Fig. 4

Histogram visualization illustrates the frequency distribution of various biochemical and 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 analyzed include (A) total soluble protein (TSP), (B) total soluble sugars (TSS), (C) total free amino acids (TFA), (D) proline (Pro) content, (E) relative water content (RWC), and (F) excised leaf water loss (ELWL). Overlaid smooth lines represent kernel density estimations (KDE), providing a clear visualization of the probability distribution of each trait under the different treatments, highlighting variations and central tendencies across the genotypes.
