[目的]评价4个樱桃主栽品种在不同低温胁迫下的抗寒特性。[方法]以早大果、红灯、拉宾斯、喀什壶汗4个樱桃主栽品种为实验材料，研究了其休眠枝在不同低温胁迫下的相对电导率（REC），脯氨酸（PRO）含量，丙二醛（MDA）含量，超氧化物歧化酶（SOD）活性和过氧化物酶（POD）活性的变化。[结果]①4个樱桃品种相对电导率大小顺序为喀什壶汗>红灯>早大果>拉宾斯，丙二醛含量的大小顺序为喀什壶汗>早大果>红灯>拉宾斯，均随着处理温度的降低呈上升趋势。②4个樱桃品种脯氨酸含量、过氧化物酶活性和超氧化物歧化酶活性的变化与其相对电导率和丙二醛含量的变化相反，大小顺序均为拉宾斯>红灯>早大果>喀什壶汗，随着低温胁迫的加剧均呈现先上升后下降的趋势。[结论]4个樱桃品种的抗寒性由强到弱的顺序为拉宾斯>红灯>早大果>喀什壶汗。

Objective] The present study was conducted to evaluate the cold resis-tance of four cherry cultivars under different chil ing stresses. [Method] Four cultivars of Cerasus, Early-mahapphala, Red light, Lapins and Kashgar Kukan were selected as the experimental materials, and the changes of the relative electric conductivity (REC), proline (PRO) content, malondialdehyde (MDA) content, superoxide dismu-tase (SOD) activity and peroxidase (POD) activity of dormant branches of the four cherry cultivars under low temperature stress were investigated. [Result] The REC of the four cherry cultivars was Kashgar kukan > Red light > Early-mahapphala >Lapins, while the MDA content was Kashgar kukan > Early-mahapphala > Red light >Lapins, both showed a rising trend in the four cultivars with the aggravating of the low temperature stress. The PRO content, POD and SOD activities of al cultivars were precisely contrary to their REC and MDA content, as al of them exhibited a sequence as Lapins > Red light > Early-mahapphala > Kashgar kukan in al culti-vars, and got a trend of first rising and then declining. [Conclusion] Therefore, our final evaluation of cold resistance of the four cherry cultivars was Lapins > Red light > Early-mahapphala > Kashgar kukan.
