Salinity stress is continuously declining crop production throughout the world. Various strategies are in use to mitigate its effect on crop plants. The current study was performed to resolve the effects of exogenous selenium (Se) (1 μM) on the two millet varieties viz., Panicum miliaceum L. (proso millet: PM) and Setaria italica L. (foxtail millet: FM), which were subjected to salt stress (NaCl) of varying amounts. The salt treatments (50–200 mM NaCl) decreased the tolerance index (TI) of both shoots and roots and the Se application reversed the effect. The PM shoots and FM roots showed better tolerance index ranging up to 95.42% and 101%, respectively. The salt treatments decreased the biomass, relative water content (RWC) and photosynthetic pigments (PP) in a dose-dependent manner with respect to control. The Se application showed a maximum improvement in biomass (49.09% and 293.28%), RWC (14.49% and 20.42%) and PP (228.86% and 507.22%) in PM and FM, respectively, in comparison to highest salt treatment (200 mM). The salt treatments increased the membrane damage as evidenced by electrolyte leakage (EL) and thiobarbituric acid reactive species (TBARS). However, Se application showed improvement in EL (15.62% and 49.18%) and TBARS (42.34% and 34.20%) in PM and FM, respectively, in comparison to salt treatments. When comparing the two varieties for the parameters it was found that FM performed better than PM. The Se-mediated resistance of millets (PM, FM) toward salinity makes them a model for studying stress responses at different stages of growth and development. This would help screen the resistant varieties and in future, these could be utilized for cultivation on marginal lands for sustainable growth and yield. Thus, overall the application of Se in low doses offers promising potential for use in high salinity conditions.

盐分胁迫使全世界的农作物产量持续下降。正在使用各种策略来减轻其对农作物的影响。当前的研究是为了解决外源硒（Se）（1μM）对两个小米品种Panicum miliaceum L.（proso millet：PM）和Setaria italica的影响。L.（狐尾谷子：FM），其经受不同量的盐胁迫（NaCl）。盐处理（50–200 mM NaCl）降低了芽和根的耐受指数（TI），硒的施用逆转了这种作用。PM苗和FM根表现出更好的耐受指数，分别高达95.42％和101％。相对于对照，盐处理以剂量依赖性方式降低了生物量，相对含水量（RWC）和光合色素（PP）。与最高盐处理（200 mM）相比，硒的施用显示出PM和FM的生物量（49.09％和293.28％），RWC（14.49％和20.42％）和PP（228.86％和507.22％）的最大改善。 ）。盐处理增加了膜的损坏，电解质泄漏（EL）和硫代巴比妥酸反应性物种（TBARS）证明了这一点。然而，与盐处理相比，硒施用在PM和FM中分别显示出EL（15.62％和49.18％）和TBARS（42.34％和34.20％）的改善。当比较两个品种的参数时，发现FM的性能优于PM。硒介导的小米（PM，FM）对盐分的抵抗力使它们成为研究生长和发育不同阶段的应激反应的模型。这将有助于筛选抗病品种，并在将来将其用于边缘土地上的耕种，以实现可持续增长和产量。因此，低剂量硒的总体应用为在高盐度条件下使用提供了广阔的前景。当比较两个品种的参数时，发现FM的性能优于PM。硒介导的小米（PM，FM）对盐分的抵抗力使它们成为研究生长和发育不同阶段的应激反应的模型。这将有助于筛选抗病品种，将来，这些品种可用于边际土地上的种植，以实现可持续增长和产量。因此，低剂量硒的总体应用为在高盐度条件下使用提供了广阔的前景。当比较两个品种的参数时，发现FM的性能优于PM。硒介导的小米（PM，FM）对盐分的抵抗力使它们成为研究生长和发育不同阶段的应激反应的模型。这将有助于筛选抗病品种，将来，这些品种可用于边际土地上的种植，以实现可持续增长和产量。因此，低剂量硒的总体应用为在高盐度条件下使用提供了广阔的前景。这些可用于边际土地上的耕作，以实现可持续增长和产量。因此，低剂量硒的总体应用为在高盐度条件下使用提供了广阔的前景。这些可用于边际土地上的耕作，以实现可持续增长和产量。因此，低剂量硒的总体应用为在高盐度条件下使用提供了广阔的前景。
