The responses of Salicornia brachiata at six different phenological stages under different treatments (NPS: saline soil + sea water; NPM: saline soil + tap water; GS: non-saline soil + sea water; and GM: non-saline soil + tap water) were estimated by measuring the change in phenological parameters, biochemical as well as physiological characters and nutrient contents for six months (November 2015 to April 2016). In this study, we recorded significantly higher growth [plant height, shoot height and root length (except GM)], fresh weight and dry weight of S. brachiata plants at moderate salinity (NPM treatment). Therefore, we considered that the NPM treatment soil had the optimal level of salinity for the proper growth and development of this plant. The concentration of nutrients and biological molecules in S. brachiata were analyzed and found significant stage and treatment wise variations. The Na+, Cl and proline contents were higher in NPS and GS treatment plants which confirm their importance to combat salinity stress. The content of total soluble sugars, starch, free amino acids, polyphenols and proline increased with plant phenological stages and higher concentrations were recorded in the last two stages (5th and 6th months). The photosynthetic performance and concentration of photosynthetic pigments were reported significantly higher in GM treatment plants. The results of current study proved the importance of salt to complete successful life whereas higher salinity causes harmful effects. Furthermore, this study will be helpful to increase our understanding regarding the behaviour of S. brachiata under different soil and water salinity treatments.

Salicornia brachiata Roxb 的物候和生理生化变异。在不同的土壤和水处理(盐度)下

不同处理(NPS:盐渍土+海水;NPM:盐渍土+自来水;GS:非盐渍土+海水;GM:非盐渍土+自来水)6个不同物候阶段的盐角草的响应) 是通过测量六个月(2015 年 11 月至 2016 年 4 月)的物候参数、生化以及生理特征和营养成分的变化来估计的。在这项研究中,我们记录到S. brachiata显着更高的生长 [植物高度、地上部高度和根长(转基因除外)]、鲜重和干重中等盐度的植物(NPM 处理)。因此,我们认为 NPM 处理土壤具有适合该植物正常生长和发育的最佳盐度水平。分析了S. brachiata中营养物质和生物分子的浓度,发现了显着的阶段和处理方式的变化。NPS 和 GS 处理厂的 Na +、Cl -和脯氨酸含量较高,这证实了它们对抗盐胁迫的重要性。总可溶性糖、淀粉、游离氨基酸、多酚和脯氨酸的含量随着植物物候阶段的增加而增加,并且在最后两个阶段(5和6个月)。据报道,转基因处理厂的光合性能和光合色素浓度显着更高。当前研究的结果证明了盐对完成成功生活的重要性,而较高的盐度会导致有害影响。此外,这项研究将有助于增加我们对S. brachiata在不同土壤和水盐度处理下的行为的理解。
