| Abstract: | Low temperature is one of the abiotic inhibitors limiting the growth and distribution of rapeseed.Recent research was systematically reviewed on regulative response in physiology and biochemistry at low temperature,such as membrane and enzyme activity,osmotic regulation substances and their relationship with freezing resistance.Research progress in gene engineering of rapeseed cold resistance was also described.Current problems and potential solutions in cold resistance research were discussed. |
