In this study the pomological characteristics and antioxidant compounds of 13 genotypes of ber fruit collected from the Hormozgan province were evaluated. Ber fruits harvested at commercial maturity stage and their quantitative and qualitative characteristics were studied. The results showed that there is a significant difference between ber genotypes for these traits. The highest fruit and flesh weight, fruit diameter and fruit flesh percentage was related to genotype G3. The highest fruits and seeds were belonged to genotype G11. The level of total soluble solids (TSS), titratable acidity (TA) and TSS/TA ratio were higher respectively in the G9, G3 and G10 genotypes than others. Biochemical measurement results showed that the total phenolics and flavonoids content and antioxidant capacity of fruits is the highest in the genotype G5, while the highest amount of vitamin C obtained from genotype G4. Amount of catechin and quercetin of flavonoids were maximum, respectively in the genotypes G3 and G10. Positive correlation was observed between the amount of antioxidant activity with vitamin C, total phenolics and flavonoids content of ber fruit genotypes. Overall, the results of this study demonstrated that sensory attributes in the G10 and quantitative properties and antioxidant compounds in G3 genotype were higher and ber could be cultivated as a fruit with high nutritional values in the appropriate areas.

In this study, calcium chloride (CaCl2) and two organic calcium compounds namely Calcicat and Folical were applied at four different spray programs including All-, Early-, Mid- and Late-season spray at the Abhar region in Zanjan were compared in 2012. Some qualitative characteristics of ‘Fuji’ apple fruit such as peel color and anthocyanin, internal ethylene concentration, total phenolic content and percentage of internal browning incidence were studied at harvest and during storage. The color indices namely L*، C*and h °were influenced by the calcium solution spray. Folical increased the L* index compared to control. Fruits which received calcium solutions had higher h° index and lower C* index than control. The anthocyanin content of fruit peel was influenced only by spray timing, at harvest. Late season spray resulted in less anthocyanin accumulation compared to other programs. Total phenolic content of the peel and pulp was affected by calcium compounds and spray programs in differently ways. There was not a clear trend in phenolic compounds change during storage; meanwhile, total phenolics decreased in the fruits peel and pulp. Calcium application decreased internal ethylene concentration. All calcium treatments significantly decreased the internal browning; however, it was not observed insprayed fruits by early season Folical and midseason Calcicat.
