation

Acta Horticulturae (34): 185-188

The interaction of growth regulators and tree orientation on fruit-bud formation

One-year-old potted Cox's Orange Pippin apple trees were sprayed with 1800 p.p.m. daminozide either about 3 weeks after flowering or soon after shoot growth had ceased. Both treatments promoted flowering to the same extent. Flowering was more prolific on horizontal than on vertical shoots. The quality of the flower clusters was poor; many flowers and sometimes clusters dropped prematurely. Spraying with 500 p.p.m.

Alar [daminozide] or CCC [chlormequat] each at 3000, 4000 or 5000 mg/kg were applied to apple, peach and apricot trees. The treatments had no marked effect on fruit sugar, acid and vitamin C contents, but they advanced ripening by 3-4 days.
