In the present research, the physicochemical properties of cultivars Malas-e-Saveh and Malas-e-Yousef-Khani grown in different climatic conditions including Sari, Ali-Abad and Saveh were evaluated in 2014. This experiment was conducted based on factorial arrangement in completely randomized design. The results showed that cultivar and growth region did not have any significant effect on the content of total flavonoids and antioxidant capacity; however, these factors affected density and length of fruit, fruit length/diameter ratio, pH and EC of juice, total soluble solids (TSS), number and percent of arils, diameter and length/diameter ratio of arils and diameter and the percent of seed. Dispense Malas-e-Yousef-Khani cultivar had longer seed and higher anthocyanin content, but lower juice percentage, 100 aril weight, 100 aril water weight and aril length compared to Malas-e-Saveh cultivar. Among regions, Sari and Ali-Abad regions with more humid weather conditions had fruits with maximum juice percentage, anthocyanin and vitamin C. Saveh region with semi-arid conditions also produced fruits with maximum weight and volume and minimum length/diameter ratio of seed and seed moisture percentage. Furthermore, maximum amounts of 100 aril weight, 100 seed weight, aril and seed length were found in fruits grown in Sari region. Ali-Abad region produced fruits with maximum content of total polyphenol. Overall, the findings of this research showed that different climatic conditions showed some significant effects on the quality of fruit, aril and seed and cultivars must be selected regarding to this influences.
