The present study aimed to examine the alteration in phenological parameters, above- and belowground biomass, nutrient contents, and nutrient pools at different phenological stages (seedling, vegetative, flowering, senescence start, senescence complete, and dry stage) of Salicornia brachiata Roxb. According to our results, plant height was significantly higher at the senescence start, senescence complete, and dry stages; however, the water content was significantly higher at the seedling stage. Furthermore, the above- and belowground biomass of S. brachiata was recorded in the range between 0.57–533.69 g m⁻² and 0.12–15.91 g m⁻², respectively while the highest above- and belowground biomass was documented at the senescence start stage. The nutrient contents of C, N, P, Na⁺, K⁺, Ca²⁺, Mg²⁺, and Cl⁻ in above- and belowground biomass were estimated and we found significant spatial and stage-wise variations. The aboveground pools of carbon (66.52 g m⁻²), phosphorus (0.40 g m⁻²), sodium (39.81 g m⁻²), potassium (3.76 g m⁻²), magnesium (2.85 g m⁻²), and chloride (64.66 g m⁻²) were higher at the senescence start stage. The averaged bioaccumulation and translocation factors for Na⁺ were 8.91 and 3.66, respectively which indicated the phytoremediation capacity of S. brachiata of salt-affected soils. The results of the present study witnessed significant changes in phenological parameters, above- and belowground biomass, nutrient contents, and their pools with the phenological stages of S. brachiata. Furthermore, present findings suggest that S. brachiata may be utilized for the coastal development program of India and rehabilitation of salt-affected soils.

Salicornia brachiata Roxb 物候参数、地上和地下生物量、养分含量及其池的变化与物候阶段

本研究旨在研究不同物候阶段（幼苗、营养、开花、衰老开始、衰老完成和干燥阶段）的盐角草的物候参数、地上和地下生物量、养分含量和养分库的变化。根据我们的结果，在衰老开始、衰老完成和干燥阶段，株高显着较高；然而，在苗期含水量明显较高。此外，S. brachiata的地上和地下生物量记录在 0.57–533.69 g m ^-2和 0.12–15.91 g m ^-2之间的范围内，而最高的地上和地下生物量记录在衰老开始阶段。估算了地上和地下生物量中C、N、P、Na ⁺、K ⁺、Ca ²⁺、Mg ²⁺和 Cl ^-的养分含量，我们发现了显着的空间和阶段变化。碳（66.52 g m ^-2）、磷（0.40 g m ^-2）、钠（39.81 g m ^-2）、钾（3.76 g m ^-2）、镁（2.85 g m ^-2）和氯化物（64.66 g m ^-）的地上池² ) 在衰老开始阶段较高。Na的平均生物蓄积和易位因子⁺分别为 8.91 和 3.66，表明S. brachiata对盐渍土壤的植物修复能力。本研究的结果见证了S. brachiata物候阶段的物候参数、地上和地下生物量、养分含量及其池的显着变化。此外，目前的研究结果表明，S. brachiata可用于印度的沿海开发计划和受盐分影响的土壤的恢复。
