Identification of linseed drought tolerance. a-d Z141 (left) and NY-17 (right) phenotype differences under normal water content (CK), drought stress (DS), re-watering (RW), and repeated drought (RD) respectively. e, f Z141 and NY-17 phenotypic differences between drought stress (left) and controls (right). g, h Z141 and NY-17 ALWC and RLWC with means and SEs (n = 3) respectively. The abscissa indicates ASWC, and the ordinates indicate ALWC (g) and RLWC (h). Blue dots indicate Z141, and orange dots indicate NY-17. **, p < 0.01, see Table 1 for ANOVA and Table S2 and Table S3 for a summary of these drought tolerance-related traits
