Fig. 4

The effect of salinity stress and SA pretreatment on fresh root weight. This figure shows the impact of different salinity levels (0, 100, and 200 mM NaCl) and salicylic acid (SA) treatments (0, 0.5, and 1 mM) on the fresh root weight of various plant cultivars and genotypes. Genotype 284 showed the highest increase in fresh root weight with 1 mM SA pretreatment, while genotypes 167 and 250 showed the lowest. Mean comparisons are indicated by letters using Duncan’s test
