The present work was designed to evaluate the effects of two water shortage strategies on the phenolic profile and antioxidants activities of four Prunus persica L. cultivars (Flordastar, Early May crest, Rubirich and O'Henry). Over the course of two successive seasons (2016 and 2017), three different irrigation strategies were tested: full irrigation (FI: 100 % crop evapotranspiration (Etc)), sustained deficit irrigation (SDI: 50 % ETc), and cyclic deficit irrigation (CDI: irrigation at 100 % field capacity with a soil moisture of 50 % field capacity). HPLC-UV/VIS profile of phenolic compounds, enzymatic and non-enzymatic antioxidant activities were assessed in exocarp and mesocarp. The results showed that deficit irrigation improved the content of phenolic compounds and the antioxidant activities. In O'Henry, ascorbate peroxidase activity increased significantly under CDI in exocarp (249 %). In conclusion, most cultivars showed an improvement of the fruit quality under SDI, whereas O'Henry fruits gathered the highest phenolic amounts and displayed the best antioxidant activity under CDI.

Abstract

The present work was designed to evaluate the effects of two water shortage strategies on the phenolic profile and antioxidants activities of four Prunus persica L. cultivars (Flordastar, Early May crest, Rubirich and O'Henry). Over the course of two successive seasons (2016 and 2017), three different irrigation strategies were tested: full irrigation (FI: 100 % crop evapotranspiration (Etc)), sustained deficit irrigation (SDI: 50 % ETc), and cyclic deficit irrigation (CDI: irrigation at 100 % field capacity with a soil moisture of 50 % field capacity). HPLC-UV/VIS profile of phenolic compounds, enzymatic and non-enzymatic antioxidant activities were assessed in exocarp and mesocarp. The results showed that deficit irrigation improved the content of phenolic compounds and the antioxidant activities. In O'Henry, ascorbate peroxidase activity increased significantly under CDI in exocarp (249 %). In conclusion, most cultivars showed an improvement of the fruit quality under SDI, whereas O'Henry fruits gathered the highest phenolic amounts and displayed the best antioxidant activity under CDI.
