“…In agreement with this, a significant increase in carbon content was detected in the three annual species but not in A. halimus under salinity (Figure 5). These results are in contrast to the findings of previous studies that found a biomass decrease in A. hortensis already at 78 [47,68] and 250 mM [48,69], and in A. halimus already at 160 [70] and 300 mM [71][72][73], while Yepes et al [74] did not detect a biomass decrease up to 300 mM in A. halimus.…”

The C4 Atriplex halimus vs. the C3 Atriplex hortensis: Similarities and Differences in the Salinity Stress Response

Soil properties and the ability to sustain agricultural production are seriously impaired by salinity. The cultivation of halophytes is seen as a solution to cope with the problem. In this framework, a greenhouse pot experiment was set up to assess salinity response in the perennial C4 species Atriplex halimus, and in the following three cultivars of the annual C3 Atriplex hortensis: green, red, and scarlet. The four genotypes were grown for 35 days with water salinity (WS) ranging from 0 to 360 mM NaCl. Plant height and fresh weight (FW) increased at 360 vs. 0 WS. The stomatal conductance (GS) and transpiration rate (E) were more severely affected by salinity in the C4 A. halimus than in the C3 species A. hortensis. This was reflected in a lower leaf water potential indicating stronger osmotic adjustment, and a higher relative water content associated with more turgid leaves, in A. halimus than A. hortensis. In a PCA including all the studied traits, the GS and E negatively correlated to the FW, which, in turn, positively correlated with Na concentration and intrinsic water use efficiency (iWUE), indicating that reduced gas exchange associated with Na accumulation contributed to sustain iWUE under salinity. Finally, FTIR spectroscopy showed a reduced amount of pectin, lignin, and cellulose under salinity, indicating a weakened cell wall structure. Overall, both species were remarkably adapted to salinity: From an agronomic perspective, the opposite strategies of longer vs. faster soil coverage, involved by the perennial A. halimus vs. the annual A. hortensis cv. scarlet, are viable natural remedies for revegetating marginal saline soils and increasing soil organic carbon.

“…Nevertheless, the response to the salinity of C. maritimum is population-dependent, being this trait often correlated with the growth of the plants in their natural habitat [29]. The leaf area was reduced under 150 mM NaCl, in agreement with previous results of Hamed et al [29], provoking a reduction of the specific leaf area and consequently an increase in leaf thickness and succulence (measured as leaf FW:leaf area ratio [31], the latter being one of the major factors involved in plant salt tolerance, the main quality trait for stimulated growth in halophytes [32]. However, Jiménez-Becker et al [14] detected a decrease in leaves FW:DW ratio (leaves succulence) together with a decrease in plant water content in the plants grown with 300 mM with respect to that of those grown with 100 mM NaCl; therefore, the salt concentration in the nutrient solution is one of the main factors to consider in leaf succulence of halophytes plants.…”

In this study, the effect of salinity (150 mM NaCl) compared to a control (9 mM NaCl) on growth, quality and shelf-life of fresh-cut sea fennel was evaluated. For that, sea fennel plants were cultivated in a hydroponic floating system and the sea fennel leaves were stored for 12 days at 5 °C. At harvest, leaves from plants grown in salinity had a lower content of NO3−, K+ and Ca2+ and an increased Cl− and Na+ concentration when compared to the control. There was a positive effect in the aerial part with increased fresh weight due to salt stress, but a reduction in the root biomass. During storage, weight loss and colour changes were not significant while leaves’ firmness was higher for control and increased during storage, probably due to lignification. Microbial growth (psychrophiles, yeast and moulds and enterobacteria) was higher at harvest for control and increased during storage, with no differences between treatments after 12 days at 5 °C. Sensory quality was similar for both treatments but leaves from NaCl treatment had a salty taste that was easily detected by panelists. These results show that saline-nutrient solution applied in hydroponics is a suitable system for sea fennel growth. It gives a slightly salty but high-quality product, acceptable as a “ready-to-eat” vegetable.

“…El estrés salino afecta cada aspecto de la fisiología y metabolismo de la planta y específicamente la toxicidad por sodio (Na+) es uno de los factores de estrés ambiental más perjudicial que afecta el crecimiento y productividad de los cultivos en todo el mundo [11] [12] [13 [14], debido a que disminuye la habilidad de absorber agua y una vez el Na+ y el cloro (Cl-) son absorbidos por la raíz en altas cantidades, ambos afectan negativamente el crecimiento, pues afectan los procesos metabólicos y disminuye la eficiencia fotosintética [10] [15] [9] El tomate es un cultivo moderadamente tolerante a la salinidad del suelo [16] así como del agua de riego, sin embargo su germinación y producción pueden verse afectadas hasta en un 50% bajo condiciones salinas de 8 dS/m (aproximadamente 80 mM) [17] [18] [19]. Concentraciones de 80 mM afectan drásticamente a las plantas e inclusive en 35 mM de NaCl se afecta el uso eficiente del agua [20] debido a que la concentración de sal conlleva al desequilibrio osmótico entre la zona radicular de la planta y el suelo, lo que produce disminución en la absorción de agua y por lo tanto de nutrientes minerales como K+, Ca2+, nitratos y fosfatos [21].…”

Bajo condiciones normales de campo, las plantas de cultivo interactúan con un gran número de factoresbióticos y abióticos que condicionan sus límites de productividad constituyéndose muchas veces en factoresestresantes que desvían el óptimo vegetal. Este artículo evaluó la sensibilidad de las plantas de tomate a estrésinducido por sales de NaCl y el hongo Fusarium oxysporum (Orden Hypocreales, Familia Nectriaceae) bajocondiciones de invernadero. Se realizó una fase de aislamiento e identificación del hongo en laboratorio,y luego fue inoculado en plántulas de tomate (Solanum lycopersicum L.) (Familia Solanaceae) variedadCalima. Las plántulas fueron sembradas en materas con sustrato tierra cascarilla de arroz estéril y 15 díasdespués del establecimiento, se iniciaron los tratamientos con sales 20, 40 y 80 mM de NaCl de maneragradual, hasta que se completara la dosis para cada tratamiento. El testigo se regó únicamente con agua. 110días después de la siembra, se evaluó la biomasa seca, se midió la clorofila con un clorofilómetro, el áreafoliar y la conductividad eléctrica en solución del suelo con un conductímetro. El peso seco total, el áreafoliar, índice en la concentración de la clorofila se redujeron a medida que aumentaba concentración salina yel efecto del hongo. El peso específico foliar, la eficiencia en el uso del agua y la conductividad eléctrica fuemayor en las plantas afectadas por los dos factores. La aplicación simultanea de los dos factores estresantes,Fusarium oxysporum y la concentración de NaCl, incrementaron el efecto de cada uno de ellos e indujeronun mayor nivel de estrés en las plantas de tomate variedad Calima.
