“…These results are consistent with a previous study, in which NaCl, CaCl 2 , MgCl 2 and Na 2 SO 4 were found to significantly delay germination speed in M. vulgare [30]. Similarly, reductions in germination percentage and germination speed have been shown in Zygophyllum album seeds when treated with different levels (0 to 400 mM) of NaCl, CaCl 2 and Na 2 SO 4 [40]. Usually, seeds tend to maintain dormancy under salinity, which in turn contributes to reducing germination speed as well as germination percentage [41].…”

Soil salinity is a well-known abiotic factor affecting the germination and seedling growth of various plant species. Therefore, we evaluated the effects of different chloride salts (NaCl, KCl and MgCl2) and sulfate salts (Na2SO4, K2SO4 and MgSO4) on the seed germination and early seedling growth of two important ethnomedicinal shrubs of North Africa and the Mediterranean basin (Ballota hirsuta and Myrtus communis). Seeds of these species were subjected to five salinity levels (0–100 mM) and incubated at 20 °C under a light regime (12 h photoperiod). Both species demonstrated their highest germination percentage under control conditions (i.e., without salinity). However, as salinity levels increased, the germination percentages for both species decreased, regardless of the type of salt used. Cations appeared to be more determinative than the anions in regulating the seed germination of both species. M. communis seeds displayed greater sensitivity to sodium (Na+) salts, especially when accompanied with chloride (Cl−) anions. At the higher salt concentrations (75 and 100 mM), Na+ salts had a more pronounced inhibitory effect on M. communis seedling growth compared to potassium (K+) and magnesium (Mg2+) salts. Conversely, Mg2+ salts were more detrimental to seedling growth in B. hirsuta. Based on our results, it can be concluded that both of these species are able to tolerate a moderate level of salinity. Overall, B. hirsuta may be a promising choice for rehabilitating the soils dominated by chloride salts, while M. communis could be utilized for restoring sulfate-dominated soils.

“…Salinity and alkaline stress were both found to significantly inhibit seed germination, with the degree of inhibition dependent on the salinity concentration and type of salinity. The inhibitory effects of salinity stress on seed germination were primarily attributed to osmosis and ion toxicity, while alkali stress inhibited germination through higher pH values leading to ion imbalance in seeds [ 38 , 39 ]. Salt induces oxidative and osmotic stress, causing disruption of cell elongation and division [ 40 , 41 ].…”

Seed germination is a crucial stage in the life cycle of annuals in arid, saline regions and is particularly vulnerable to abiotic stresses. Peganum harmala, a valuable medicinal plant, has limited research on its seed germination response to different environmental stresses in the arid, saline regions of Central Asia. To investigate this, we studied the effects of various temperature regimes (ranging from 20/5 to 35/20 °C), light exposure (12 hours light/12 hours dark and continuous dark), seven levels of polyethylene glycol (PEG-6000) concentration (ranging from 0–30%), and four types of salinity (ranging from 0–600 mmol L−1). Our findings show that photoperiod and temperature significantly influence germination. Optimal temperature range for seed germination was observed at 30/15 °C, with simulated critical and limit values of drought tolerance being highest (17.30% and 24.98%). However, higher temperatures (35/20 °C) and lower temperatures (20/5 °C) reduced the critical and limit values of drought tolerance. Additionally, the type and concentration of salinity had a significant effect on the seed germination, shoot, and root lengths of P. harmala. Regression analysis indicated that the critical values of NaCl, Na2SO4, NaHCO3, and Na2CO3 tolerance during germination were 178 mmol L−1, 101 mmol L−1, 106 mmol L−1, and 54 mmol L−1, respectively. Salinity inhibition on seed germination followed the order: NaCl < NaHCO3 < Na2SO4 < Na2CO3. Moreover, NaCl, Na2SO4, NaHCO3, and Na2CO3 significantly inhibited the growth of P. harmala seedlings in both shoots and roots. Our study demonstrates the sensitivity of P. harmala to environmental factors such as light, temperature, drought, and salinity. The study provides valuable information on the germination ecology of P. harmala under diverse ecological scenarios, which can be useful in developing efficient propagation and utilization of this medicinal plant.

“…It is also referred to as the creosote bush, and its extensive medicinal usage dates back through the histories of both nations (Lasché et al, 2023;Schwertner-Charão et al, 2022). This plant is part of the Zygophyllaceae family, which comprises approximately 30 genera and over 250 species that are predominantly discovered in warm and arid regions (Hadjadj et al, 2022; Morales-Ubaldo, Rivero-Perez, et al, 2022). L. tridentata typically grows at heights of 0.5 to 3.5 m and produces a light perfume (Bié et al, 2023).…”

The significance of medicinal plants in inhibiting microbial growth in food and agricultural production as well as their economic viability cannot be overstated. These plants contain secondary metabolites, which are abundant in antimicrobial compounds, such as flavonoids, tannins, saponins, and alkaloids, and their extracts have demonstrated antimicrobial properties against a variety of plant pathogens. The primary objective of this study was to explore the possibility of using bioactive compounds in plant defenses and their biological applications. To achieve this, antifungal polyphenolic bioactive compounds were extracted from the stems and leaves of L. tridentata using conventional methods. The total polyphenol and antioxidant potential of the extracts were assessed and characterized using high-performance liquid chromatography (HPLC). This study compared the polyphenolic constituents of extracts from emerging maceration and Soxhlet extraction techniques in the leaves and stems of Larrea tridentata. The extracts were evaluated for total polyphenolic content (hydrolyzable (HT) and condensed tannins (CT)) and antioxidant activity (ABTS, FRAP, and DPPH). Reverse-Phase High-Performance Liquid Chromatography Electrospray Ionization coupled with mass spectrometry (RP-HPLC-ESI-MS) was used for qualitative identification of antimicrobial phytochemicals. Furthermore, the extracts were analyzed in vitro for antifungal activity against Fusarium oxysporum and Alternaria alternata. The results revealed that 60:40 ethanol:water macerated leaf extract gave the highest hydrolysable tannins (6.41 ± 0.08 mg GAE/g), while its equivalent showed the highest condensed tannins (2.81 mg CE/g). Soxhlet ethyl acetate leaf (SOX ELL) extract showed 1.14 times more condensed tannin content than that of the stems. The antioxidant potential of the extract increased with increasing polarity of the extraction solvent. SOX ELL had higher antifungal effects against F. oxysporum and A. alternata, whereas the 60:40 ethanol: water ratio resulted in 52% inhibition against A. alternata and 43% inhibition against F. oxysporum. Polyphenols with antifungal properties were found in the extracts, including caffeic acid 4-O-glucoside, rhamnetin, protocatechuic acid 4-O-glucoside, kaempferol, (+)-gallocatechin, luteolin, guteolin 7-O-(2-apiosyl-glucoside), gallic acid 4-O-glucoside, cumaric acid 4-O-glucoside, quercetin, NDGA, piceatannol 3-O-glucoside, pterostilbene, tetramethylscutellarein, and cirsimaritin. L. tridentata leaf extracts exhibit potential effectiveness in the development of biological control agents, which can not only enhance crop protection, but also contribute to overall agricultural sustainability.
