Medicinal plants have been used to cure human diseases since decades. Silybum marianum, a medicinal plant, is regarded as a source of secondary metabolites with therapeutic value against liver diseases and diabetes. The present study was conducted to enrich the production of secondary metabolites in the vegetative parts of Silybum marianum using elicitation strategy in hydroponic system with different elicitors. The elicitors of fungus Aspergillus niger (0.2 g/L), methyl jasmonate (MeJA) (100 μM) and silver nanoparticles (AgNPs) (1 ppm) were added in hydroponic medium, individually and in combination form to the 15 days old plant. The elicitor-treated plants were harvested at different time points (24–144 h; increment 24 h) and their biochemical parameters like phenolics, flavonoids, nitric oxide (NO), and superoxide dismutase (SOD) were analyzed. The results showed hyper-accumulation of these biochemical contents, especially in response to MeJA (100 μM), followed by AgNPs (1 ppm) and co-treatment of AgNPs (1 ppm) with other elicitors. The results revealed that the treatment with MeJA (100 μM) exhibited the highest flavonoid (304 μg g–1), phenolic (372 μg g–1), and SOD (16.2 U g–1) contents. For NO levels, the maximum value of 198.6 nmole g–1 was achieved in response to the treatment with MeJA + Green synthesized AgNPs (100 μM + 1 ppm). Our findings depicted an enhanced production of medicinally important plant secondary metabolites and antioxidants; hence, the method applied in this study can play a significant role to improve therapeutic values of the plants.

“…However, foliar Al concentrations of 'Brigitta' were 2.6 times higher than 'Brightwell' (Table 2). High Al level in blueberry leaves could reduce photosynthesis electron transport at PSI level, and decline photosynthesis rate, therefore, influence blueberry growth (Ulloa-Inostroza, et al, 2019). In the study, similar results were found on 'Brigitta' (Table 3).…”

Aluminum (Al) is the major factor limiting plant growth on acidic soils. Blueberry (Vaccinum spp.) is an acidophilic plant. Highbush blueberry and rabbiteye blueberry are the main commercially cultivated species, while the response of which to Al is still unclear. Therefore, hydroponic experiments were conducted to determine the effect of Al (0 and 100 μmol L−1) on the growth and nutrient uptake of highbush blueberry ‘Brigitta’ and rabbiteye blueberry ‘Brightwell’. The results showed that root biomass, root length per fresh weight, root activity and foliar nitrogen (N) concentration of ‘Brigitta’ were significantly decreased by Al, while root lipid peroxidation was increased by Al. In contrast, the biomass and root activity of ‘Brightwell’ were not affected by Al treatment, root lipid peroxidation was significantly decreased, root length and surface area per fresh weight were increased compared with the control, which was benefic for nutrients absorption. In fact, foliar N concentration of ‘Brightwell’ was increased in Al treatments. However, fewer Al was accumulated in leaves of ‘Brightwell’ compared to ‘Brigitta’. Therefore, it could be concluded that growth and nutrients uptake of ‘Brightwell’ was not negative affected by Al, which meant ‘Brightwell’ was resistant to Al, compared to ‘Brigitta’.

“…Damage to the growth and development of plants exposed to Al is associated with oxidative damages in the membrane lipids, generally related to the increased content of hydrogen peroxide (H 2 O 2 ) (Pandey et al 2016;Ulloa-Inostroza et al 2019). Chen et al (2012) have assessed the effects of Al on Vicia faba and found that H 2 O 2 content in the roots of cultivar Anhui Candou increased by 2.3 times that of the control, after 24 h of exposure to Al.…”

Aluminum (Al) toxicity is one of the main aspects restricting the development of fabaceous plants grown in soils with spontaneous vegetation prevalence in temperate climate zones. Salicylic acid (SA) minimizes the effects of stress on plants. Therefore, the aim of the current study was to evaluate the ability of SA seed priming to mitigate the effects of Al on seed germination and seedling performance in two Trifolium species. Trifolium vesiculosum (annual) and Trifolium repens (perennial) seeds were primed in solution added, or not, with SA (25 μM) and placed on germination paper moistened with aluminum sulfate (Al 2 (SO 4) 3) solutions at three different doses: 0 mM (control), 0.25 mM (moderate dose), and 1.25 mM (high dose). Seed priming with SA has mitigated the global toxicity effects of Al on T. vesiculosum and T. repens seedlings. Inferior damages were observed in T. vesiculosum root length and dry mass and in T. repens shoot dry mass, after SA pretreatment. T. vesiculosum seed priming with SA in the presence of Al has significantly reduced the osmotic potential of seedling sap. Salicylic acid (SA) has also enabled increased antioxidant activity of enzymes such as superoxide dismutase (SOD) in the two investigated plant species and ascorbate peroxidase (APX) in T. repens. In addition to the increased antioxidant activity, SA-primed seeds reduced the malondialdehyde content in T. vesiculosum seedlings exposed to Al. Overall, seed priming with SA mitigates oxidative effects of Al and improves T. vesiculosum and T. repens seedling performance in the presence of this element.
