Ecophysiology of Sarcocornia neei (Amaranthaceae) from two wetlands of the central coast of Lima, Peru
Background and Aims: The wetlands of the central coast of Lima, Peru, are being negatively impacted by anthropic activity, because human settlements have been established in the vicinity of these fragile ecosystems.

| description | Background and Aims: The wetlands of the central coast of Lima, Peru, are being negatively impacted by anthropic activity, because human settlements have been established in the vicinity of these fragile ecosystems. Sarcocornia neei is a halophytic Amaranthaceae, which inhabits these wetlands and with potential to be used as food. However, it is being displaced by this human activities, while basic aspects of its biology remain unknown. Hence, our goal was to investigate the ecophysiology of this species, under greenhouse and laboratory conditions, looking at the possibility of being grown outside its natural environment.Methods: Plants of S. neei were collected in both Ventanilla and Paraíso Wetlands, Lima, Peru. For the germination test, 600 seeds were subjected to different concentrations of NaCl (0 M, 0.1 M, 0.3 M and 0.58 M), with three repetitions for 15 days. Cuttings were also planted in organic substrate and adding the same concentrations of salt, with three repetitions for four months. At the end of this period histological sections were made and protein extracts were also realized.Key results: A better germination was obtained in 0.3 M of NaCl. There were no significant differences in the growth of cuttings. Histological variations were found in the stems depending on the treatments and there were no significant differences in the total protein concentration, although overexpression of low molecular weight proteins was found in the treatment of 0.58 M NaCl.Conclusions: The results show that this species could be cultivated in saline lands and used in human or animal feed, or as a promising species in the decontamination of lead-contaminated saline soils. |

Antecedentes y Objetivos: Los humedales de la costa central de Lima, Perú, están siendo fuertemente impactados de forma negativa por actividad antrópica, debido a que se han establecido asentamientos humanos en las cercanías de estos frágiles ecosistemas. Sarcocornia neei es una Amarantácea halófita, que habita estos humedales, con potencial de ser usada como alimento; está siendo desplazada por la actividad humana y aún se desconocen aspectos básicos de su biología. Por lo tanto, nuestro objetivo fue conocer la ecofisiología de esta especie bajo condiciones de invernadero y de laboratorio, viendo la posibilidad de ser cultivada fuera de su ambiente natural.Métodos: Las plantas de S. neei fueron colectadas tanto en el Humedal de Ventanilla como en el de Paraíso, Lima, Perú. Para la prueba de germinación se usaron 600 semillas sometidas a diferentes concentraciones de NaCl (0 M, 0.1 M, 0.3 M y 0.58 M), con tres repeticiones por 15 días. También se plantaron esquejes en sustrato orgánico y adicionando las mismas concentraciones de sal, con tres repeticiones por cuatro meses. Al final de este periodo se realizaron cortes histológicos y también se hicieron extractos de proteínas.Resultados clave: Se obtuvo una mejor germinación en 0.3 M de NaCl. No hubo diferencias significativas en el crecimiento de los esquejes. Se encontraron variaciones histológicas en los tallos dependiendo de los tratamientos y no hubo diferencias significativas en la concentración total de proteínas, aunque sí se encontró una sobreexpresión de proteínas de bajo peso molecular en el tratamiento de 0.58 M de NaCl.Conclusiones: Los resultados muestran que esta especie podría ser cultivada en terrenos salinos y usada en la alimentación humana o de animales, o como especie promisoria en la descontaminación de suelos salinos contaminados con plomo.
