Research on the Physiological-Biochemical and Protein Component Changes of Wheat under Low Temperature Stress

ZUO Fang et al(Tianjin Key Laboratory of Cyto-Genetical and Molecular Regulation,College of Chemistry and Life Science,Tianjin Normal University,Tianjin 300387)  
[Objective]The purpose was to explore the effects of indirect chilling injury on the growth of wheat seedlings and the mechanism of the influence.[Method]The water culture was used to cultivate winter wheat Jing 411,and then study the growth of the seedlings,survey the content changes of MDA and dissoluble proteins.The vertical SDS-PAGE was used to separate the proteins from the leaves and study the effect of low temperature stress on the physiological-biochemical and protein component changes.[Result]The results indicated that under the low temperature stress,the leaves were curled and wilted,the content of MDA and dissoluble proteins had significantly decreasing trendency,the number of the proteins decreased by analysis of the electrophoretogram.[Conclusion]This research will provide the theoretical basis for discussing low temperature stress mechanism.
