摘　　要：【目的】明确石河子市及周边植物地区上寄生性杂草菟丝子的种类,为其科学防除、有效监控提供依据。【方法】在石河子市内及其周边不同寄主上采集菟丝子茎、花和成熟、饱满的种子,采用形态学特征观察及ITS、rbc L、trn L-F序列分析对其进行鉴定。【结果】经形态学特征观察结合ITS、rbc L、trn L-F序列分析结果将37份菟丝子样品鉴定为2个种,分别为单柱菟丝子(Cuscuta monogyna)和田野菟丝子(Cuscuta campestris)。【结论】单柱菟丝子和田野菟丝子是新疆石河子地区的主要危害种。[ Objective] In order to identify the species of Cuscuta in Shihezi area and its surroundings in the hope of providing the basis for scientific control and monitoring of Cuscuta. [ Method ] Stems, flowers and mature, plump seeds of Cuscuta were collected from different host species in Shihezi area and its surrounding and morphology characteristics and ITS, rbcL, trnL - Fgene sequences were used to identify Cuscuta. [ Result ] A total of 37 samples of Cuscuta were identified as two Cuscuta species, Cuscuta campestris and Cuscuta mo- nogyna based on the result of morphology and ITS, rbcL, trnL - Fgene sequences analysis. [ Conclusion ] The main Cuscuta species in Shihezi are Cuscuta campestris and Cuscuta monogyna.
