Abstract
Almond trees were sprayed in winter with potassium nitrate (KNO3) at 2 or 4%, gibberellic acid (GA(3)) at 500 ppm, and benzyl adenine (BA) at 200 ppm alone and in different combinations. Bud burst, fruit set and branch induction were studied. Gibberellic acid (GA(3)) alone or in combination with potassium nitrate (KNO3) at 2 or 4%, and benzyl adenine (BA) combined with gibberellic acid (GA(3)) and potassium nitrate (KNO3) at 2 or 4% induced earlier bud burst and increased the percentage of both vegetative bud burst, floral bud burst, fruit set and branch induction. Both potassium nitrate at (2 or 4%) and Benzyl adenine alone and their combinations had no effect in advancing burst of either vegetative or floral buds. Vegetative buds opened approximately two weeks earlier than floral buds; however, the floral buds opened approximately four weeks earlier than untreated control trees.
