Fig. 2From: Intraspecific differences in plant functional traits are related to urban atmospheric particulate matterPlant functional traits under the influence of different amounts of dust deposition. Figures (a)-(f) are leaf thickness, chlorophyll content index, specific leaf area, leaf dry matter content, leaf tissue density, and stomatal density. T1: outer sidewalk area (slightly polluted area of atmospheric particulate matter), T2: area between the relief road and the sidewalk (moderately polluted area of atmospheric particulate matter), T3: area in the middle of the main road (heavy pollution area of atmospheric particulate matter)Back to article page
