Lemongrass plants were maintained under two NaCl concentrations (160 and 240 mM). These concentrations were selected as per our earlier finding on the salt sensitivity of lemongrass plants (Mukarram et al., 2022c (link)). Salt treatments began 21 days after transplantation. NaCl concentrations were supplied as 300 mL of 40 mM NaCl solutions every alternate day to attain the final concentration and to avoid osmotic shock. The control group was supplied only with 300 mL of double distilled water.
