Abstract
SummaryThe effects of GA3, GA4, GA7, and GA4+7 on apple fruit russeting were studied on the cvs Karmijn de Sonnaville and Golden Delicious. Four sprays of 10 ppm a.i. applied at 10-day intervals from the end of flowering were compared. Fruit russeting was reduced by all gibberellins in Karmijn and by all but one (GA3) in Golden Delicious. GA4 appeared slightly more effective than GA7, and in Karmijn GA7 was better than GA3. Differences between GA4 and GA4+7 were small. Fruit number per tree was generally not affected by the treatments, and only in one trial was a slight thinning effect observed. Fruit growth was slightly stimulated by some treatments, and flower-bud formation was affected negatively by the gibberellin treatments in two of the four trials. Results pertaining to fruit russeting, fruit bearing, fruit growth and flower-bud formation are briefly discussed.
