“…Similarly, S is an integral part of several important compounds in plants, such as vitamins, coenzymes, and phytohormones (Li et al, 2020). In addition, Zn 21 reduces excessive Na 1 uptake under saline conditions by affecting the structural integrity and permeability of cell membrane (Tolay, 2021). However, Yildiz et al (2020) reported that Na 1 and Cl À ions compete with nutrients and lead to nutrient deficiency in plants.…”

Albizia julibrissin (mimosa tree) and Sophora japonica (Japanese pagoda tree) are drought-tolerant landscape plants; however, salinity responses of these two species are not well documented. The objective of this study was to investigate the morphological and physiological responses of these two species to three salinity levels in greenhouse conditions. Two studies were conducted in the summer/early fall of 2020 and the spring of 2021. In 2020, uniform plants were irrigated weekly for the first 2 weeks and every other day for the following 3 weeks with a nutrient solution at an electrical conductivity (EC) of 1.2 dS·m−1 as a control or saline solution at ECs of 5.0 or 10.0 dS·m−1. In 2021, plants were irrigated weekly for 8 weeks with the same treatment solutions as described previously. Albizia julibrissin and S. japonica survived in both experiments with minimal foliar salt damage (leaf burn or necrosis). Irrigation water at ECs of 5.0 and 10.0 dS·m−1 reduced plant height and dry weight (DW) of both species. In the fall experiment, A. julibrissin irrigated with a saline solution at an EC of 10.0 dS·m−1 had the highest reduction in plant height (61%) compared with the control. Albizia julibrissin and S. japonica irrigated with a saline solution at an EC of 10.0 dS·m−1 had 52% and 47% reductions in shoot DW compared with the control, respectively. In the spring experiment, compared with the control, there were 72% and 45% reductions in height of A. julibrissin and S. japonica, respectively, when irrigated with saline solution at an EC of 10.0 dS·m−1. In addition, compared with the control, A. julibrissin and S. japonica had 58% and 64% reductions in shoot DW, respectively, when irrigated with saline solution at an EC of 10.0 dS·m−1. Increasing salinity levels in the irrigation water also reduced leaf greenness [Soil Plant Analysis Development (SPAD)], leaf net photosynthesis rate (Pn), stomatal conductance (gS), and transpiration rate (E) of both species. Furthermore, sodium (Na+) and chloride (Cl−) concentrations in leaves were affected by elevated salinity levels in the irrigation water. Visual score, Pn, gS, and E negatively correlated to Na+ and Cl− concentrations in leaves. But Cl− accumulation had more impact on the growth of A. julibrissin and S. japonica. In summary, both species were tolerant to saline solution irrigation up to 5.0 dS⋅m−1 and moderately tolerant to saline solution irrigation up to 10.0 dS⋅m−1.

“…Basil ( Ocimum basilicum L.) is an important warm-season MAP with high potential to be integrated into a wealth of cropping systems [ 14 , 15 ]. The salinity tolerance of basil is considered low [ 16 ], and the variability of the responses depends on numerous factors that include the genotype, the growing medium and conditions, including the presence in the soil of microbes with either pathogenic or beneficial activity [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Such responses are multidimensional because they affect main parameters of economic importance, such as the leaf fraction on the total above-ground biomass, and the concentration and composition of secondary compounds, including the volatile organic fractions and the essential oil [ 14 , 26 , 27 ].…”

