Effects of Brassinolide Treatment on Pepper Seedlings Physiological under Water Stress

Used the pepper seedlings as experimental material,a method of controlling water usage of plants was carried out to study drought stress of the BR,in order to improving the effects of drought resistance of pepper seedlings.The results showed that after BR and water stress at the same time dealing with the tissue water content of pepper seedlings, soluble sugar content,catalase(CAT),peroxidase(POD),proline content and chlorophyll content was higher than those without BR treatment,while the relative plasma membrane permeability and MDA content in contrast,it showed that BR can improve the drought resistance of pepper seedlings.
