Data presented are means ± S.E.M of three independent replications. Two-way ANOVA followed by Tukey’s test was used for analysis. Different letters denote significant differences at p < 0.05. PH – plant height; RWC – Relative water content; TC- Total chlorophyll; Fv/Fm- Fluorescence variable/ Fluorescence maximum.
