“…Supplementation of the nutrients can be achieved through media modification or by foliar application [11]. Adding fertilizers in media nutrient solution helps to improve the uptake of nutrients by activating the Na/K channel through hairy roots [12]. On the other hand, foliar application allows for the rapid adsorption of essential mineral elements [13].…”

Ginseng has long been widely used for its therapeutic potential. In our current study, we investigated the impact of abiotic stress induced by infrared (IR) radiations and sodium silicate on the upregulation of antioxidant and anti-tyrosinase levels, as well as the total phenolic and total flavonoid contents of the Korean ginseng (Panax ginseng C.A. Meyer) variety Yeonpoong. The RSM-based design was used to optimize ultrasonic-assisted extraction time (1–3 h) and temperature (40–60 °C) for better anti-tyrosinase activity and improved antioxidant potential. The optimal extraction results were obtained with a one-hour extraction time, at a temperature of 40 °C, and with a 1.0 mM sodium silicate treatment. We recorded maximum anti-tyrosinase (53.69%) and antioxidant (40.39%) activities when RSM conditions were kept at 875.2 mg GAE/100 g TPC, and 3219.58 mg catechin/100 g. When 1.0 mM sodium silicate was added to the media and extracted at 40 °C for 1 h, the highest total ginsenoside content (368.09 mg/g) was recorded, with variations in individual ginsenosides. Ginsenosides Rb1, Rd, and F2 were significantly affected by extraction temperature, while Rb2 and Rc were influenced by the sodium silicate concentration. Moreover, ginsenoside F2 increased with the sodium silicate treatment, while the Rg3-S content decreased. Interestingly, higher temperatures favored greater ginsenoside diversity while sodium silicate impacted PPD-type ginsenosides. It was observed that the actual experimental values closely matched the predicted values, and this agreement was statistically significant at a 95% confidence level. Our findings suggest that the application of IR irradiation in hydroponic systems can help to improve the quality of ginseng sprouts when supplemented with sodium silicate in hydroponic media. Optimized extraction conditions using ultrasonication can be helpful in improving antioxidant and anti-tyrosinase activity.

Saffron (Crocus sativus) is the most expensive spice in the world and a valuable medicinal plant. In this study, the flowering, vegetative growth performance, and daughter corm formation of potted saffron were investigated in six growing media: loamy soil, silty soil, sandy soil, peatmoss, peatmoss + sandy soil, and peatmoss + foam. The highest values of the stigma fresh weight, the root weight, and the number and diameter of daughter corms were observed in plants grown in soil with a light texture, i.e., sandy soil or peatmoss + foam, although smaller daughter corms were produced by sandy soil-grown plants. Compared with loamy soil (heavy soil), the peatmoss + foam growing medium increased the leaf pigment levels and the number of leaves and daughter corms, and it produced the highest number of daughter corms with diameters of ≥2 cm. Compared with plants in other media, saffron plants grown in loamy soil had higher catalase and peroxidase activities but lower polyphenol oxidase activity. Overall, saffron could be cultivated and produced in growing media with various pH values (4.00–9.25), although a mixture of peatmoss and foam was the optimal growing medium for potted saffron production. These findings are beneficial for selecting the optimal growing media/soil for saffron cultivation in farmlands.
