The contribution of nanoparticles (NPs) in physiology of the plants became the new area of interest for the physiologists; as it is very much cost effective compared to the phytohormones. Our present investigation was also based on this interest in which the same doses (50 mg/L) of four different NPs were sprayed on stressed and non-stressed foliage. The experiment was conducted to assess the impact of four NPs viz., zinc oxide (ZnO), silicon dioxide (SiO₂), titanium dioxide (TiO₂), and ferric oxide (Fe₂O₃) on the morphology and physiology of linseed in the presence of sodium chloride (NaCl). Plants responded positively to all the treated NPs and improved the growth, carbon and nutrient assimilation, while salt stress increased the content of proline, hydrogen peroxide and superoxide anion. Application of NPs over the stressed plants further increased the antioxidant enzymatic system and other physiochemical reactions. Results indicate that application of NPs increased the growth and physiology of the plant and also increased the salt tolerance capacity of the plant.

纳米颗粒（NPs）在植物生理学中的贡献成为生理学家关注的新领域。因为与植物激素相比，它具有很高的成本效益。我们目前的研究也是基于这种兴趣，在相同压力下（40 mg / L）将四种不同的NPs喷洒在有应力和无应力的叶子上。进行实验以评估四种NP的影响，即氧化锌（ZnO），二氧化硅（SiO ₂），二氧化钛（TiO ₂）和三氧化_二铁（Fe ₂ O ₃）在氯化钠（NaCl）存在下亚麻籽的形态和生理 植物对所有处理的NPs均反应良好，并改善了生长，碳和养分吸收，而盐胁迫增加了脯氨酸，过氧化氢和超氧阴离子的含量。在胁迫植物上施用NP进一步增加了抗氧化酶系统和其他生理化学反应。结果表明，NP的施用增加了植物的生长和生理，并且还增加了植物的耐盐能力。
