Biplot of root morphology and root hair traits of six wheat genotypes under two treatments (C, control, and T, 10% PEG). Data points indicate PC scores of each wheat genotype under each treatment: PH = plant height; TLL = total no. of live leaves; LS4 = leaf injury scores for the fourth leaf; LS5 = leaf injury scores for the fifth leaf; ChlC = chlorophyll content; SDW = shoot dry weight; RDW = root dry weight; TPr = total number of root-bearing phytomers per tiller; TNR = total number of roots per tiller; NSR = number of seminal roots; LSR = length of seminal roots; MALmax = maximum main axis length; MALPr1 = main root axis length at phytomer 1; MAD = main axis diameter; PAL = length of first-order lateral roots; PAD = diameter of first-order lateral roots; DPA = density of first-order lateral roots; SAL = length of second-order lateral roots; SAD = diameter of second-order lateral roots; DSA = density of second-order lateral roots; DRHMA = density of root hairs of main axis; DRHSA = density of root hairs of second-order lateral roots; DRHPA = density of root hairs of first-order lateral roots; RHLPA = length of root hairs of first-order lateral roots.
