摘要/Abstract

摘要： 对Na₂CO₃胁迫下星星草幼苗游离氨基酸含量的研究结果表明,星星草幼苗游离氨基酸总含量随盐浓度的增加而增加。各组分中Ala、Cy s、Gly、leu、Met、Pro、Phe、Val的含量随着Na₂CO₃浓度的增加而增加,其中Ala、Cy s、Gly、leu、Met、Pro与Na₂CO₃浓度呈极显著正相关关系。Na₂CO₃胁迫下星星草幼苗体内氨累积,同时Asp-NH₂的含量明显增加,有效降低氨对幼苗的毒害。

Abstract: Contents of free amino acid of Puccinellia tenuiflora seedlings were studied under sodium carbonate stress. The results showed that free amino contents increased and had a positive correlationship with sodium carbonate concentration. Contents of Ala, Cys, Gly, Leu, Met, Pro, Phe and Val increased with increasing sodium carbonate concentration. Contents of Ala, Cys, Gly, Leu, Met and Pro had a significant positive correlationship with sodium carbonate concentrantion. Contents of NH₃ aaccumulated under Na₂CO₃ stress. In the meantime contents of Asp-NH₂ increased. It can reduce the harm of NH₃ to seedlings and enhance salt-alkali resistance.

Key words: Puccinellia tenuiflora seedlings, free amino acid contents, sodium carbonate stress, contents of NH₃, contents of Asp-NH₂
