摘要： Cucumber cultivation suffers from severe yield and quality decline due to cold damage. Cucurbita ficifolia is used as a rootstock for grafting cucumber to improve resistance due to its excellent resistance. This study used Yunnan C. ficifolia as the rootstock and Jingyan Xiamei 2 cucumber as the scion, simulating common low-temperature stress of 15 degrees C, 10 degrees C, and 5 degrees C in an artificial climate chamber, to study the mechanism of cucumber-grafted seedlings responding to low temperatures in terms of growth and development, photosynthesis, osmotic regulation substances, antioxidant system, and gene expression. The results showed that the growth and development of grafted seedlings of C. ficifolia was less inhibited, the chlorophyll content was less reduced, and the content of osmoregulatory substances was significantly increased under low-temperature stress. The activity of antioxidant enzymes in grafted seedlings of C. ficifolia was significantly upregulated at low temperatures, and the expression of antioxidant enzyme genes was consistently higher in grafted seedlings of C. ficifolia. These results confirmed that C. ficifolia as a rootstock could improve the cold resistance of cucumber. Collectively, this study provides the basis for revealing the physiological and molecular mechanism of grafting seedlings to improve cucumber's low temperature tolerance.
