Aims Patterns of leaf trait variation and correlation have long been a key aspect in unraveling plant responses to climate change.However, the specifics how these patterns structural traits photosynthetic physiological characteristics align differ across growth types broadleaf plants remain unclear.Methods This study focused on 18 dominant or common species mixed broadleaf-Korean pine (Pinus koraiensis) forest.We measured four (leaf area (LA), thickness (LT), dry matter content (LDMC) mass per (LMA)) chlorophyll value (SPAD), intercellular CO 2 concentration (C i ), stomatal conductance (G s ) net rate (P n )).We analyzed correlations between different plants.Important findings Leaf functional displayed ranges spanning from 7.73% 74.54%.Interspecific differences accounted for majority variability LA LT, while type primarily drove C , SPAD, LDMC, LMA.G P originate mainly intraspecific differences.There were significant among all traits.Specifically, herbs showed significantly higher LA, compared shrubs trees, trees exhibited elevated LMA, G herbs.There isometric relationships
