Comprehensive Evaluation of Salt Tolerance and Germplasm Screening of Triticale Based on Principal Component Analysis-Membership Function Method
摘要
Abstract
In this study,nine triticale varieties were exposed to four salt types(NaCl,KCl,Na2CO3,and K2CO3)at five concentrations(0‰,3‰,6‰,9‰,and 12‰).Germination rate,germination energy,simple vigor index,seedling length,and root length were measured,and a comprehensive evaluation was performed using principal component analysis(PCA)combined with the membership function method.The results showed that based on the comprehensive evaluation value(D-value)obtained by PCA and member-ship function analysis,'Gannong No.2'and'Gannong No.8'were tolerant to NaCl,'Gannong No.2','Gannong No.7',and'Gannong No.9'were tolerant to KCl,'Gannong No.2'and'Gannong No.9'were highly tolerant to Na2CO3,and'Gannong No.2','Gannong No.4','Gannong No.8',and'Zangsi No.1'were tolerant to K2CO3.In conclusion,'Gannong No.2'demonstrated good tolerance to all four salt types.'Gannong No.9'showed good tolerance to KCl and Na2CO3,while'Gannong No.8'showed good tolerance to NaCl and K2CO3.These accessions can serve as candidate resources for future salt-tolerance breeding.关键词
