“…Similarly, in the study with two obligate halophytes, Sesuvium portulacastrum and Tecticornia indica , total Chl contents were significantly enhanced in both species grown under 200 mM and 400 mM NaCl ( Rabhi et al, 2012 ). In the study with two purslane genotypes, Zaman et al (2019) found that with the increase of NaCl concentrations from 0 to 200 mM, total Chl content decreased. In this study, higher salinity also resulted in lower Chl content in purslane ( Figure 6A ).…”

“…Low productivity of purslane under higher salinity, such as 200 and 300 mM NaCl, could mainly be due to its slow leaf growth and development supported by the lower total number of leaves ( Figure 4A ) and smaller TLA ( Figure 4B ). In the study with two purslane genotypes, Zaman et al (2019) reported that leaf numbers were significantly decreased in the main stem in both genotypes when grown with high concentration of NaCl due to excess accumulation of salt during the development of leaf. This study also showed that plants grown with 0 and 100 mM NaCl had similar but significantly higher SLA compared to those grown with 200 and 300 mM NaCl ( Figure 4C ).…”

“…Salinity stress could affect the photosynthetic performance due to salt accumulation in leaves ( Munns and Tester, 2008 ) and the deceases in total Chl ( Parida et al, 2002 ; Stepien and Johnson, 2009 ; Duarte et al, 2013 ; Zaman et al, 2019 ). In the study of the glycophyte Arabidopsis and the halophyte Thellungiella, Stepien and Johnson (2009) found that the Chl content of Arabidopsis continuously declined when exposed to salt while there was no significant change in the Chl content of Thellungiella when exposed to same salinity conditions.…”

Portulaca oleracea L. (known as purslane) is one of the most nutritious leafy vegetables owing to its high content of antioxidants. In this study, all plants were grown indoors hydroponically with different NaCl salinities. Photosynthetic photo flux density (PPFD) at 200 μmol m−2 s−1 (12 h) was provided to all plants by LED with red:blue ratio of 2.2. Thirty days after transplanting, plants grown with100 mM NaCl had the highest productivity and the fastest leaf growth followed by those with 0, 200 and 300 mM NaCl. Grown with 300 mM NaCl, purslane had the lowest specific leaf area due to its highest leaf dry matter content and its lowest water content. All plants had similar values of leaf succulence except for those with 300 mM NaCl. Total chlorophyll and carotenoids contents were significantly higher in plants grown with 0 and 100 mM NaCl than with 200, and 300 mM NaCl. All plants had Fv/Fm ratios close to 0.8. However, electron transport rate and ΔF/Fm′ were significantly higher in plants grown with 0 and 100 mM NaCl than with 200 and 300 mM NaCl. CAM-induced purslane with 300 mM NaCl had higher non-photochemical quenching. Maximum net photosynthetic O2 evolution rate and Cyt b6f concentration were significantly lower with 300 mM NaCl compared to all other plants while all plants had similar PS II concentration. Proline concentration increased with increasing salinities. All plants had similar levels of total soluble sugars. Plants grown with 0 and 100 mM NaCl had significantly higher concentrations of NO3−, total reduced nitrogen, total leaf soluble protein, Rubisco protein, total ascorbic acid, and total phenolic compounds than with 200 and 300 mM NaCl. The highest concentrations of K, Ca, and Mg were found in purslane grown under 0 mM NaCl. Statistically, no significant differences in Fe concentrations were observed among all plants. However, salinity seems to increase Fe concentration. In conclusion, it is feasible to grow purslane under 100 mM NaCl as it is the most optimal condition to achieve higher productivity and better quality. However, the production of antioxidants may depend on not only salinity but also other growth conditions.

“…Grain yield of L. iberica and L. royleana plants decrease in severe drought stress due to the reduction of photosynthetic materials [14]. Previous research has shown that water deficits cause a reduction in grain yield, oil percentage, and PUFA composition, including that of linolenic acid, linoleic acid, palmitic acid, and oleic acid in purslane [15]. Likewise, similar alterations have been shown in Oenothera biennis L. [16], sunflower, safflower, sesame [7], and purslane [17].…”

Background: Application nano iron chelate and AMF fertilizer can increase plants' tolerance against water deficit stress. The main objectives of the current study were to investigate the effect of arbuscular mycorrhizal fungi (AMF) and nano iron chelate fertilizer under drought stress on grain yield, leaf chlorophyll contents, root colonization, oil percentage, and fatty acids profile of Lallemantia species. The experiment was carried out as a factorial based on a complete randomized block design consisting of three factors of irrigation levels of 90 (I90), 60 (I60), and 30% (I30) depletion of available soil water (ASW)), fertilizer levels of control (no fertilizer), AMF inoculation, and nano iron chelate, and plant species of Lallemantia (L. iberica and L. royleana) at the Research Farm of College of Agriculture, Shahed University, Tehran, Iran, in 2018/2019. Results: The results showed that increasing water deficit stress significantly decreased the above traits while applying nano iron and AMF fertilizers significantly increased them across water treatments. AMF fertilizer inoculation significantly improved both species yield. Higher root colonization by AMF inoculation enhanced seed oil and fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, and Eicosenoic acid). In contrast, applying nano iron chelate by increasing chlorophyll content in any irrigation regime could enhance seed oil and some fatty acids such as palmitoleic acid. Conclusions: Water deficit stress and application of fertilizers had different effects on both species. L. iberica, compared to L. royleana, had the most tolerance to water deficit stress and the highest dependence on AMF inoculation. Overall, these results demonstrated that the application of AMF could improve major features of Lallemantia species under deficit irrigation conditions, especially at the I60 irrigation level.

“…On the one hand, fatty acids have important physiological functions and are the main precursors for synthesizing some signal molecules and aroma esters [ 16 ]. On the other hand, fatty acids can prevent mechanical damage and heat emission together with other substances [ 17 , 18 ]. Further, fatty acids are important nutrients that can lower blood pressure, increase lipoprotein and apolipoprotein levels, and reduce body weight [ 19 , 20 , 21 ].…”

Zanthoxylum plants, important aromatic plants, have attracted considerable attention in the food, pharmacological, and industrial fields because of their potential health benefits, and they are easily accessible because of the wild distribution in most parts of China. The chemical components vary with inter and intraspecific variations, ontogenic variations, and climate and soil conditions in compositions and contents. To classify the relationships between different Zanthoxylum species and to determine the key factors that influence geographical variations in the main components of the plant, the fatty acid composition and content of 72 pericarp samples from 12 cultivation regions were measured and evaluated. Four fatty acids, palmitic acid (21.33–125.03 mg/g), oleic acid (10.66–181.37 mg/g), linoleic acid (21.98–305.32 mg/g), and linolenic acid (0.06–218.84 mg/g), were the most common fatty acid components in the Zanthoxylum pericarps. Fatty acid profiling of Zanthoxylum pericarps was significantly affected by Zanthoxylum species and geographical variations. Stearic acid and oleic acid in pericarps were typical fatty acids that distinguished Zanthoxylum species based on the result of discriminant analysis (DA). Palmitic acid, palmitoleic acid, trans-13-oleic acid, and linoleic acid were important differential indicators in distinguishing given Zanthoxylum pericarps based on the result of orthogonal partial least squares discriminant analysis (OPLS-DA). In different Zanthoxylum species, the geographical influence on fatty acid variations was diverse. This study provides information on how to classify the Zanthoxylum species based on pericarp fatty acid compositions and determines the key fatty acids used to classify the Zanthoxylum species.
