Resveratrol enhances the tolerance of <i>Malus hupehensis</i> to potassium deficiency stress.

ABSTRACT: Potassium (K) deficiency in plants can lead to metabolic disorders and growth retardation. Currently, nearly 50% of the arable land in China is experiencing a K resource deficit, significantly hindering the development of the apple industry. Resveratrol (Res), a phytoalexin, has been extensively reported to enhance plant resistance against various abiotic stresses. However, there have been no reports on the response of Res to K⁺ deficiency stress in apples. This study aims to investigate the effect of exogenous Res on the K⁺ deficiency tolerance of Malus hupehensis. The results demonstrated that applying 50 μM of exogenous Res could enhance the tolerance of M. hupehensis to K⁺ deficiency stress. Compared to non-Res treatments, external applica
