“…Plant growth is related to photosynthetic performance and changes in carbon economy under saline conditions (Webster et al 2016;Asrar et al 2017). Salinity stress often results in biomass reduction as a survival strategy of plants which is related with failure in carbon assimilation (Fall et al 2017;Pompeiano et al 2017). In such situations, plants distribute higher assimilated carbon to energy and maintenance rather than development of plant parts (Asrar et al 2017).…”

“…In such situations, plants distribute higher assimilated carbon to energy and maintenance rather than development of plant parts (Asrar et al 2017). Photosynthetic rates are reported to be dependent to salinity concentration and duration of salt exposure (Fall et al 2017;Pompeiano et al 2017). A decrease in net CO 2 assimilation is related to stomatal closure to regulate transpiration rate and water use efficiency (Liu et al 2011).…”

“…Salinity often results in biomass reduction, which is ascribed to a decline in CO 2 assimilation in photosynthesis [ 19 , 20 , 21 , 22 , 23 , 24 ]. This decrease in net CO 2 assimilation may result from stomatal closure to reduce transpiration and increase water use efficiency under salinity [ 25 , 26 ].…”

Studies on obligate halophytes combining eco-physiological techniques and proteomic analysis are crucial for understanding salinity tolerance mechanisms but are limited. We thus examined growth, water relations, ion homeostasis, photosynthesis, oxidative stress mitigation and proteomic responses of an obligate halophyte Suaeda fruticosa to increasing salinity under semi-hydroponic culture. Most biomass parameters increased under moderate (300 mmol L−1 of NaCl) salinity, while high (900 mmol L−1 of NaCl) salinity caused some reduction in biomass parameters. Under moderate salinity, plants showed effective osmotic adjustment with concomitant accumulation of Na+ in both roots and leaves. Accumulation of Na+ did not accompany nutrient deficiency, damage to photosynthetic machinery and oxidative damage in plants treated with 300 mmol L−1 of NaCl. Under high salinity, plants showed further decline in sap osmotic potential with higher Na+ accumulation that did not coincide with a decline in relative water content, Fv/Fm, and oxidative damage markers (H2O2 and MDA). There were 22, 54 and 7 proteins in optimal salinity and 29, 46 and 8 proteins in high salinity treatment that were up-regulated, down-regulated or exhibited no change, respectively, as compared to control plants. These data indicate that biomass reduction in S. fruticosa at high salinity might result primarily from increased energetic cost rather than ionic toxicity.

“…Sodium (Na) is the primary soluble cation in majority of saline soils, especially in the coastal areas (Luo et al, 2018; Wang et al, 2014). Elevated salts will accelerate the land degradation by worsening the soil physical and chemical properties and subsequently the soil microorganism and plant growth (Fall et al, 2017; Liu et al, 2017). The remediation of coastal saline soil has become a challenging task for government and scientific researchers.…”

Rice cultivation has been found to be an effective and feasible approach for improving saline soils and increasing food production. Most studies on the improvement of rice cultivation on saline soil have focused on the several individual soil properties in the topsoil, and we know little about the importance of rice cultivation for improving multifunctionality in coastal saline soils. We investigated basic soil properties (soil physical sand content, soil physical clay content, pH, EC, soil organic carbon, total nitrogen, alkaline hydrolysis nitrogen, available potassium, available phosphorus), enzyme activities (urease, catalase, protease) and soil multifunctionality (SMF) in 0–20 cm, 20–40 cm, 40–60 cm, 60–80 cm and 80–100 cm soil layers with rice cultivated for 0 (tidal flat; CK), 20 (R20), 44 (R44) and 70 years (R70). We found that soil EC was alleviated markedly in the first 20 years after rice cultivation. Soil physical sand content, pH, EC and available potassium (AK) decreased while total nitrogen (TN), alkaline hydrolysis nitrogen (AN), urease (URE), catalase (CAT) activities and SMF increased with the increase in rice cultivation years. The highest soil total organic carbon (SOC) was shown in R44. Soil pH, EC, AK and physical sand content increased while SOC, TN, AN, enzyme activities decreased with the increase in soil depth. Redundancy (RDA) analysis showed soil physicochemical properties explained 97.53% of the variation in soil enzyme activities. Soil CAT, URE and protease (PRO) had a positive correlation with soil physical clay content, SOC, TN, AN and AP while negatively correlated with pH and AK. The increased SOC and clay content by rice cultivation might be the main reasons stimulating soil enzyme activities. In summary, long‐term rice cultivation could alleviate soil salinity, increased SMF down to 1 m, implying that rice cultivation effectively improved coastal saline soil, and the improvement could last for 70 years.
