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.

Abstract
To determine the effects of pre-harvest salicylic acid (SA) treatments on postharvest life and quality of apricot fruits, four different concentrations (one, 1.5, three and 4.5 mM) were applied six days before harvesting of apricot fruits cv. ‘Shamlou’. Fruits harvested at commercial maturity ...

To determine the effects of pre-harvest salicylic acid (SA) treatments on postharvest life and quality of apricot fruits, four different concentrations (one, 1.5, three and 4.5 mM) were applied six days before harvesting of apricot fruits cv. ‘Shamlou’. Fruits harvested at commercial maturity stage and stored at 2ºC with 90 percent RH on the same day for a period of three weeks. The fruit was evaluated for weight loss, flesh firmness, total soluble solid (TSS) contents, titratable acidity (TA), ascorbic acid contents, total phenolic contents and total flavonoids in treated and nontreated fruits. Results showed that salicylic acid treatments significantly exhibited weight loss and flesh firmness compared with control. At the end of storage, the highest ascorbic acid content and total phenolic content was observed in 4.5 mM SA treated fruits. The highest flesh firmness, titratable acidity and flavonoids were observed at three mM SA treated fruits and at the end stage of storage. The lowest weight loss, TSS and pH were recorded at 3mM SA treated fruits.
