Pearson’s correlation coefficient analysis of different traits recorded under control and drought conditions at seedling stage. Values above diagonal represent control and below diagonal represent drought conditions. Colour intensity increases from Red to Blue from negative to positive correlations and values in bold show significant correlations between the traits. Seedling survival (SS), biomass (BM), total root length (TRL), total projected area (TPA), total surface area (TSA), average diameter (AVD), root volume (RV), tips number (TN), fragile root length (FRL), fragile root surface area (FRSA), fragile root volume (FRV), fragile roots tips number (FRTN), fork number (FN).
