Flavonoids regulate rhizosphere microbial communities and enhance salt tolerance in apples

The apple (Malus domestica) is a deciduous tree that is taxonomically classified in the genus Ap-ple in the family Rosaceae. In China, apple cultivation has a long history and has become one of the important cash crops. The fruit is favored by consumers for its unique flavor and rich nutrition, and it also occupies an important position in the agricultural economy. Salt stress is a common abiotic stress in apple planting, which seriously affects its growth and economic benefits. Therefore, it is of great significance to study the salt resistance mechanism of apple to improve its planting efficiency and adaptability.

苹果（Malus domestica）为落叶乔木，分类学上隶属于蔷薇科（Rosaceae）苹果属。在我国，苹果栽培历史悠久，现已成为重要的经济作物之一。其果实因风味独特、营养丰富深受消费者青睐，在农业经济中亦占据重要地位。盐胁迫是苹果种植中常见的非生物胁迫，会严重影响其生长与经济效益。因此，研究苹果的抗盐机制，对提升其种植效率与适应性具有重要意义。
