ABSTRACT: Cold stress is one of the most important environmental factors affecting crop growth and agricultural production. Most temperate plants acquire cold tolerance by a process called cold acclimation. In this study, the annual branches of three varieties of pitayas (Fulong, Xianmi, and Zihonglong) with different cold resistance were selected. The physiological response in cold stress were investigated using a multivariate statistical method. Meanwhile, to clarify the cold resistance related proteins and pathway in annual pitaya branches, a comparative proteomic approach was also conducted. Physiological changes results showed that cold stress could decrease the moisture and chlorophyll contents, to the contrary, increase the REC, the contents of MDA, soluble protein, free proline, and soluble sugar, and enhance the activities of POD, SOD, and CAT.
