| Abstract | ||||
| THE PRESENT study was conducted during 2011 and 2012 seasons …..on "Le-Conte" pear trees (Pyrus communis X Pyrus pyrifolia). Trees were 7-year-old, budded on Pyrus communis rootstock and grown on calcareous soil under flood irrigation system in a private orchard located at Borg El-Arab region, Alexandria Governorate. Thirty nine trees were chosen and planted at 5 x 5 m apart. Thirteen treatments were carried out in this study; CPPU, GA3, Milagrow and Pepton were sprayed at full bloom or at fruit set. Results showed that spraying with 10 or 15 ppm CPPU at fruit set recorded the highest values of yield and its monetary value, fruit set, fruit weight, fruit size and TSS, and the lowest values of fruit firmness and acidity. While, control and spraying with Milagrow at full bloom recorded the lowest values of yield, fruit set, fruit weight, fruit size and TSS, and the highest values of fruit firmness and acidity in both seasons. | ||||
