Salicornia brachiata (Roxb.) exhibits seed germination and grows luxuriantly under extremely saline conditions. We hereby report seed germination potential, seedling growth and seedling development associated physiochemical changes in S. brachiata. Seawater above 75 % strength, NaCl above 400 mM and PEG above 20 % reduced seed germination by 50 % in S. brachiata. Germination energy, coefficient of velocity of germination, relative salt injury, and different germination indexes decreased with stress strength. NaCl at 1000 mM and PEG at 40 % completely inhibited seed germination in S. brachiata. In recovery studies, 100 % seeds germinated once the inhibitory stress was removed. S. brachiata exhibited a significantly higher seed vigor index under 75 % strength of seawater and 200 mM NaCl. Malondialdehyde accumulation during seedling development was in accordance with the accumulation of reactive oxygen species (ROS). Sugar, free amino acid, and proline contents varied with seedling development and type of stress. Higher accumulation of polyphenols and flavonoids during seedling development helped to reduce the ROS accumulation. Accumulation of inorganic ions varied and S. brachiata maintained the ratio of K⁺/Na⁺ once the seedling is established. S. brachiata exhibited comparatively higher activity of the studied cell wall hydrolases, which helped to maintain hydration and elasticity of cell wall during seed germination and seedling development. Differentially higher activity of superoxide dismutase, guaiacol peroxidase and glutathione oxidase during seedling development under stress conditions helped to reduce the ROS accumulation. The results indicated that among stress solutions of similar osmolarity, maximum inhibition was observed in the seawater and it was followed by NaCl and PEG at seed germination stage.

Salicornia brachiata（Roxb。）表现出种子发芽，并且在极端盐碱条件下茂盛生长。我们在此报告腕带链霉菌的种子发芽潜力，幼苗生长和幼苗发育相关的理化变化。海水在75％以上的强度，上述的NaCl 400 mM和PEG 20％以上减少了种子发芽通过在50％的S. brachiata。发芽能量，发芽速度系数，相对盐害和不同的发芽指数均随胁迫强度而降低。NaCl（1000mM）和PEG（40％）完全抑制臂沙。种子的萌发。在恢复研究中，一旦消除抑制性胁迫，100％的种子就会发芽。腕带链球菌在75％的海水和200 mM的NaCl浓度下，种子的活力指数显着提高。幼苗发育过程中丙二醛的积累与活性氧（ROS）的积累一致。糖，游离氨基酸和脯氨酸含量随幼苗发育和胁迫类型而变化。幼苗发育期间多酚和类黄酮的较高积累有助于减少ROS的积累。幼苗建立后，无机离子的积累会发生变化，腕带沙门氏菌会保持K ⁺ / Na ⁺的比例。腕带链球菌表现出较高的活性研究的细胞壁水解酶，这有助于在种子发芽和幼苗发育过程中保持细胞壁的水合作用和弹性。在胁迫条件下幼苗生长过程中，超氧化物歧化酶，愈创木酚过氧化物酶和谷胱甘肽氧化酶的差异性较高活性有助于减少ROS的积累。结果表明，在渗透压相似的胁迫溶液中，在海水中观察到最大的抑制作用，在种子萌发阶段，其次是NaCl和PEG。
