用１００ｍｍｏｌ／ＬＮａＣｌ处理大麦（ＨｏｒｄｅｕｍｖｕｌｇａｒｅＬ．）幼苗２ｄ，根系液泡膜微囊膜脂不饱和度上升，并不随外源脂肪酸的饱和度而改变。外源硬脂酸和亚油酸降低大麦幼苗对Ｎａ＋的吸收及其向地上部的运输，增加Ｋ＋的吸收和向地上部的运输，降低根系的电解质渗漏率。增加液泡膜磷脂、糖脂结合半乳糖含量及Ｈ＋ＡＴＰａｓｅ和Ｈ＋ＰＰａｓｅ（焦磷酸酶）活性，与它们调节大麦对离子的吸收、分配的结果相一致，硬脂酸和亚油酸均有一定程度的缓解盐害的效应，亚油酸的效应大于硬脂酸
Treating barley (Hordeum vulgare L.) seedlings with 100 mmol / L NaCl for 2 days resulted in an increase in unsaturation of membrane lipids in the vacuolar membrane of root system and did not change with the saturation of exogenous fatty acids. Exogenous stearic acid and linoleic acid decreased Na + uptake by barley seedlings and their uptake into shoots, increased K + uptake and translocation to shoots, and decreased electrolyte leakage rate in roots. Increased tonoplast phospholipids, glycolipids and galactose content and H + ATPase and H PPase (pyrophosphatase) activity, with their regulation of barley absorption of ions, the distribution of the results are consistent, both stearic acid and linoleic acid To a certain extent, the effect of salt damage can be alleviated. The effect of linoleic acid is greater than that of stearic acid
