| Abstract: | The content of soluble sugar,proline and betaine of two rapeseed cultivars, Yuyou 5 and Shanyou 6, after spraying on their leaves by freezing resistance inducers,were much higher than that of control group with out treatment at 4 ℃and -4 ℃.Chlorophyll fluorescence parameter F 0 of treated group was lower than that of control group. PSII photochemical efficiency (Fv/Fm) of treated group was higher than that of control group. The result showed that freezing resistance of treated group was much higher than that of control group. |
