 The research found that apples grown on P22 rootstock had the highest content of dry matter, crude protein, fiber, easily hydrolyzable sugars, and vitamin C, while the highest mineral compound concentration was exhibited by apples from trees growing on rootstocks P22, P2, and M.9. The highest concentration of phenolic acids was determined in the peel of fruits from trees growing on P22 and M.9. Overall, the observations suggest that rootstocks with lower growth rates, P22, M.9, lead to higher nutrient accumulation in sampean fruits.
