Fig. 6From: Comprehensive evaluation of physiological traits under nitrogen stress and participation of linolenic acid in nitrogen-deficiency response in wheat seedlingsPrinciple component analysis (PCA) plot of 21 variables (the same variables used in Fig. 4) in 24 wheat cultivars. All the data are based on the ratio of N deficient to N sufficient treatments. SDW, shoot dry weight; R/S, root to shoot ratio; RL, root length; EC, electrical conductivity; Chl, chlorophyll content; H2O2, hydrogen peroxide content; MDA, malondialdehyde content; Sucrose, soluble sugar content; Starch, starch content; TNC, total non-structural carbohydrates; C/N, carbon to nitrogen ratio; N, leaf total nitrogen content; 16:0, palmitic acid; 16:1, hexadecylenic acid; 16:2, hexadecadienoic acid; 16:3, hexadecatrienoic acid; 18:0, stearic acid; 18:1, oleic acid; 18:2, linoleic acid; 18:3, linolenic acid; DBI, double bond indexBack to article page
