摘 要: | 以广泛分布在辽宁海岸线的翅碱蓬为研究对象,研究了不同浓度NaCl胁迫(0、100、200、300、400、500、600 mmol/L)对该植物色素积累的影响。结果表明,NaCl胁迫对翅碱蓬的叶绿素a、叶绿素b、总叶绿素、类胡萝卜素和甜菜红素含量的影响总体变化趋势是随盐浓度增加呈减小趋势。对照处理各种色素的含量均最高,之后随着NaCl浓度的升高叶绿素a、叶绿素b、总叶绿素的含量呈先增大后减小的趋势,说明低浓度NaCl胁迫相对促进叶绿素a、叶绿素b、总叶绿素含量的增加。本试验结果可为盐碱地的改良利用、沿海滩涂植被修复、翅碱蓬的作物化栽培及经济价值的开发利用提供一定的理论依据。

Effect of NaCl stress on the pigment accumulation of Suaeda Salsa L. |

Abstract: | Pigment accumulationS was compared under different concentrations of NaClS(0 mmol/L,S100 mmol/L,S200 mmol/L,S300 mmol/L,S400 mmol/L,S500 mmol/L,S600 mmol/L)S on Suaeda Salsa L. which widely distributed in the Liaoning coastSline in order to providing certain theoretical basis for improving saline alkali soil, restoring ScoastalSvegetation, developing itsScropScultivationSand economic value. The results were as following: The growths of seedlings for Suaeda physophora were promoted in the proper low concentration of NaCl solution and obviously inhibited in the higher salt concentration. |
