Effect of high salinity on rice seedlings. (A–C). Baldo and Vialone Nano plants in control and stress conditions. Seedlings were grown to the 2nd leaf stage (V2 stage) and then treated with 100 mM NaCl for 7 days. (D) Color of the 2nd leaf of Baldo and Vialone Nano in control and treated conditions recorded in the CIELab color space and converted to the red–blue–green scale. CIELAB expresses leaf color as three components: L component represents the perceptual lightness; A negative value was for green light component; A positive value was for red light component; B negative value was for blue light component; B positive value was for yellow light component. CIELab color values of the 2nd leaf were reported. The reported values are the means of four independent experiments ± standard deviation. Statistical significance was determined by one-way ANOVA followed by a Tukey test (p < 0.05). Different letters indicate significant difference. The statistical analysis was performed by comparing the values obtained for each light component (L/A/B) in leaves derived from NaCl plants over treatment time.
