Screening and comprehensive evaluation of salt tolerance in maize seedling stage
Through the comprehensive evaluation of the salt tolerance of 37 maize seedling traits,the materials with strong salt tolerance were screened,which provided germplasm resources and theoretical basis for subsequent field research.Thirty-seven maize inbred lines were treated with specific concentrations of NaCl solution,and maize traits were determined,and the test materials were comprehensively evaluated and screened by principal component analysis and membership function method,and cluster analysis.The results showed that the four indexes of seedling dry weight,seedling fresh weight,root fresh weight and root dry weight were the most closely related to the salt tolerance of maize varieties,which could be used as the main indicators for the selection of salt tolerance of maize varieties.
