It is evident the increase in the occurrence of different stresses that impact agriculture and so there has been an increase in research to study stress mitigators including silicon (Si) and selenium (Se). However, the great challenge to be answered would be to assess whether it is possible to maximize these benefits by combining these two elements. Therefore, this review focused on discussing the feasibility of combining Se and Si in mitigating abiotic stresses and also measuring gains in yield and quality of agricultural products. These are the main challenges of plant mineral nutrition with these two elements for sustainable cultivation, ensuring food security with the possibility of improving human health. As the mode of application of an element can change absorption and assimilation processes and consequently the plant’s response, it is important to consider research with supply of these elements via the foliar and root route. Thus, we highlighted the potential of the combined application of Se and Si and whether or not they are relevant to overcome the individual application in stress mitigation or even in plants without stress. In addition, we pointed out new directions for research on this topic in order to reinforce the combined use of stress relievers and their potential benefit to crop plants.

“…Hausen (1935) reported the possibility of biofortifying Vit C in early stages of seedling growth. Only four studies (De Souza et al, 2019;Garcia Neto et al, 2021;dos Santos et al, 2022;Kathi et al, 2022) were found in the past decade that had successfully increased Vit C content in horticultural crops. of these, there were fewer studies that document how this biofortification occurs in microgreens (Kathi et al, 2022).…”

Vitamin C biofortification of broccoli microgreens and resulting effects on nutrient composition

The consumption of plants plays an important role in human health. In addition to providing macro and micronutrients, plants are the sole sources of several phytonutrients that play a major role in disease prevention. However, in modern diets, increased consumption of cheaper, processed foods with poor nutritional value over fruits and vegetables leads to insufficient consumption of essential nutrients such as vitamin C. Taking supplements can address some of the insufficient nutrients in a diet. However, supplements are not as diverse or bioavailable as the nutrients in plants. Improving the abundance of nutrients in plants will reduce the amounts that need to be consumed, thereby reducing the price barrier and use of supplements. In this study, broccoli (Brassica oleracea var. italica) microgreens grown in a controlled environment were biofortified for increased vitamin C content. The microgreens grown on growing pads were treated with supplemental nutrient solutions. Treatments were applied four to five days after germination and included four different concentrations of ascorbic acid specifically, 0% (control), 0.05%, 0.1%, 0.25% and 0.5%, added to the nutrient solution. Microgreens with turgid cotyledons and appearance of tip of first true leaves were harvested about 14 days after germination and were analyzed for biomass, chlorophylls, carotenoids, vitamin C and other minerals content. The ascorbic acid improved the microgreens’ fresh biomass, percent dry matter, chlorophylls, carotenoids, vitamin C, and potassium content. Moreover, this study also mapped out the correlation between ascorbic acid, phytochemicals, and broccoli microgreens’ mineral composition. The total vitamin C was positively correlated to K and negatively correlated to chlorophylls, N, P, Mg, Ca, S, and B (p < 0.01). These relationships can be applied in future vitamin C biofortification research across different microgreens. In conclusion, vitamin C was increased up to 222% by supplemental ascorbic acid without being detrimental to plant health and mineral composition.

“…Silicon (Si) is a bene cial element for crops, as it reduces biotic and abiotic stresses [5][6][7][8][9][10]. In addition, recent studies have reported that silicate application may increase the uptake e ciency of different crops, contributing to high nutrient concentrations in plant shoot biomass [11][12][13]. Potassium silicon application, when sprayed at a concentration of 6.3 mg Si/10 plants, increased nitrogen, phosphorus, and potassium in wheat crops under saline stress [14].…”

Purpose The benefits of applying silicon to plants under stressful conditions are recognized. However, few studies have shown the effect of supply and form of application of silicon on the nutrition of plants grown under ideal conditions. This study aimed to verify the effects of different methods of silicon application on the nutrient uptake of maize in two tropical soils.Methods Silicon was supplied in three application methods (in the planting furrow, in the total pot area, and spraying) at two rates in maize plants in two tropical soil types. Thirty days after emergence, the contents of macronutrients, micronutrients, and silicon were evaluated.Results In sandy soil, potassium silicate application contributed to an increase in N, P, K, Mg, Si, and Cu contents, whereas in clay soil, there was an increase in the plant contents of P, K, Ca, Mg, S, Cu, Si, and Mg.Conclusion It was concluded that silicon application contributed to greater nutrient uptake in maize plants. Our study suggests that silicon application could be an important tool for increasing mineral fertilization in tropical soil conditions.
