| 摘 要： | 以黄瓜为对象，研究了低温胁迫下不同Cu2+、Zn2+和Mn2+浓度对其幼苗叶片叶绿素荧光参数的影响。结果表明：低温胁迫下，提高营养液Cu2+、Zn2+和Mn2+浓度能使黄瓜幼苗叶片Fv/Fm、ΦPSⅡ等叶绿素荧光参数明显增强，表明Cu2+、Zn2+和Mn2+浓度的提高能显著增强黄瓜叶片光合机构抗低温损伤的能力。

| Abstract: | The effects of different concentrations of Cu2+,Zn2+ and Mn2+ nutrient solution on chlorophyll fluorescence parameters of cucumber seedling leaves under low temperature were studied.The results showed that Fv/Fm,ΦPSⅡ of cucumber seedling leaves could been increased under low temperature when cucumber was treated by high concentrations of Cu2+,Zn2+ and Mn2+.This indicated that the photosynthetic apparatus of cucumber seedling leaves could been enhanced by increasing the concentrations of Cu2+,Zn2+ and Mn2+. |
