“…It was reported that the increased levels of Na + and concomitant decreasing levels of K + in shoots respond to the competition of Na + with K + for the same binding sites, and therefore interfere with the transport of potassium in the cell [26]. This study results demonstrated that the K + content did not vary significantly among salt levels in A. argentina, A. crenatifolia and A. lampa, which agreed with results found for A. canescens [1,21,35]. Only in A. nummularia, the K + concentration was reduced by the increase salinity level.…”

“…There was a steady increase in the percentage of ashes of plants as an increase of the inorganic ions on plants. Several authors reported similar results in other Atriplex species, such as A. patula [17], A. prostata [10], A. canescens [21,35] and A. griffithii [11]. A. lampa was the only specie where the increase percentage of ashes was not significant, however in the other species, there was a significant increase of ashes, reaching the maximum values of 21% in A. crenatifolia and 29.50% in A. nummularia at 4% salinity level and 30.83% in A. argentina at 2% NaCl treatment.…”

Salinity is a major stress that adversely affects growth and productivity in plants. There are species that tolerate this stress within the genus Atriplex. Four species, A. lampa, A. crenatifolia, A. nummularia and A. argentina were compared for their ion accumulation and water relations under saline conditions. A greenhouse study was conducted by irrigating the four species with NaCl solutions at concentrations 0%, 1%, 2% and 4% starting when plants were six months old. Plants were harvested 45 d after starting the salinity treatments and analyzed for their ion contents. In the four Atriplex species, Na + and Cl -contents in plants increased, while Ca 2+ and Mg 2+ decreased with the increase of salinity in the irrigation solution. The results suggested that A. argentina and A. nummularia were able to maintain a higher leaf relative water content (RWC) at low leaf water potential, which was associated with a greater capacity of osmotic adjustment. A. lampa showed lower ion accumulation and minor osmotic adjustment than the other species. It can be concluded that the accumulation of ions favors the lower osmotic potential and contributes to osmotic adjustment in these halophytes.

“…However, Na is required for growth and development by some plants, such as some C4 species [3]. As early as 1960, Na was found to be necessary for efficient growth of halophytic plants, such as halogenton [4], and more recently for Atriplex acanthocarpa (a saltbush species) [5]. In glycophytic plants, Na is preferentially absorbed compared to K and, under salinity, Na + inhibits K + uptake and displaces K + from its cellular binding sites [6] and can become cytotoxic.…”

Two spinach (Spinacea oleracea L.) cultivars were evaluated for their response to deficient (0.25 mmol c L −1 or 0.25 K) and sufficient (5.0 mmol c L −1 or 5.0 K) potassium (K) levels combined with salinities of 5, 30, 60, 90, and 120 mmol c L −1 NaCl. Plants substituted K for Na proportionally with salinity within each K dose. Plants favored K + over Na + , regardless of salinity, accumulating significantly less Na at 5.0 K than at 0.25 K. Salinity had no effect on N, P, and K shoot accumulation, suggesting that spinach plants can maintain NPK homeostasis even at low soil K. Ca and Mg decreased with salinity, but plants showed no deficiency. There was no Na + to K + or Cl − to NO 3 − competition, and shoot biomass decrease was attributed to excessive NaCl accumulation. Overall, 'Raccoon' and 'Gazelle' biomasses were similar regardless of K dose but 'Raccoon' outproduced 'Gazelle' at 5.0 K at the two highest salinity levels, indicating that 'Raccoon' may outperform 'Gazelle' at higher NaCl concentrations. At low K, Na may be required by 'Raccoon', but not 'Gazelle'. This study suggested that spinach can be cultivated with recycled waters of moderate salinity, and less potassium than recommended, leading to savings on crop input and decreasing crop environmental footprint.

“…was an extremely efficient Na accumulator. Furthermore, several other Atriplex species have been shown to accumulate significant amounts of Na and Cl in saline conditions, increasing the likelihood of success of intercropping with garden orache to remove salts in the rootzone [31,36,37]. Results from RGR RR showed that, when compared to the 0 dS m −1 control, orache and saltwort showed the only positive growth at 3 dS m −1 and at 6 dS m −1 orache was the only species that showed a RGR RR above 1 (Figure 1).…”

Saline irrigation water can lead to salt buildup and reduced crop yields. Halophytic plants are known to accumulate excess salts in tissues, removing them from the immediate environment. This two-phase experiment explored the feasibility of intercropping watermelon (Citrullus lanatus (Thunb.) Matsum. and Nakai var. lanatus) with halophytic species to mitigate the negative effects of saline irrigation water while providing a value-added crop. In the first experiment, six greenhouse-grown species were irrigated with water that was either deionized (0 dS m −1) or contained 3 or 6 dS m −1 of salts for 41 days and screened for growth and salt removal. Two halophytes were selected to be additively intercropped with watermelon under field conditions and irrigated with the same saline irrigation levels as the first experiment. Results indicated that garden orache (Atriplex hortensis L.) exhibited the highest growth rates and purslane (Portulaca oleracea L.) accumulated high amounts of sodium in plant tissues under saline irrigation. The field experiment showed that watermelon yields, stem water potential, and fruit quality were not affected by saline irrigation; however, the watermelon/orache intercropping treatment had significantly higher yields. These results suggest intercropping with halophytes has the potential to contribute a value-added crop without reducing watermelon yields.
