Abstract :
An experiment was conducted to evaluate the differences between the spring and summer crops of three fig genotypes namely, Golbahar, Kamal Abad, and Rezvan 41 in Golestan province. The fruit samples were collected from two different fruit crops and some morphological and phytochemical traits were studied based on the specific descriptor and standard methods. The analysis of variance showed that there were some significant interaction between genotype and fruit type on length, width, and shape of the fruit, stalk and neck length, and pulp length, where there was observed no significant effect on the ostiole diameter. The results showed that the summer fruits were smaller than spring fruits and had lower amount of fruit length and diameter, stalk and neck length, and pulp length in most of the genotypes. Regardless of the genotype, the ostiole diameter was higher in spring fruits than summer fruits. The analysis of variance also showed that genotype and fruit type had significant interaction effects on flavonoid and anthocyanin but not on total soluble solids, titratable acidity and phenols. Summer fruits had higher amount of total soluble solids and titratable acidity but lower phenols. Kamalabad genotype also showed higher amount of total soluble solids and titratable acidity than other genotypes. In Golbahar genotype, the spring fruits had lower anthocyanin while this was lower in other genotypes. In contrast, in all genotypes under study spring fruits had higher amount of flavonoid.
