Fig. 3: Spatial variation of different-sized stomata in Stage C cacao leaves.
From: Spatial patterning of chloroplasts and stomata in developing cacao leaves

a–c Heatmaps illustrating the spatial variation of different stomatal area size categories (quantified based on the average stomatal area size, including guard cells) across interveinal leaf segments and the four-leaf groups (G1–G4) from top to bottom. Dark green segments represent areas with the largest stomata compared to others. d Combined data from all leaves. Capital letters (A, B, C) denote significant differences in stomatal area size frequency between combined leaf segments (Tukey’s HSD test, p < 0.0001). Scale bars = 1 cm. Sample sizes: a 3048, b 5756, c 3005, d 11,809.
