The effect of Spraying schedules and spraying with growth regulators on some field and fruit characteristics of Qaisi Apricot trees grown in Karbala Governorate
Abstract
The study was conducted in a private orchard in Karbala Governorate - Al-Husseiniyah during the growing season 2024. The research studied two factors: the first factor was the spraying schedules (at the full flowering stage, after the fruit-setting stage, and before the fruit-ripening stage), and the second factor was plant growth regulators (0, GA₃ 25 mg/L, and NAA 25 mg/L). Four characteristics were studied: the percentage of fruit drop, the percentage of soluble solids, the percentage of total acidity, and the fruit flesh thickness rate. After collecting and statistically analyzing the field data, it was found that both factors had a significant effect. The spraying schedules at the ripening stage exceeded all the characteristics under investigation, as they gave the lowest percentage of fruit drop, the highest percentage of soluble solids, the lowest percentage of total acidity, and the highest fleshy thickness of the fruit. (6.57%, 5.30%, 0.62%, and 2.24 cm) The growth regulator NAA also excelled in all other aspects.
