Abstract
This investigation was conducted during 2015 and 2016 seasons on "Anna"apple trees (Malus domestica, L.). The trees were 10 years old at the start of experiment budded on Malus rootstock and grown in sandy clay loam soil in private orchard located at El-Nubaria region, El-Bahaira Governorate. The experiment involved the following treatments:1) control (spraying with tap water), 2) 5 mg/l Sitofex (CPPU), 3) 10 mg/l CPPU, 4) 15 mg/l CPPU, 5) 25mg/l Naphthalene acetic acid (NAA), 6) 50 mg/l NAA, 7) 75 mg/l NAA, 8) 25 mg/l Benzyladenine (BA), 9) 50 mg/l BA, 10) 75 mg/l BA. All applications were applied twice at full bloom (80% flowering) and after two weeks from setting. Results revealed that 75 mg/l NAA, as well as, 75 mg/l BA treatments gave the highest values of shoot length, shoot thickness and total chlorophyll compared to all others treatments during both experimental studied. On the contrary, the control treatment has the lowest values during two seasons. Also, it was noticed applications that CPPU treatments led increased fruit set and decreased fruit drop percentages. Furthermore, data showed that, 5, 10 and 15 mg/l CPPU significantly increased yield/tree and yield weight/feddan, as compared with control. Moreover, increasing rates of foliar application at all growth regulators treatments increased acidity and vitamin C content in fruits, while, all treatments did not affect total sugars and anthocyanin contents. Also, foliar application of CPPU, NAA and BA treatments increased the starch content
