Enhancing apricot growth and leaf nutrient content through antioxidant and bio-regulator applications

Antioxidants and plant bio-regulators were applied at critical developmental stages, specifically the pink bud and pit hardening stages. The results of the study revealed a significant augmentation in plant growth, along with notable increases in leaf macro-and micronutrient content, attributable to the application of these substances. The gibberellic acid at 50 ppm exhibited the most pronounced effects, with elevated levels observed in plant height, trunk girth, annual shoot growth, leaf area, and the concentrations of nitrogen, potassium, iron, copper, zinc, and manganese within the leaves. Conversely, ascorbic acid at 2000 ppm application demonstrated notable increases in total leaf chlorophyll content, as well as phosphorus, calcium, and magnesium concentrations within the leaf tissue. These findings elucidate the diverse impacts of exogenous substances on apricot physiology, emphasizing their role in fortifying plant vitality and enhancing leaf mineral status. The study contributes to understanding plant physiological dynamics and offers practical insights for optimizing agronomic practices to improve vegetative status as well as the mineral uptake efficiency of apricot across varied agro-ecological contexts.
