  1. EC3.0, EC5.5 and EC7.0: soil salinity at 3.0, 5.5 and 7.0 dS m−1, respectively; 0.0, 1.0, and 2.0 min: the plasma exposure times by minute. Different letters within columns refers that there are significant variations at 0.05 level of probability. Means were separated based on Duncan’s multiple range test (P ≤ 0.05).
