In this study, primary investigations of selected cultivar of purslane named as Tall Green under articular salinity stress were evaluated to understand the basic concept of different mechanisms of physiological attributes which will play an important role for molecular and proteomic level research. The evaluation of morphological and physiological attributes under 0 mM (without salt addition) 100 mM and 200 mM salt stress changed dramatically. The results showed high salt stress at 200 mM significantly decreasing the morphological attributes and performance of leaves, stems, and roots. At moderate salt stress levels, 100 mM, the ratio of Fv/Fm slightly increased compared to high stress. In addition, salt stress significantly decreased the total chlorophyll content (chl a+b) at 200 mM. The relative water content percentage was high at 0 mM. Moreover, the electrolyte leakage (EL) significantly increased with increasing salinity stress compared to control 0 mM.
在这项研究中，评估了名为 Tall Green 的马齿苋选定品种在关节盐胁迫下的初步研究，以了解不同生理属性机制的基本概念，这些机制将在分子和蛋白质组学水平的研究中发挥重要作用。在 0 mM（不加盐）、100 mM 和 200 mM 盐胁迫下，形态和生理特性的评估发生了巨大变化。结果表明，200 mM 的高盐胁迫显著降低了叶片、茎和根的形态特性和性能。在中等盐胁迫水平 100 mM 时，与高胁迫相比，Fv/Fm 的比值略有增加。此外，盐胁迫显著降低了 200 mM 时的总叶绿素含量（chl a+b）。在 0 mM 时，相对水含量百分比较高。此外，与对照 0 mM 相比，电解质渗漏（EL）随盐胁迫的增加而显著增加。
