Peach thinning is a compulsory agronomic technique in order to achieve quality fruit production, but is economically expensive. Chemical thinning of flowers may represent an important strategy, especially in southern areas of Italy where spring frosts are not a risk. The experiment was carried out on flat peach (Prunus persica var. platycarpa) ‘UFO 4’ in two areas of the Catania Plain. Ammonium thiosulfate (ATS), a liquid fertilizer that at high concentrations has a caustic effect was used at full bloom at three different concentrations. Manual thinning was executed 35 days after treatments on some replications. In order to evaluate the effectiveness of treatments, fruit set percentage, number of fruit hand thinned, diameter and average fruit weight and yield per plant were measured.

Abstract
Peach thinning is a compulsory agronomic technique in order to achieve quality fruit production, but is economically expensive. Chemical thinning of flowers may represent an important strategy, especially in southern areas of Italy where spring frosts are not a risk. The experiment was carried out on flat peach (Prunus persica var. platycarpa) ‘UFO 4’ in two areas of the Catania Plain. Ammonium thiosulfate (ATS), a liquid fertilizer that at high concentrations has a caustic effect was used at full bloom at three different concentrations. Manual thinning was executed 35 days after treatments on some replications. In order to evaluate the effectiveness of treatments, fruit set percentage, number of fruit hand thinned, diameter and average fruit weight and yield per plant were measured.File | Dimensione | Formato | |
