“…The difference in water uptake response to salinity change between S. glauca and S. bigelovii could directly affect their plant succulence (i.e., amount of water per unit dry mass) and thereby biomass accumulation. When external NaCl concentrations decreased from 200 to 6-10 mM, plant succulence was reduced in S. bigelovii (Kong and Zheng, 2014b), but not in S. glauca since this species showed no differences in both fresh and dry weight among different NaCl treatments. Both Suaeda and Salicornia are succulent halophytes (Brown et al, 1999), and succulence is not only a mechanism to dilute excess NaCl in leaf tissues (Glenn et al, 1999), but could also be a major contributor to biomass accumulation in these halophytes (Flowers and Colmer, 2008;Rozema and Schat, 2013).…”

“…The optimal salinity levels for the growth of many halophytes have been shown to be 50-250 mM NaCl (Flowers and Colmer, 2008). Suboptimal NaCl concentration may reduce plant growth, which is especially evident in hydroponic system studies; for example, 5-10 vs. 200 mM NaCl has reduced growth rate and biomass accumulation in hydroponic S. bigelovii (Ayala and O'Leary, 1995;Kong and Zheng, 2014b). However, unlike S. bigelovii, in the present study of hydroponic S. glauca, 6-10 mM NaCl did not inhibit plant growth compared with 200 mM NaCl.…”

“…Halophytes use the controlled uptake of Na + , balanced by Cland other anions, into cell vacuoles to drive water uptake into the plant against a low external water potential (Glenn et al, 1999). With the decrease of external NaCl concentrations, some halophytes like S. bigelovii not only decrease Na + absorption, but also reduce water consumption (Kong and Zheng, 2014b). However, water consumption by S. glauca was not reduced when external NaCl concentrations decreased from 200 to 6-10 mM.…”

Suaeda glauca is an annual halophyte growing in saline–alkali environment in North China. To evaluate the potential of producing S. glauca as a vegetable at moderate NaCl concentrations, plants were grown in nutrient solutions with 6, 8, and 10 mm NaCl, and with 200 mm NaCl as a control. Results showed that main stem length, true leaf number, side branch number, and canopy width of plants in 6–10 mm NaCl were not significantly different from those in 200 mm. Also, no significant differences in fresh and dry weights of individual plants, marketable yield, and water use efficiency of the plants were observed between 6–10 and 200 mm NaCl treatments. Despite remarkable decreases in sodium uptake, similar water consumptions by the plants were obtained in 6–10 vs. 200 mm NaCl. The results suggest that S. glauca is a potential candidate for hydroponic production as a vegetable at moderate NaCl salinity, since growth attributes and biomass accumulation were not reduced when grown at lower salinity levels, despite with decreased sodium uptake.

“…Canopy temperature was measured using an infrared temperature meter (IR Temp Meter, Spectrum Technologies, Inc.; Aurora, IL, USA) at the conclusion of the experiment. Water use efficiency (WUE) was calculated as grams shoot fresh weight/irrigation volume [18]. Inflorescence measurements were taken starting with flower development in July.…”

Research has shown that reduced irrigation and fertilizer rates can still produce good plant growth when irrigation is applied efficiently to reduce leaching. The impact of reduced irrigation and fertilizer rate on flowering and plant growth would provide additional information on the potential for reduced production inputs. The objective of this research was to quantify the impact of reduced irrigation and fertilizer rate on growth and flowering of Ruby Candle beardtongue (Penstemon × ‘Ruby Candle’). A soil moisture sensor automated irrigation system was used to maintain plants at 40% volumetric water content [VWC; well-watered (WW)] or 18% VWC (reduced irrigation, RI). A controlled release fertilizer was applied at 100%, 50%, and 25% of the bag rate (12 g/plant). There was not a significant treatment effect on any flower parameter. Average plant height was greatest for plants receiving the 50% fertilizer rate (75.9 cm) and was lowest for the 100% fertilizer rate (64.5 cm). Internode length was greater for WW plants (36.9 mm) than RI plants (32.4 mm). Well-watered plants had greater fresh weight (99.1 g) than RI plants (79.2 g) and 100% fertilizer rate (97.1 g) was greater than the 25% fertilizer rate (82.7 g).

“…In such areas, freshwater irrigation becomes a limiting factor for other crops, but halophytes are well adapted to such conditions (Rozema and Schat 2013). The novel strategy of commercializing the halophytes which are hydroponically impinged with saline waters proved to be a viable and remarkable asset for agriculture industries (Kong and Zheng 2014), as these adapted plants accumulate high quanta of soluble salts in their shoot systems. Much focus is given globally on halophyte species on account of their pharmacological values and economic gains (ten Brink et al 2011); the halophytes of interest comprise of Atriplex, Cressa, Haloxylon, Panicum, Salvadora, Salsola, Suaeda, Tamarix, Trianthema, etc.…”

Salinity is one among the main culprits that hamper the capability of agricultural lands to sustain enormous world population. It occurs due to climate transformation, intensive agriculture, land degradation, floods, saltwater intrusion, etc. Saline soils are detrimental to crop growth thus resulting in lean agricultural yield, eventually turning fertile lands into barren lots. The halophytes are progressively acquiring the limelight in terms of food assurance on limited land resources coupled with expansion of saline-enriched landscapes. On the broader context, halophytes possess the potential to be exploited on a mass scale throughout the world because these are attributed with the ability to endure physical restraints of environment and successfully biosynthesize the highly nutritive
