SL: salinity level, AC: accession, PH: plant height (cm), NL: number of leaf, RL: root length (cm), TDW: total dry weight (g), proline (μmol/g FW), TCE: total crude extract (g), AG: andrographolide (μg/g dry weight), NAG: neoandrographolide (μg/g dry weight), and DDAG: 14-deoxy-11,12-didehydroandrographolide (μg/g dry weight). Statistical significance is indicated by **(𝑃≤0.01), *(𝑃≤0.05), and ns (no significant).
