摘　　要：本研究通过人工低温胁迫处理研究不同低温下10个杏树品种的抗寒性,旨在选出抗寒性较强的品种,为人工选育杏树抗寒品种提供理论依据。本研究在人工低温胁迫处理后测定杏树枝条的相对电导率、可溶性蛋白含量、超氧化物歧化酶活性、过氧化物酶活性和丙二醛含量的动态变化规律,采用隶属函数分析法综合评价品种间的抗寒性差异。结果表明,可溶性蛋白含量、超氧化物歧化酶活性、过氧化物酶活性在低温胁迫下的变化趋势大致相同,随着温度的下降多数呈先上升后下降的变化趋势,但其峰期各不相同;相对电导率和部分温度范围的丙二醛含量随着温度的下降而升高,与植物的抗寒性呈负相关。通过隶属函数综合分析得出杏树的抗寒能力强弱顺序为胭脂红>崂山红>串枝红>金太阳>丰园红>兰州大接杏>陕西大黄杏>白杏>丰园29>金杏。This study investigated the cold resistance of ten kinds of apricot trees at different low temperatures by artificial low temperature stress treatment,aiming to select the varieties with strong cold resistance,and provide theoretical basis for artificial selection of cold resistant apricot varieties.In this study,the dynamic variation rule of relative conductivity,soluble protein content,superoxide dismutase activity,peroxidase activity and malonaldehyde content of branches of ten different varieties of apricots were measured after artificial low temperature stress treatment.Membership function analysis was used to comprehensively evaluate the differences in cold resistance among varieties.The results showed that soluble protein content,superoxide dismutase activity and peroxidase activity showed the same change trend under low temperature stress,which increased first and then decreased with the decrease of temperature,but their peak periods were different.The relative conductivity and malonaldehyde contents within partial temperature range increased with the decrease of temperature,and were negatively correlated with the cold resistance of plants.According to the comprehensive analysis of membership function,the order of cold resistance of apricot was Carmine Red>Laoshan Red>Chuanzhi Red>Jintaiyang>Fengyuan Red>Lanzhou Dajie Apricot>Shaanxi Big Yellow Apricot>White Apricot>Fengyuan 29>Jinxing.
