Figure 6

Principal component analysis of data sets of germination percentages (G), the germination index (GI), shoot (S) and root (R) lengths, and salt tolerance indices for germination (STI_G), shoot (STI_DT) and root (STI_R) lengths under salt treatments (90, 16 and 230 mM) and combined (P-90 mM, P-160 mM and P-230 mM NaCl) treatments. Genotypes Bernarda (B) and Tena (T). Factor loadings (A) and scores (B) of first two factors. Numbers beside each variable represent the day of treatment. Red marks represent high voltage electrical discharge (HVED) pretreatment.
