Correlation analysis among plant growth parameters, nutritional composition and photosynthetic pigments under eCO2 stress and fungus gnat infestation. LW: leaf width; LT: leaf thickness; PH: plant height; SD: stem diameter; SS: soluble sugar; SP: soluble protein; FAA: free amino acid; FFA: Free fatty acid; Ch-a: Chlorophyll a; Ch-b: Chlorophyll b; Ch: Chlorophyll; Ca: carotenoid. In the heatmap, colors closer to red indicate higher correlations, while colors closer to blue represent lower correlations.
