Overview

Experimental trial demonstrates enhanced sugar and antioxidant levels under deficit irrigation in 'Mirlo Rojo' apricots, indicating water savings do not compromise fruit quality.

Key Points

  • To evaluate the effects of regulated deficit irrigation on the fruit quality, antioxidant capacity, fatty acid profile, and volatile compound composition of 'Mirlo Rojo' apricots.
  • Assessed 'Mirlo Rojo' apricot (Prunus armeniaca L.) trees subjected to four irrigation regimes based on crop evapotranspiration: 100% ETc, 60% ETc, 33% ETc, and 0% ETc.
  • Administered irrigation treatments during the final fruit growth stages in May 2023 in Murcia, Spain.
  • Deficit irrigation treatments produced no adverse effects on any of the evaluated fruit quality parameters compared to full irrigation.
  • Regulated deficit irrigation increased total soluble solids, glucose, and fructose concentrations, resulting in improved maturity and sweetness indices.
  • Water restriction enhanced total phenolic content and overall antioxidant activity across the evaluated deficit treatments.
