Leaflet area (a), stomatal density (b), minor vein density (c), minor vein thickness (d), stomatal length (e) and stomatal number per minor vein length (SV, f) of the apical leaflet from the first to eighth leaf in node on peanut plants grown in three light conditions. Different lowercase letters in each panel indicate a significant difference in the traits of plants in the same light condition (P < 0.05). Under each light condition, SV did not significantly change with the leaf node (f).
