The present investigation was carried out during two successive seasons of 2002 and 2003 on Canino Apricot trees budded on seedlings rootstock at a private orchard located at El-Khatatba district, Menofia Governorate Egypt. Trees were sprayed at full-bloom stage with boron, GA3 and active dry yeast at different concentration alone or in their combinations. Results showed that spraying Boron, GA3 and active dry yeast either singly or in combination caused a remarked promotion in leaf min-eral status, yield and fruit quality compared with control treatment Combined appli-cation solution of 400ppm Boric acid, 40ppm GA3 and 2% active dry yeast at full bloom stage gave the best results with regard to the yield and fruit quality of Canino Apricot.
