Pearson’s correlation matrix showing the relationships between various physiological, biochemical, and morphological traits across cotton genotypes under three treatments: (A) control, (B) moderate drought stress, and (C) severe drought stress. The color scale represents the strength of the correlation, with blue indicating positive correlations and red indicating negative interactions. Asterisks depict statistical significance levels (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001).
