Principal component analysis of data sets of germination percentages (G), germination index (GI), shoot (S) and root (R) lengths, drought tolerance index for shoot (SL_DTI) and root (RL_DTI) lengths under drought (15%, 20% and 30% PEG) and combined (P-15% PEG, P-20% PEG and P-30% PEG) 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 present high voltage electrical discharge (HVED) pretreatment.
