Pairwise correlation matrix of salinity stress response parameters. Upper triangle: Scatter plots with regression lines (green = positive relationships, blue = negative relationships). Diagonal: Histograms with kernel density estimates showing variable distributions. Lower triangle: Bivariate density plots with Pearson correlation coefficients (*p < 0.05, **p < 0.01, ***p < 0.001). Plant height (PH), days to flowering (DF), number of tillers (TL), number of spikes per plant (SP), grains per spike (GS), spike length (SL), fresh weight (FW), 1000-grain weight (GW), and root length (RL).
