This work was undertaken to determine the kinds and amount of substances that would account for the previously demonstrated differential growth of Claviceps purpurea on guttation fluids from Rosen rye, Genesee wheat, and Traill barley seedlings. Chromatographic methods were used for determining amino acids and sugars, spot tests and spectrometric methods for inorganic materials, and microbiological methods for vitamins.Total sugar content is about equal in rye and barley fluids, but lower in wheat. Glucose is the principal sugar component of the rye and barley fluids and galactose highest in wheat. Most of the amino acid in all 3 fluids is aspartic acid or asparagine. Barley fluid is far higher than the other 2 in total amino acids, with wheat the lowest. Most inorganic elements are found to be highest in barley and lowest in wheat, with the exception of iron where rye is highest and barley lowest. Barley fluid is highest in choline, p-aminobenzoic acid, thiamine, and uracil, while rye is highest in inositol and pyridoxine. Wheat is much lower than the other 2 in choline and inositol.
这项工作的目的是确定先前证明的麦角菌在罗森黑麦、杰内斯小麦和垂穗大麦幼苗的溢泌液中生长差异的物质种类和数量。本文使用色谱法测定氨基酸和糖，用斑点试验和光谱法测定无机物质，用微生物学法测定维生素。在黑麦和大麦液中总糖含量大致相等，但在小麦中较低。葡萄糖是黑麦和大麦液中主要的糖成分，而半乳糖在小麦中含量最高。在所有 3 种液体中，大多数氨基酸都是天冬氨酸或天冬酰胺。大麦液的总氨基酸含量远高于其他两种，而小麦的含量最低。除铁外，大多数无机元素在大麦中含量最高，在小麦中含量最低，而在黑麦中含量最高，在大麦中含量最低。大麦液中胆碱、对氨基苯甲酸、硫胺素和尿嘧啶含量最高，而黑麦中肌醇和吡哆醇含量最高。小麦中胆碱和肌醇的含量明显低于其他两种。
