摘  要:
Three varieties were employed as materials to study changes of photosynthetic traits under low-temperature stress. The results showed that Pn, Gs and Tr decreased under low-temperature treatment. Ci decreased under low-temperature treatment 18°C/9°C, and 16°C/7°C, and it decreased in earlier stage after increased under 14°C/5°C. WUE was increased in earlier stage and after stabilized. The order of the three varieties of cold resistance were Jinyu 5>Xingken 3>Jidan 198. They could make self-regulation through adjusting Gs, Tr, Ci and WUE.
