| Abstract: |
| Applying the method of grey correlative analysis．the correlative of drought ressistance of5varieties and 5drought ressistance indexes was analyzed．the results with grey correlative degree analysis showed that：the order of correlative degree of drought ressistance and indexes of 5alfalfa was：Pro＞SOD＞POD＞RWC＞leaf water potential．Which meaned that the effection of different indexes to5alfalfa varieties drought resistance were：the Pro was biggest and than SOD、POD and were bigger the leaf water protential was the weakest． |
