ABSTRACT: As the leading global producer of apples, China’s apple industry faces substantial challenges posed by abiotic stresses. Consequently, it is imperative to carry out an in-depth synthesis and refinement of the unique physiological and molecular mechanisms underlying apple stress resistance, as well as to comprehensively and precisely uncover their response patterns under diverse abiotic stress conditions. Such endeavors are crucial for fostering the sustainable development of the apple industry. Presently, research on abiotic stresses in Chinese apples is intricately linked to industrial issues prevalent in major apple-producing regions, with a primary emphasis on improving drought, cold, and salt-alkali tolerance. This review synthesizes studies on Chinese apples, spanning tree growth, physiological biochemistry, and molecular regulation. Key questions and future directions are outlined to inform research on stress resistance and precision breeding strategies.
