This study was conducted to investigate the effect of vegetative rootstocks and nutrient content on some of the most important flavonoid compounds in leaf samples of Bastam genotype (BA) and Bekran (BE) cultivar and compare them with the Red Delicious cultivar flavonoids. The experiment was conducted in a factorial way of randomized complete blocks over two years. Sampling of three-year-old trees grafted on M9 and B9 rootstocks and Bekran genotype colony rootstock was done and then the amounts of nutrients including nitrogen, phosphorus, potassium and calcium and some of the most important flavonoids including Quercetin, Kaempferol, Rutin and Luteolin in Leaf samples were measured using high performance liquid chromatography (HPLC). The results of this study showed that during two consecutive years, the amount of flavonoid compounds Quercetin, Quercetin 3-ramenoside, Luteolin, and Kaemferol were affected by rootstock and scion and their interaction. Step-by-step regression analysis showed that the amount of each element had a significant specific effect on the biosynthesis of flavonoid compounds. The total amount of flavonoid compounds in leaf samples of cultivars and genotypes grafted on M9 and Bekran colonies rootstocks increased in the second year. Also, with increasing plant age and root development, increased. The total amount of flavonoid compounds in leaf samples of cultivars and genotypes. The results of this research showed that the inherent differences between cultivars determine the amount of synthesis of secondary metabolites, but the amount of these compounds can be increased by using rootstocks that have obvious differences in vigor or are more efficient in absorbing and transporting nutrients.
