Abstract:

In-depth research on the response mechanisms and defense strategies of Malus plants to salt stress is of great theoretical significance for the development of salt tolerant cultivation techniques for apples and the breeding of salt tolerant varieties. This review comprehensively analyzed the advanced results on the effects of salt stress in Malus plants,the identification,evaluation and screening of Malus plants under salt stress,the physiological processes and molecular mechanisms of salt tolerance,and the identification of salt-tolerant functional genes,aiming to obtain a comprehensive understanding of salt tolerance in Malus plants and identify the current situation and existing problems in the research,and propose the main research directions. It will provide selection and reference for the practical application of salt-tolerant Malus and the selection and breeding of salt-tolerant apple rootstocks.

Key words: Malus, salt stress, salt-tolerant mechanism
