摘　　要：对2018~2019年度江苏沿海海域5个站位、5个采收期(剪收次数)的条斑紫菜中氨基酸含量及对应的海水氮含量进行了检测,并分析了条斑紫菜中氨基酸的变化规律及其与海水氮含量的相关性。结果表明,5个站位条斑紫菜中的18种氨基酸具有不同程度的差异性,在各个站位间均呈极显著差异的氨基酸有天冬氨酸、丙氨酸、缬氨酸及脯氨酸;5个采收期条斑紫菜中的氨基酸含量总体上是差异显著的(P P 】0.05),在不同采收期间差异极显著(P P P 硝态氮 】氨态氮。This study investigated the variation of amino acids in Phycocalidia yezoensis at 5 stations, 5 har-vest periods from 2018 to 2019 in Jiangsu Province, and analyzed the correlation between the amino acids of samples and the nitrogen content in the water. The results showed that 18 kinds of amino acids of samples were various between 5 stations, among them, aspartic acid, alanine, valine and proline were presented highly significant difference in each station. The total amino acids showed highly significant difference between each other harvest period except the group between the December and the February, in addition, 18 amino acid presented highly significant difference in the groups between December and April, January and March, January and April, February and April. The content of essential amino acid in Phycocalidia yezoensis presented highly significant difference between the harvest period, and no significant difference between the stations. The ranking of the relevance was TN >NO3-N >NH4+-N.
