“…Furthermore, with the studies on wheat [28], Moringa peregrine [29], and Pimpinella anisum [30]; foliar spray with nano-Fe under salinity, increased the height, dry biomass, chlorophylls content as well as sugars content of plants. Fe, especially as nano-form, played pivotal roles in the activity of SOD and CAT under salinity in grape [19] and Linum usitatissimum [5] Similar results have previously been reported demonstrating the positive effects of nano-Fe foliar application on chlorophyll content, SOD activity, K/Na ratio as well as on proline and avonoids content of plants.…”

“…Overall results demonstrate the adverse effects of salinity stress on the growth potential and physiological responses of both Satureja species. Salinity reduces plants growth, photosynthesis potential, and productivity [5,7,19]. In Satureja species and under salinity; electrolytes leakage and MDA content were increased [7].…”

“…Under salinity, ROS over-generation triggers oxidative stress in cells. In addition to that, salinity by causing ionic stress, oxidative damage, and osmotic stress drastically retards the plant's normal metabolism [5]. Salt stress reduced the yield, essential oil, and proline content of Pelargonium graveolens [6].…”

“…Salt stress reduced the yield, essential oil, and proline content of Pelargonium graveolens [6]. Increased salt concentration inhibits plant growth through osmotic potential, unbalanced nutrient ratios, modulation of plant growth regulators, reduction of photosynthetic pigments, and drives cell wall deterioration [5,7, 8]. Under abiotic stress, the availability of essential nutrients and especially micro-elements strongly decline [9].…”

Background: The secondary metabolites from savory species are widely used in food and pharmaceutical industries. Salt accumulation in the growing medium adversely affects the growth and yield of plants. The hyper-availability of Na+ and Cl- triggers nutrient imbalances, leading to secondary ionic stress. Under salinity exposure, the reactive oxygen species (ROS) over-generation drives oxidative stress in cells. Moreover, when facing environmental stress factors; the availability of essential nutrients and especially micro-elements strongly declines. Foliar application of micro-nutrients principally as nano-form is a promising strategy in meeting the nutritional demands of plants under stress environments with progressive nutrient shortages. Nano-materials and the supply of nutrients as foliar treatments meliorate the growth, biochemical reactions, and nutrient use efficiency of plants under salinity. The idea with the present experiment was to assay the effects of nano-Fe (magnetized-Fe) and selenium foliar application on the growth and some physiological responses of two Satureja species under saline-sodic conditions.Results: When studying the foliar application of Se and nano-Fe (0 and 3 mg L-1) on Satureja mutica and Satureia spicigera via two separate experiments, under normal no-saline conditions; the highest catalase activity was recorded in magnetized-Fe treated plants in both species. Independent effects of foliar application and plant species influenced total phenolics and Mg content of leaves. Foliar sprays reduced MDA content in plant tissue. In the second experiment, foliar applications were evaluated under salinity conditions. No-saline × Se and magnetized-Fe treated plants attained the highest data for aerial parts biomass in S. spicigera.Conclusion: The results demonstrated that salinity adversely influenced the growth and physiological responses, nevertheless, foliar spray with Se and magnetized-Fe partially ameliorated the salinity depression on Satureja species.

“…The positive correlation found between ROS production and MDA accumulation indicated that the increased lipid peroxidation observed under salinity was a direct effect of ROS on polyunsaturated components of membranes. The excessive accumulation of superoxide anion, hydrogen peroxide and MDA are common responses to salinity already observed in many other plant species, such as in Linum usitatissimum L. [ 37 ] and Indian mustard [ 38 ] leaves, cotton [ 39 ] and lentil [ 40 ] seedlings and mung bean roots and leaves [ 41 ]. Our results showed that the application of CTS at low and medium MW to durum wheat seedlings exposed to salinity was able to effectively reduce the accumulation of ROS and, consequently, ameliorate the stability of the membranes, as demonstrated by the decrease induced in the MDA content.…”

The present study was carried out with the aim of (i) evaluating the effect of chitosan (CTS) on the growth of durum wheat under salinity and (ii) examining CTS-regulated mechanisms of salinity tolerance associated with the antioxidant defense system. To achieve these goals, durum wheat seedlings were treated with CTS at different molecular weight, low (L-CTS, 50–190 kDa), medium (M-CTS, 190–310 kDa) and high (H-CTS, 310–375 kDa). The results obtained show that exposure to 200 mM NaCl reduced the shoot and the root dried biomass by 38% and 59%, respectively. The growth impairment induced by salinity was strongly correlated with an increase in the superoxide anion production (5-fold), hydrogen peroxide content (2-fold) and malondialdehyde (MDA) content (4-fold). Seedlings responded to the oxidative stress triggered by salinity with an increase in the total phenolic content (TPC), total flavonoid content (TFC) and total antioxidant activity (TAA) by 67%, 51% and 32%, respectively. A salt-induced increase in the activity of the antioxidant enzymes superoxide dismutase and catalase (CAT) of 89% and 86%, respectively, was also observed. Treatment of salt-stressed seedlings with exogenous CTS significantly promoted seedling growth, with the strongest effects observed for L-CTS and M-CTS, which increased the shoot biomass of stressed seedlings by 32% and 44%, respectively, whereas the root dried biomass increased by 87% and 64%, respectively. L-CTS and M-CTS treatments also decreased the superoxide anion production (57% and 59%, respectively), the hydrogen peroxide content (35% and 38%, respectively) and the MDA content (48% and 56%, respectively) and increased the TPC (23% and 14%, respectively), the TFC (19% and 10%, respectively), the TAA (up to 10% and 7%, respectively) and the CAT activity (29% and 20%, respectively). Overall, our findings indicate that CTS exerts its protective role against the oxidative damages induced by salinity by enhancing the antioxidant defense system. L-CTS and M-CTS were the most effective in alleviating the adverse effect of NaCl, thus demonstrating that the CTS action is strictly related to its molecular weight.
