Fig 1.
Physiological and biochemical characters: The SOD activity (A), MDA content (B), Proline content (C) and the RWC (D) in the leaves of the Susceptible check IR64 and the two parental genotypes (IR60080 and GIZA 178) and the candidate line under control and drought stress conditions. Values represent means ± SD. The asterisks above the bars indicate statically significant differences and different letters indicate significant differences between the lines. (P <0.001).
Fig 2.
Abaxial stomata density in the four genotypes under drought stress conditions.
Values represent means of n = 10 ± SEM (one way ANOVA).
Fig 3.
Dark adapted Fv /Fm values over drought period in the four genotypes.
One way ANOVA were performed to compare values for each day. Asterisks indicate statically significant differences p < 0.01.
