Abstract

The phytochemical influence of rootstocks on the Hacıhaliloğlu apricot cultivar was examined in this study. Myrobolan 29-C, Myrobolan GF-31, Marianna 2624, Pixy, and Tokaloğlu rootstocks were used and organic acid, sugars, vitamin C, total antioxidant capacity, and phenolic compounds were identified. The highest phenolic compounds and antioxidant capacity were observed in Tokaloğlu rootstock. While Myrobolan GF-31 stood out in terms of organic acids and vitamin C, Pixy stood out in terms of sugar. The highest sugar content (sucrose) was recorded as 24.178 mg 100 g-1 in 'Pixy'. It was determined that Tokaloğlu rootstock had increased organic acid (1030.730 mg 100 g-1 malic acid), phenolic compounds (219.440 mg 100 g-1 chlorogenic acid), and antioxidant capacity (13.887 mg Trolox equivalent 100 g-1). Negative correlation was observed between malic acid and both glucose and sucrose. However, positive correlation was identified between catechin, chlorogenic, ferulic, and p-coumaric acid. Similarly, a linear correlation was identified between fumaric acid and antioxidant capacity. It was concluded that it would be more appropriate to use the Pixy and Tokaloğlu rootstocks in dry apricot cultivars and to use Myrobolan GF-31 and Tokaloğlu rootstocks in fresh apricot cultivars.
