Clustered heatmap of morphology, organic osmolytes, gas exchange and photosynthetic pigments of Cynodon dactylon and hierarchical dendrogram in response to control and drought treatments. C (control), D (drought), PH (plant height), SL (stolon length), LL (leaf length), LW (leaf width), NT (no of tillers), EL (electrolyte leakage). Chl a (chlorophyll a), Chl b, (chlorophyll b), Caro (carotenoids). Net CO2 assimilation rate (A), transpiration rate (E), stomatal conductance (gs), (WUE) water use efficiency. MDA (malondialdehyde), ROS, (reactive oxygen species), H2O2 (hydrogen peroxide), POD (peroxide dismutase) and SOD (superoxide dismutase)
