  1. No-salinity, moderate salinity and high salinity: soil salinity at 3.0, 5.5 and 7.0 dS m− 1, respectively; PD0, PD1 and PD2: plasma dose of 0.0, 1.0, and 2.0 min, respectively. Varied letters of columns points out that there are significant differences at 0.05 level of probability. Means were distinguished employing Duncan’s multiple range test (p ≤ 0.05).
