Pearson’s correlation coefficients between leaf morphological and anatomical traits of Quercus brantii in semi-arid climate. Orange and yellow represent strong positive correlations. Leaf length, (LL), specific leaf area (SLA), dry matter content (DMC); stomata length (SL), stomata width (SW), stomatal density (SD), stomatal pore index (SPI), trichome length (TL), trichome width (TW) and trichome density (TD). *P < 0.05; **P < 0.01.
