A significant abiotic stressor that negatively impacts plant seed germination and seedling establishment is soil salinization, especially in staple crops like wheat (Triticum aestivum L.). The complex ionic stressors that make up salinity include divalent salts (MgCl2), alkaline salts (NaHCO3), and neutral salts (NaCl, KCl), each of which has unique effects on osmotic and ionic toxicity. The present understanding of how various ionic salt stressors affect the dynamics of wheat germination and the early development of seedlings is summarized in this article. We talk about physiological and biochemical reactions, possible adaptive mechanisms, and the ionic specificity of toxicity. Important research findings show that: (1) germination rate and seedling vigor are reduced in response to salt content; (2) growth parameters are affected by ionic composition; and (3) genotypic variability in salt sensitivity is observed in response to salinity stress. Improving wheat performance in saline soils and developing breeding plans for salt tolerance require an understanding of these dynamics.
