Iran is a very rich country in fruit tree resources, and in terms of growing fruit trees in cold, subtropical, and tropical areas, Iran is one of the few places in the world that can cultivate most of the world's fruits. this study aims to investigate the flower and fruiting dynamics of some pome and stone fruit trees, including European pear (Espadona cultivar), two apple cultivars (Granny Smith and Starking), quince (Isfahan cultivar), two cultivars of nectarine (Shams and Moghan), sweet cherry (Takdaneh cultivar of Mashhad), peach (Alberta cultivar) and plum (California cultivar), in the Khorramdareh city of Zanjan province. The results obtained in the present study showed that all the studied species were able to grow and bear fruit in these areas, and can produce high-quality fruits (in terms of firmness, soluble solids, etc.). European Espadona pear cultivars were also able to produce high-quality fruits in this area of Khorramdareh city. The studied apple cultivars were also able to produce high-quality fruits in terms of morphological and physiological traits, Isfahan quince trees had better quality and yield in terms of fruit production than other stone fruits such as cherries, peaches, nectarines, and plums, However, the products of other stone fruit trees had good quality in terms of morphological and physiological traits. According to the data obtained from the flowering dynamics of different species, the present study evaluates the possibility of spring frosts.
