“…Approximately 90% of the averaged total biomass of S. brachiata was comprised of aboveground components (Jagtap et al 2002). Live tissues were in most cases the major portion of the aboveground biomass, as observed other salt marsh species previously (Darby and Turner 2008;Palomo and Niell 2009;Negrin et al 2015). Belowground biomass was diverged from aboveground biomass in seasonal pattern (Fig.…”

“…Whereas, ratio between shoot to root ranged from 16 to 36 on fresh weight basis and 5 to 11 on dry weight basis in Salicornia europaea at South-West of Netherlands (Stienstra 1987). A reduced belowground was associated with stressful soil conditions due to the salinity (Negrin et al 2015) because salinity influence the relative allocation of resources.…”

The present study determined the plant biomass (aboveground and belowground) of Salicornia brachiata from six different salt marshes distributed in Indian coastal area over one growing season (September 2014–May 2015). The nutrients concentration and their pools were estimated in plant as well as soil. Belowground biomass in S. brachiata was usually lower than the aboveground biomass. Averaged over different locations, highest biomass was observed in the month of March (2.1 t ha−1) followed by May (1.64 t ha−1), February (1.60 t ha−1), November (0.82 t ha−1) and September (0.05 t ha−1). The averaged aboveground to belowground ratio was 12.0. Aboveground and belowground biomass were negatively correlated with pH of soil, while positively with soil electrical conductivity. Further, there were positive relationships between organic carbon and belowground biomass; and available sodium and aboveground biomass. The nutrient pools in aboveground were always higher than to belowground biomass. Aboveground pools of carbon (543 kg ha−1), nitrogen (48 kg ha−1), phosphorus (4 kg ha−1), sodium (334 kg ha−1) and potassium (37 kg ha−1) were maximum in the month of March 2015. Bioaccumulation and translocation factors for sodium of S. brachiata were more than one showing tolerance to salinity and capability of phytoremediation for the saline soil.

“…The reduction in biomass of S. brachiata during the last phenological stage might be related to the high soil salinity and temperature (Rey et al, 1990). Negrin et al (2015) suggested that high salt concentration in soil significantly influences the relative allocation of resources. Additionally, the decreased belowground biomass at SCS and DS (Figure 3) might be because of the seed formation and seasonal resource translocation from below to upper parts (Darby & Turner, 2008; Palomo & Niell, 2009).…”

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 À2 and 0.12-15.91 g m À2 , respectively while the highest above-and belowground biomass was documented at the senescence start stage. The nutrient contents of C, N, P, Na + , K + , Ca 2+ , Mg 2+ , and Cl À 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 À2 ), phosphorus (0.40 g m À2 ), sodium (39.81 g m À2 ), potassium (3.76 g m À2 ), magnesium (2.85 g m À2 ), and chloride (64.66 g m À2 ) 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 saltaffected 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.

They are recognized as major productive ecosystems globally and play many functions like nutrient cycling, biodiversity support, carbon sequestration, water quality improvement, and many more (Castillo et al., 2008;Chaudhary et al., 2018). These ecosystems have colonization of different halophytes that serve as carbon sources in the coastal ecosystem for organic matter production and work as a net sink of CO 2 ,

“…La biomasa vegetal aérea total varió entre niveles de la marisma y entre estaciones del año, siendo en verano significativamente mayor que la registrada en primavera e invierno, principalmente en la marisma baja de todas las localidades. La biomasa promedio de Sarcocornia perennis fue en general mayor que la reportada por Negrin et al (2015) para la marisma de Bahía Blanca, excepto la registrada en la marisma alta de Bahía San Julián que fue más baja. Un factor importante en la variabilidad de la producción de las marismas entre diferentes áreas geográficas es la amplitud de las mareas, encontrándose que la producción neta de biomasa se ve incrementada al aumentar la amplitud del rango de mareas, aparentemente debido a un aumento en la disponibilidad de nitrógeno (McLusky y Elliot, 2004).…”

La zona costera de la Patagonia austral, caracterizada por un régimen macromareal, permite el desarrollo de extensas marismas tanto en estuarios como en bahías, que han sido muy poco estudiadas. Con el objetivo de caracterizar las marismas del sur de Santa Cruz, identificar las principales asociaciones vegetales que las componen y analizar las variaciones de la biomasa vegetal en relación al nivel de marea y la época del año, se realizaron muestreos en primavera (noviembre 2015), verano (febrero 2016) e invierno (agosto de 2016) en la bahía San Julián y los estuarios de los ríos Santa Cruz, Coyle y Gallegos. Los muestreos se realizaron empleando un diseño aleatorio estratificado, dividiendo la marisma en tres niveles: alta, media y baja. Se recolectaron seis muestras de 0,25 m2 en cada nivel y se determinó el porcentaje de cobertura de cada especie y su biomasa aérea (peso seco). Se determinó también la granulometría y la materia orgánica del sedimento (%). Los datos se analizaron mediante ANOVA factorial (sitios, nivel, estación del año). El sustrato en todas las localidades y niveles estuvo constituido principalmente por limos-arcillas (54 a 88%) y arena fina (20 a 44%). La materia orgánica varió entre 4,5 y 7,1%. Se registraron cinco especies vegetales: Sarcocornia perennis, Puccinellia glaucescens, Suaeda argentinensis, Limonium brasiliense y Spartina sp. S. perennis fue la especie dominante en casi todos los sitios y niveles, con excepción de la marisma alta y la marisma media de Bahía San Julián, donde codomina junto a Limonium brasiliense, y la marisma baja del estuario del río Santa Cruz, donde codomina junto a Spartina sp. La biomasa vegetal aérea total alcanzó su valor máximo (1700 g m-2) durante el verano en la marisma baja del estuario del río Gallegos y correspondió en su totalidad a S. perennis. El valor más bajo de biomasa total (177 g m-2) fue registrado en la marisma alta de Bahía San Julián durante el invierno y correspondió en un 33,8% a S. perennis. La cobertura de S. perennis varió entre 23 y 100%, siendo siempre mayor en la marisma baja. Spartina sp. se encontró únicamente en la marisma baja del estuario del río Santa Cruz, sitio que constituye el registro más austral para esta halófita en la costa Argentina.
