Salt Tolerance Potential in Onion: Confirmation through Physiological and Biochemical Traits.

Effects of Salinity on Selected Onion Accessions The combined ANOVA of fourteen accessions characterized under normal and salt stress environments showed highly significant differences ( p ≤ 0.01) for physiological parameters (SPAD, RWC, MSI, Pn, E and gS), biochemical parameters (Proline, H 2 O 2 , MDA, CAT, APX, SOD and POX), growth and bulb parameters (PH, NL, BD, BYP and TSS), and ionic concentrations (root Na + /K + , shoot Na + /K + and bulb Na + /K + ) ( Table 3 ).
