Rice genotype (cv. Swarna Sub1) was compared with cv. Swarna with respect to salinity stress. The modality of sub1A traits, which is primarily linked to submergence tolerance, was monitored as to its sensitivity to salinity. Proline and electrolyte leakage were not significantly changed in cv. Swarna Sub1 as compared to cv. Swarna. However, the effects of silver ions through individual, hydroponics and pre-treatment distinctly varied between two cultivars. Silver absorption distinctly varied with 45.01-fold rises in cv. Swarna against control, whereas for sodium cv. Swarna Sub1 scored the highest accumulation by 3.03-fold. Potassium depletion in plants recorded a significant down-regulation for both the genotypes, maximally under salinity by 43.78 and 22.33%, respectively. Plants exhibited a significant suppression of shoot and root length which finally manifested in dry matter accumulation by 93.95 and 89.24%, respectively, for cv. Swarna and Swarna Sub1 under pre-treatment. Chlorophyll content significantly varied among the treatments as well as between the cultivars. Carotenoids and lycopene though depleted but had not any significant variation between the cultivars. NADP(H)-oxidase was distinctly overexpressed for cv. Swarna Sub1 by 1.16-fold under salinity than cv. Swarna (1.22-fold). Still, pre-treatment with silver has maximally induced superoxide content establishing oxidative sensitivities with a peak rise of 3.07 and 2.44-fold for two genotypes. Therefore, the significant traits linked to sub1A QTL would be the selection markers or to overexpress in susceptible genotypes under the condition of salinity for better sustenance.

水稻亚1A数量性状基因座对银诱导调控的盐分响应

将水稻基因型（cv. Swarna Sub1）与 cv. Swarna Sub1 进行比较。Swarna 关于盐度压力。主要与耐淹性相关的 sub1A 性状的形态受到监测，以确定其对盐度的敏感性。脯氨酸和电解质泄漏在 cv 中没有显着变化。Swarna Sub1 与 cv 相比。斯瓦纳。然而，银离子通过个体、水培和预处理的影响在两个品种之间明显不同。银吸收明显不同，cv 增加了 45.01 倍。Swarna 反对控制，而对于钠 cv。Swarna Sub1 累积最高，达到 3.03 倍。植物中的钾耗竭记录了两种基因型的显着下调，在盐度下最大分别减少了 43.78% 和 22.33%。植物表现出对枝条和根长度的显着抑制，最终表现在干物质积累分别为 cv.93.95% 和 89.24%。预处理下的 Swarna 和 Swarna Sub1。叶绿素含量在处理之间以及栽培品种之间显着变化。类胡萝卜素和番茄红素虽然耗尽，但品种之间没有任何显着差异。NADP(H)-氧化酶对于cv明显过度表达。Swarna Sub1 在盐度下比 cv 高 1.16 倍。Swarna（1.22 倍）。尽管如此，用银预处理最大程度地诱导了超氧化物含量，建立了氧化敏感性，两种基因型的峰值升高分别为 3.07 和 2.44 倍。所以，
