Özet

This study was conducted over three harvest years to determine effects of Turkish fg genotypes grown in the eastern Mediterranean region of Turkey on phytochemical and fruit quality characters. Fruit quality characters such as fruit weight, fruit width, fruit neck length, total soluble solids (TSS), pH, acidity, and TSS/acidity were examined. Total phenolics (TP), total anthocyanins (TA), antioxidant capacity (TAC), fructose (FRUC), glucose (GLUC), sucrose (SUC), and variables describing fruit skin and fesh colors (L*, a*, C, and ho) were also determined. Analysis of the data obtained from 12 fg genotypes, and three harvest years demonstrated a highly signifcant infuence of genotype on phytochemical and fruit quality characters. 'Bursa Siyahi{dotless}', which has dark black fruit skin, had the highest levels of TA (113.6 μg cy-3-rutinoside g1 fw), TP (105.2 mg GAE/100 g fw), and TAC (10.9 mmol Fe2+ kg-1 fw). Three yearly averages of fruit weight ranged from 22.8 g ('Sari{dotless} İncir') to 57.5 g ('Bursa Siyahi{dotless}'), and ostiole width ranged from 0.9 mm ('Bursa Siyahi{dotless}') to 3.7 mm (31-IN-16). These results indicate that TP (r = 0.77) contents correlated moderately to TAC, more so than with TA (r = 0.56). Both FRUC and SUC were negatively correlated with TA (r = -0.34 and r = -0.42, respectively). These data demonstrate that genotype is the main influence on the phytochemical and fruit quality characters of figs.
