Physicochemical characteristics of local germplasm of fig

Turkey dominates world fig production for a long time and most parts of the country have fig production raised from seeds.
The eastern black sea region has also diverse fig germplasm obtained from seeds.
In the study 12 seed propagated fig genotypes with various fruit skin color (purple, black and green) were evaluated in terms of fruit skin color, total phenolics, soluble solids content, titratable acidity and total antioxidant capacity.
The well-known Turkish black fig cultivar ‘Bursa Siyahı’ was also included in the study.
FRAP (ferric reducing antioxidant power) assay was used to determine total antioxidant capacity of fresh fig fruit samples.
The results showed that fruit skin color of seed propagated fig genotypes was found to be very diverse, i.e., light green, light purple, purple, dark purple and black.
Total phenolics, soluble solids content (SSC) and titratable acidity greatly varied among genotypes which were in the range from 33 to 256 mg of gallic acid equivalent 100 g^‑1 fresh weight, 17.40 to 25.30% and 0.23 to 0.44%, respectively.
The local fig genotypes showed higher FRAP values compared with the cultivar ‘Bursa Siyahı’. The results suggested that genotype is the main factor that determines difference in the composition of bioactive compounds in figs and provides information on putative health benefits locally grown genotypes.
