In this study, the effects of foliar methyl jasmonate (MeJA) and riboflavin (Rbf) applications to three red grape cultivars on total protein and amino acid contents were investigated. Total protein contents and amino acid pattern differed significantly depending on the cultivars. It was determined that the most abundant amino acid was glutamic in ‘Prima’ and ‘Lival’ cultivars, and arginine and proline in ‘Michele Palieri’. While MeJA and Rbf treatments increased the protein content of ‘Prima’ cultivar, they decreased the protein content of ‘Michele Palieri’. MeJA increased the content of 13 amino acids (aspartic acid, glutamic acid, glycine, arginine, alanine, proline, tryptophan, valine, methionine, isoleucine, leucine, phenylalanine, lysine) in ‘Prima’ and two amino acids (aspartic acid, methionine) in ‘Lival’ and only one (aspartic acid) in ‘Michele Palieri’. On the other hand, seven amino acids of ‘Lival’ and 14 amino acids of ‘Michele Palieri’ were decreased by MeJA treatment. Compared to MeJA, the number of amino acids induced by Rbf was lower, being aspartic acid, glutamic acid and arginine in ‘Michele Palieri’ and only arginine in ‘Prima’.

在这项研究中，研究了对三种红葡萄品种叶面喷施茉莉酸甲酯 (MeJA) 和核黄素 (Rbf) 对总蛋白质和氨基酸含量的影响。总蛋白质含量和氨基酸模式因品种而异。确定了'Prima'和'Lival'品种中含量最高的氨基酸是谷氨酸，而'Michele Palieri'中含量最高的是精氨酸和脯氨酸。虽然 MeJA 和 Rbf 处理增加了“Prima”品种的蛋白质含量，但它们降低了“Michele Palieri”的蛋白质含量。MeJA增加'Prima'中13种氨基酸（天冬氨酸、谷氨酸、甘氨酸、精氨酸、丙氨酸、脯氨酸、色氨酸、缬氨酸、蛋氨酸、异亮氨酸、亮氨酸、苯丙氨酸、赖氨酸）和两种氨基酸（天冬氨酸、'Lival'中的蛋氨酸）和'Michele Palieri'中只有一种（天冬氨酸）。另一方面，'Lival'的7个氨基酸和'Michele Palieri'的14个氨基酸通过MeJA处理减少。与MeJA相比，Rbf诱导的氨基酸数量较少，'Michele Palieri'中为天冬氨酸、谷氨酸和精氨酸，而'Prima'中仅有精氨酸。
