Effect of cold plasma pre-treatment of seeds lasting for 6, 8, and 10 min on the Na and K content of root and shoot of Prosopis koelziana plants under both control and saline stress conditions. The means were subjected to statistical analysis using Duncan’s multiple range test, and differences were considered significant at P < 0.05. Means denoted by different letters were found to represent significant differences, while those with identical letters were statistically similar. (S0 = Normal condition, S100 = salinity 100mM NaCl, S200 = salinity 200mM NaCl, Ct = non pretreated plant, P6 = pretreated of seeds with plasma for 6 min, P8 = pretreated of seeds with plasma for 8 min, P10 = pretreated of seeds with plasma for 10 min).
