  1. Means within each parameter followed by the same letter are not significantly different at p ≤ 0.05 using Duncan’s test. Capital letters are used for the main effects.
  2. SSI salt sensitivity index, SGS shoot growth during stress, NLGS number of new leaves growth during stress, ILLS increasing the length of largest leaf during stress.
