Fig. 5: Spatial correlations between leaf traits, chloroplast clusters, and stomata in Stage C cacao.
From: Spatial patterning of chloroplasts and stomata in developing cacao leaves
Leaf segment area, defined by midrib and secondary veins, correlates significantly with both chloroplast cluster area (r = 0.28, p < 0.0001) and stomatal area (r = 0.23, p = 0.04), along with other size-related traits. A strong positive correlation also exists between chloroplast cluster area and stomatal area (r = 0.65, p < 0.0001). Furthermore, leaf greenness (inversely proportional to green pixel intensity) is significantly correlated with both chloroplast cluster area (r = 0.54, p < 0.0001) and stomatal area (r = 0.41, p < 0.0001). Detailed correlation values and p-values are provided in Supplementary Data 1. AS area size, P perimeter, L length, W width, LWR length-to-width ratio, Cir circularity, and Corr correlation.
