A Study on Biochemical Characters of Flag Leaf Drought Resistance after Anthesis on Different Wheat Varieties

doi:10.3321/j.issn:1000-7091.2006.04.011

Abstract

Abstract: Under the condition of certain water stress.17 wheat varieties were compared with different drought resistance and its content of SOD,CAT,Pro,soluble protein and soluble sugar of flag leaf after anthesis,then we analyzed the feasibility of identify index.The results indicated that three kinds of wheat have the same of trend in the above biochemical characters,the wheat varieties with stronger drought resistance was super to other kinds of wheat,three kinds of types wheat varieties have difference in anti-oxidized protection enzyme as well as seepage adjustment matters.Content of SOD at 7 days after anthesis,content of CAT and Pro after anthesis,content of soluble protein and sugar at 14 days after anthesis could do the identify index of drought resistance.

Key words: Winter wheat, Drought resistance, After anthesis, Flag leaf, Biochemical indexes
