【摘要】 杏是蔷薇科最具经济价值的核果类作物之一。因其耐干旱、抗性强、易管理，常作为上山上坡、荒山绿化的先锋树种，在乡村振兴建设中的作用愈发凸显。但杏开花早，早春低温、晚霜等天气会对杏花、幼果造成一定的危害，降低坐果率，严重时造成绝产。温度已成为制约杏树产业发展的重要因子。作者对不同杏品种抗寒性、抗寒生理生化指标、花器官抗寒特性、外源激素及抗寒基因调控等方面进行系统综述，为深入杏抗寒机理研究、提升抗寒性提供参考和理论依据。更多还原

【Abstract】 Apricot(Prunus armeniaca) is one of the most economically valuable stone fruit crops in the Rosaceae family. Due to its drought resistance, strong resistance, and easy management, it is often used as a pioneer tree species for greening mountains and barren hills, and its role in rural revitalization and construction is becoming increasingly prominent. However, apricots bloom early, and weather conditions such as low temperatures in early spring and late frost can cause certain harm to apricot flowers and young fruits, reducing fruit setting and in severe cases causing crop failure. Temperature has become an important factor restricting the development of the apricot industry. This article provides a systematic review on the cold resistance, physiological and biochemical indicators, cold resistance characteristics of flower organs, exogenous hormones, and cold resistance gene regulation of different apricot varieties, providing reference and theoretical basis for in-depth research on the cold resistance mechanism of apricots and improving their cold resistance characteristics.更多还原
