A comparison was made between the lipids of the roots of 5 grape rootstocks which differ markedly in the extent to which they permit chloride accumulation in leaves. Monogalactose diglyceride concentration was directly related to chloride accumulation in the leaves of the 5 rootstocks. Phosphatidylcholine and phosphatidylethanolamine were inversely related to chloride accumulation. The variety with the highest chloride accumulation contained an unusually small amount of sterols. A striking negative correlation between content of lignoceric acid and chloride accumulation was observed. The lignoceric acid concentration ranged from 11.9% in the rootstock with the lowest chloride accumulation to 0.8% in the rootstock with the highest chloride accumulation. This fatty acid was found mainly in the phosphatidylcholine and the phosphatidylethanolamine lipid fractions.
对 5 种葡萄砧木根部的脂质进行了比较，这 5 种砧木根部在允许叶片氯离子积累的程度上有明显差异。单半乳糖二甘油酯的浓度与 5 种砧木叶片氯离子积累直接相关。磷脂酰胆碱和磷脂酰乙醇胺与氯离子积累呈负相关。氯离子积累最高的品种含有异常少量的甾醇。木质酸含量与氯离子积累之间存在显著的负相关。木质酸浓度从氯离子积累最低的砧木中的 11.9%到氯离子积累最高的砧木中的 0.8%不等。这种脂肪酸主要存在于磷脂酰胆碱和磷脂酰乙醇胺脂质中。
