| Abstract | ||
| This study was carried out on a 6-year-old Barhee date palm during 2019-2020 seasons under Bahriya oasis conditions. It was aimed to study the effect of different treatments on fruit characteristics. Different thinning styles were removing 1/3 strand length of bunch (SLB), removing 1/3 central strands of bunch (CSB), removing 1/3 of total bunches number (TB) and control (without thinning). Thinning styles were divided to three groups. The first group was sprayed with 0.25% calcium boron (CaB), the second group was sprayed with 0.2% potassium phosphite (KP) and the third group was sprayed with tap water. Spraying treatments were applied once after fruit set or at kimri stage, or at khalal stage. The results indicated that, spraying CaB and KP with thinning style CSB improved fruit physical and chemical properties. Moreover, spraying after fruit set stage improved fruit weight, length, diameter and fruit size, while spraying at Kimri stage improved fruit chemical properties. The interaction between treatments of thinning style and spraying substances and spraying stages cleared that CSB thinning style with spraying CaB at fruit set stage increased fruit weight, size, as well as total and reducing sugar in both seasons. | ||
