“…The moisture content of the studied 2-and 5-day old seedlings increased under most of the applied NaCl concentrations. A similar increase in moisture content of fenugreek plants at successive growth stages under salt treatment was lately recorded by Kapoor and Pande [28] who ascribed that pattern of change in moisture content to the deteriorative status of the plant cells under stress.…”

The current investigation was conducted to evaluate the potency of salinity to enhance the nutraceutical properties of fenugreek (Trigonella foenum-graecum L.) seedlings. Gradual doses of NaCl solution (0, 50, 100, 150 and 200 mM) were applied and the nutritional value of seedlings was determined 2 and 5 days' post-germination. Moreover, the antioxidant and antimicrobial activity along with the phenolic content of the considered seedlings were assessed. The obtained results manifested that salt application to different levels could increase the amount of protein, N, Zn and Cu in the 2-and 5-day old seedlings. Salinity could also raise the amount of vitamin C, B1, B2 and B9 but only in one stage. Conversely, the amount of reducing, non-reducing and total sugars as well as that of Fe declined under stress. Compared with their unsalted synonyms, water and methanolic extracts of salt-treated fenugreek seedlings had higher H2O2-scavenging activity in the two stages, while their reducing power and free radicles-scavenging activities were promoted in the second stage only. Regarding the antimicrobial activity, water and methanolic extracts of the stressed seedlings generally exhibited better antimicrobial activity against some pathogenic microbes especially Erwinia carotovora, Bacillus subtilis and Candida albicans. Only in the second stage, most of the employed salt concentrations increased the titer of tannins, saponins, alkaloids, flavonoids and total phenols in the aqueous and alcoholic extracts. Therefore, it is recommended to salinize young fenugreek seedlings to improve its health benefits in a simple, lowcost and low-risk approach.

“…The observed decrease in leaf number and FW in moderate and high salinity levels is attributed to a reduction in cell expansion due to low turgor controlled by cellular water uptake and cell-wall extension 42 . In addition, Kapoor and Pande 43 concluded that leaf numbers decreased under salinity conditions due to a reduction in branches per plant as a result of decrease in nutrient concentrations. Decline in fresh and dry weights, leaf numbers and abscissions under salinity stress were previously reported 44 .…”

considering titanium dioxide nanoparticles (tio 2 nps) role in plant growth and especially in plant tolerance against abiotic stress, a greenhouse experiment was carried out to evaluate TiO 2 NPs effects (0, 50, 100 and 200 mg L −1) on agronomic traits of Moldavian balm (Dracocephalum moldavica L.) plants grown under different salinity levels (0, 50 and 100 mM NaCl). Results demonstrated that all agronomic traits were negatively affected under all salinity levels but application of 100 mg L −1 tio 2 nps mitigated these negative effects. TiO 2 NPs application on Moldavian balm grown under salt stress conditions improved all agronomic traits and increased antioxidant enzyme activity compared with plants grown under salinity without tio 2 NP treatment. The application of TiO 2 NPs significantly lowered H 2 o 2 concentration. In addition, highest essential oil content (1.19%) was obtained in 100 mg L −1 tio 2 nptreated plants under control conditions. Comprehensive GC/MS analysis of essential oils showed that geranial, z-citral, geranyl acetate and geraniol were the dominant essential oil components. The highest amounts for geranial, geraniol and z-citral were obtained in 100 mg L −1 tio 2 np-treated plants under control conditions. In conclusion, application of 100 mg L −1 tio 2 NPs could significantly ameliorate the salinity effects in Moldavian balm. Moldavian balm (Dracocephalum moldavica L.), a perennial herb of the Lamiaceae family and native to central Asia, naturalized in central and eastern Europe and is cultivated around the world as a medicinal plant. Essential oils and extracts of Moldavian balm have been traditionally used as a painkiller for kidney complaints, toothache and colds. In addition, it has antimicrobial activities 1 , antirheumatic, antitumor, antimutagenic, antioxidant and antiseptic properties 2. Aerial parts of Moldavian balm are important sources of monoterpene glycosides, trypanocidal terpenoids, rosmarinic acid and flavonoids 3. Salinity stress is considered as one of the main environmental factors limiting plant distribution in their natural habitats 4. Soil salinity affects about 800 million hectares of arable land worldwide. Salinity stress causes major problems regarding plant growth, development and productivity, especially in arid and semi-arid regions of the world 5 manifested as changes in morphological, physiological and biochemical characteristics of plants, ion toxicity (Na + and Cl −), nutritional disorders and osmotic stress. These negative impacts significantly decrease plant

“…As indicated by the table, although the receivers were not directly exposed to the salt stress, their dry and fresh weights were still reduced compared to the controls. Salinity has been associated with lowering of both fresh and dry weights and it is inversely proportional to the salt concentration [17,18,19].…”

Plants are subjected to various types of environmental stresses throughout their lifecycle. It has been found that plants are able to communicate with the neighbouring plants under stress conditions through volatile organic compounds. These volatiles act as signals for the neighbouring plants thus preparing them for the upcoming stress, a phenomenon known as priming. So, the present study explores the effects of salt stress on cotton plants and the resultant induction of priming in the nearby plants. For this purpose, salt tolerant cotton (Gossypium hirsutum) variety was used. Two concentration levels, 100 mM, and 150 mM of salt were used to study the impacts of the stress. The experiment was divided into two steps for each treatment. In the first step, a set of plants (emitters) was given salt stress. The second set of plants (receivers) was placed adjacent to the stressed plants (emitters), while the third set of plants was placed separately as a control for both the treatments. Various physiological and morphological parameters were measured at the beginning and the end of the first step. In the second step, the receiver plants now termed as "primed" were given the same levels of stress while a new set of non-primed plants was placed near the primed plants. These non-primed plants were now treated with 100mM and 150mM of NaCl respectively and the results were compared. The results show that plants were able to get signals from neighbouring stressed plants. Plants responded by altering morphology and physiology to prepare themselves for future stress conditions.
