Aqueous solutions of putrescine or putrescine dichloride were sprayed on flowers and fruits of the self-incompatible cultivars Leccino and Pendolino. Both diamine formulas increased fruit set and yield when applied to flowers before anthesis (Pendolino) and at full bloom (Leccino), but they slightly decreased fruit fresh weight. Putrescine dichloride was more effective than putrescine base, stimulating fruit set at 5 x 10-2M compared with 5 x 10-1M of putrescine base.
