Physicochemical changes of leaf in different position and fruit in four edible fig cultivars

Fig is one of the first plants cultivated by humans that has global expansion. This study was conducted to investigate the physicochemical changes in different position of leaf (2 year cutting, Leaf next to immature syconium, Leaf next to ripe fruit, Leaf next to overripe fruit, Leaf next to fallen fruit) and fruit in four edible cultivars (Matti, Shah-Anjir, Sabz, Siah) as factorial experiment in framework of completely randomized block design in three replicates. Results indicated that leaf properties are dependent on its location. In all fig cultivars, chlorophylls of leaf next to immature syconium decreased, while as the fruits continued to grow, chlorophylls of leaf next to them increased. Two year cutting in Shah-Anjir cultivar had the highest chlorophyll a and total. Leaf next to fallen fruit position in Shah-Anjir had the greatest content of chlorophyll b. The highest carotenoid content were recorded in leaf next to fallen fruit in Siah cultivar. Sabz cultivar obtained the highest anthocyanin content in positions of the leaf next to overripe fruit and leaf next to fallen fruit as well. Two-year cutting and leaf next to immature syconium had the greatest amount of stomatal conductivity in Matti cultivar. In Shah-Anjir and Siah cultivars, the highest sugar and starch was at the position of leaf next to fallen fruit. The highest content of skin sugar, total soluble solid (TSS) and TSS/TA in Siah cultivar fruit and the highest content of sugar and starch of fruit pulp and pH were observed in Sabz cultivar fruit. Shah-Anjir cultivar obtained the greatest total acidity of fig fruit.
