ThST103 confers salt tolerance phenotype in seed germination in cotton. A Curve of seed germination. The seeds overexpressing ThST103 genes and CK were germinated for 8 days in the soil augmented with 0 and 250 mmol·L⁻¹ NaCl and the germination rate was recorded daily. Values are mean ± SD (10 seeds per replicate, five replicates per treatment). Different letters denote significant differences (P < 0.05) from Duncan's multiple range tests. B Ratio of seedling survival. The germinated seedlings were grown for 2 weeks prior to the recording of seedling survival ratio. Values are mean ± SD (10 plants per replicate, five replicates per treatment). Different letters denote significant differences (P < 0.05) from Duncan's multiple range tests. C Growth of germinated seeds. Bar = 4 cm
