A survey of leaf soluble amino acids was conducted for four subtropical seagrasses grown at several salinities. Proline functioned as an organic osmoticum in Halodule wrightii Aschers., Thallasia testudinum Banks ex Koenig, and Ruppia maritima L., while alanine functioned in an osmoregulatory capacity in Halophila engelmanni Aschers. When light-and salinity-induced variations in leaf NH(4) and amide-N levels were compared in Halodule, Thalassia, and Halophila, ability to regulate leaf NH(4) levels was correlated with osmoregulatory capacity and maintenance of selected amino acid contents.
对在不同盐度下生长的四种亚热带海草的叶片可溶性氨基酸进行了调查。脯氨酸在互花米草、罗氏海韭菜和海菖蒲中起到有机渗透调节剂的作用，而丙氨酸在海菖蒲中起到渗透调节作用。当比较互花米草、罗氏海韭菜和海菖蒲叶片中 NH(4)和酰胺-N 水平的光和盐诱导变化时，调节叶片 NH(4)水平的能力与渗透调节能力和选定氨基酸含量的维持相关。
