 This study examined the effects of cadmium, Cd, on apple production, focusing on the rootstock and cyan interactions. The results showed that Cd can be absorbed into the rootstock and cyan, leading to increased levels of Cd in both parts. Additionally, the rootstock and cyan interacted with each other, resulting in higher levels of Cd in the cyan than in the rootstock. These findings suggest that rootstock and cyan interactions play an important role in determining how much Cd is absorbed and how much is stored in the plant.
