Fig. 3

Histogram visualization showing the frequency distribution of physiological traits across 40 cotton genotypes under three treatments: T1 (green) control condition (100% field capacity), T2 (orange) moderate drought stress (60% field capacity), and T3 (purple) severe drought stress (40% field capacity). The traits include (A) photosynthesis rate (Pn), (B) transpiration rate (E), (C) stomatal conductance (gs), (D) chlorophyll a (Chl.a) content, (E) chlorophyll b (Chl.b) content, and (F) total chlorophyll (T.chl) content. Overlaid smooth lines represent kernel density estimations (KDE), providing a clearer view of the probability distribution of each trait under different drought stress levels, highlighting variations and central tendencies across the genotypes.
