Effect of Drought Stress on Contents of Proline and Soluble Protein in Flue-cured Tobacco Leaves

YUAN You-bo et al (Guizhou Tobacco Science Research Institute, Guiyang,Guizhou 550003)  
[Objective]The research aimed to study the effect of different drought stress on the contents of proline and soluble protein. [Method] The contents of proline and soluble protein of tobacco K326 under four kinds of intensity of drought stress were studied.[Result] With time of drought-stress increasing, the proline content kept increasing, which was positively correlated with the intensity of drought stress.The soluble protein content reduced after increasing first, and the lowed range was related with the intensity of drought stress.[Conclusion] Continuous drought stress had the most influential effect on the contents of proline and soluble protein, and the summer drought was inferior to it.
