Abstract<\/strong><\/span><\/p>\n

The study was carried out during the years 2019 and 2020 at Blouta village of Al-Haffa city in Lattakia governorate, in apple orchard (Starking Delicious), total area of 5 dunums, on trees 20 years old and planted with (5*5) m spacing and grafted on Malus domestica<\/em> Borkh rootstock. aim of the research was to study the effect of foliar spray with boron and ascorbic acid On content of the leaves of total chlorophyll and mineral elements and the quality of the fruits of the Starking Delicious<\/em> apple variety and to determine the compound that achieves the best results. The experiment was designed in complete randomized way, and included four treatments with five replications and one tree in each replication: (T0) control: Spray only with water, (T1) Spray with boron at a concentration of\u00a0 170 ppm, (T2) Spray with ascorbic acid at a concentration of 0.5 g\/L, (T3) Spray with boron at a concentration of\u00a0 170 ppm and Spray with ascorbic acid at a concentration of 0.5 g\/L. Foliar spraying with boron at a concentration of 170 ppm and ascorbic acid at a concentration of 0.5 g\/L, alone or complex, improved the studied characteristics. The treatment of foliar spraying with boron at a concentration of 170 ppm and ascorbic acid at a concentration of 0.5 g\/L together gave the best results, as it increased the content of leaves from chlorophyll (2.60) mg\/l, nitrogen (2.09)%, phosphorous (0.22)%, potassium (0.56)%, and boron (44.9)ppm compared to the control (1.86 mg\/g, 1.15%, 0.15%, 0.43%, 19.4ppm) respectively, and it gave the largest weight and increased size of the fruit (172.9 g, 185.8 cm3<\/sup>) compared to the control (143.8 g, 155.6 cm3<\/sup>), respectively, and the percentage of total soluble solids and total sugars (16.15%, 13.51%) compared to the control (13.51%, 11.38%), respectively.<\/span><\/p>\n
