Heat map of correlation among plant functional traits. Ψpd: predawn leaf water potential, Ψmd: midday leaf water potential, TLP: leaf turgor loss point, P50: leaf water potential at 50% loss of hydraulic conductance, Kleaf: leaf hydraulic conductivity, PT: palisade mesophyll thickness, ST: spongy mesophyll thickness, LA: leaf area, LDW: leaf dry weight, LT: leaf thickness, SLA: specific leaf area, SD: stomatal density, SL: stomatal length, Fv/Fm: maximum photochemical quantum yield of photosystem II. Numbers represent Pearson correlation coefficients and only the colored circles are significant correlations at P-level < 0.05 (red: positive significant correlation; blue: negative significant correlation; blank: not-significant)