An Endophytic Fungi-Based Biostimulant Modulates Volatile and Non-Volatile Secondary Metabolites and Yield of Greenhouse Basil (Ocimum basilicum L.) through Variable Mechanisms Dependent on Salinity Stress Level

et al. 2021

Salinity in water and soil is one of the major environmental factors limiting the productivity of agronomic and horticultural crops. In basil (Ocimum basilicum L., Lamiaceae) and other Ocimum species, information on the plant response to mild salinity levels, often induced by the irrigation or fertigation systems, is scarce. In the present work, we tested the effectiveness of a microbial-based biostimulant containing two strains of arbuscular mycorrhiza fungi (AMF) and Trichoderma koningii in sustaining greenhouse basil yield traits, subjected to two mild salinity stresses (25 mM [low] and 50 mM [high] modulated by augmenting the fertigation osmotic potential with NaCl) compared to a non-stressed control. The impact of salinity stress was further appraised in terms of plant physiology, morphological ontogenesis and composition in polyphenols and volatile organic compounds (VOC). As expected, increasing the salinity of the solution strongly depressed the plant yield, nutrient uptake and concentration, reduced photosynthetic activity and leaf water potential, increased the Na and Cl and induced the accumulation of polyphenols. In addition, it decreased the concentration of Eucalyptol and β-Linalool, two of its main essential oil constituents. Irrespective of the salinity stress level, the multispecies inoculum strongly benefited plant growth, leaf number and area, and the accumulation of Ca, Mg, B, p-coumaric and chicoric acids, while it reduced nitrate and Cl concentrations in the shoots and affected the concentration of some minor VOC constituents. The benefits derived from the inoculum in term of yield and quality harnessed different mechanisms depending on the degree of stress. under low-stress conditions, the inoculum directly stimulated the photosynthetic activity after an increase of the Fe and Mn availability for the plants and induced the accumulation of caffeic and rosmarinic acids. under high stress conditions, the inoculum mostly acted directly on the sequestration of Na and the increase of P availability for the plant, moreover it stimulated the accumulation of polyphenols, especially of ferulic and chicoric acids and quercetin-rutinoside in the shoots. Notably, the inoculum did not affect the VOC composition, thus suggesting that its activity did not interact with the essential oil biosynthesis. These results clearly indicate that beneficial inocula constitute a valuable tool for sustaining yield and improving or sustaining quality under suboptimal water quality conditions imposing low salinity stress on horticultural crops.

“…In PC1, the positive correlation within S and Zn is well recognized since Zn−S bonds serve as structural braces in protein domains that participate in several molecule interactions [ 28 ]. In the same context, Zn application improved K uptake, under normal as well as saline conditions, by basil ( Ocimum basilicum L.) [ 29 ], while K was the unique element amongst those measured, which showed a positive correlation with S content in shoots of the Chinese cabbage, highlighting its role as a counter cation for sulfate during xylem loading and vacuolar storage in leaves [ 30 ]. In PC2, the positive correlations between Ca and Sr are explained by their similar chemical and physical properties as a result of the similarity of the outer electron structure of these elements [ 27 ].…”

This study evaluated the elemental composition of 25 herbal tea plants commonly used in infusions by Portuguese consumers and the contribution to the elemental daily intake of some essential elements. Hydrocotyle asiatica (L.), Matricaria chamomilla (L.), and Melissa officinalis (L.) samples are a rich source of K with around 6.0 mg g−1 while the Asteraceae Silybum marianum (L.) and Echinacea angustifolia (DC.) exhibited 4.9 and 5.6 mg g−1 Ca, respectively. The highest concentrations of S and Zn were noted in Hydrocotyle asiatica (L.), while the highest concentration of Sr was found in Cassia angustifolia (Vahl.). In general, a large variability in the concentrations among different families and plant organs had been observed, except Cu with levels around 30 μg g−1. The principal component analysis (PCA) showed positive correlations between Zn and S and Sr and Ca, also revealing that Hydrocotyle asiatica (L.), Echinacea angustifolia (DC.), Silybum marianum (L.), and Cassia angustifolia (Vahl.) samples, stands out about all other samples regarding the enrichment of macro and micronutrients. The elemental solubility of macronutrients in the infusion is greater than the micronutrient solubility, despite the contribution to the recommended daily intake was weak. As a whole, Cynara scolymus (L.) and Hibiscus sabdariffa (L.) are the species with the best elemental solubilities, followed by Hydrocotyle asiatica (L.). No harmful elements, such as As and Pb, were observed in both the raw material and the infusions.
