Abstract Several chemicals, used to induce budbreak of deciduous fruit trees in areas lacking sufficient chilling units were applied to 3 cultivars of red raspberry ( Rubus idaeus L. cvs. Delmes, Mailing Exploit, and Schoenemann) grown in Bet Dagan, Israel. All treatments including oil + dinitrol-o-cresol (5%), KNO 3 (5%), thiourea (1%), and cyanamide (4%) solutions improved budbreak, and increased yield. The most impressive effect was obtained with 4% cyanamide, which increased fruit size, earliness, and yield.
