“…It has been observed, for example, that hydroponic cultures can be among the best options to increase the nutrient content of plant tissues [ 39 , 40 ]. In the case of minerals not readily translocated to the edible tissues, such as for crops grown on soil and/or for minerals with scarce mobility, another alternative is the use of foliar fertilization [ 41 ].…”

Vegetables represent pillars of good nutrition since they provide important phytochemicals such as fiber, vitamins, antioxidants, as well as minerals. Biofortification proposes a promising strategy to increase the content of specific compounds. As minerals have important functionalities in the human metabolism, the possibility of enriching fresh consumed products, such as many vegetables, adopting specific agronomic approaches, has been considered. This review discusses the most recent findings on agronomic biofortification of vegetables, aimed at increasing in the edible portions the content of important minerals, such as calcium (Ca), magnesium (Mg), iodine (I), zinc (Zn), selenium (Se), iron (Fe), copper (Cu), and silicon (Si). The focus was on selenium and iodine biofortification thus far, while for the other mineral elements, aspects related to vegetable typology, genotypes, chemical form, and application protocols are far from being well defined. Even if agronomic fortification is considered an easy to apply technique, the approach is complex considering several interactions occurring at crop level, as well as the bioavailability of different minerals for the consumer. Considering the latter, only few studies examined in a broad approach both the definition of biofortification protocols and the quantification of bioavailable fraction of the element.

“…Yang et al (2014;Ding et al, 2015) performed a comparative analysis between sorbitol alcohol and sorbitol calcium fertilizer and which concluded that both promote the absorption of nutrients by crops. However, the chelation reaction between sorbitol and inorganic salt has not been characterized, nor has there been any comparative analysis of the fertilizing effect of sorbitol chelated and sorbitol non-chelated minerals (He et al, 2019;Niu et al, 2020). The mechanism of action of sorbitol alcohol or sorbitol alcohol chelation on crops is controversial.…”

Sorbitol has the effect of promoting nutrient absorption, so it has the potential to produce excellent fertilizers. In this study, sorbitol calcium chelate was synthesized using sorbitol as the chelating agent. The effects of sorbitol calcium chelate on peanut were investigated, with the goal of promoting peanut yield and improving the utilization of calcium fertilizer. Field experiments were carried out in Jimo, Shandong Province, China. Four sorbitol calcium chelate concentrations (0.4, 0.8, 1.6 and 2.4 g L 1 ) and two sorbitol non-chelated calcium concentrations (1.6 and 2.4 g L 1 ) were tested. Compared with the corresponding sorbitol non-chelated calcium fertilizer treatments, the yield of peanuts increased by 10.0 and 1.7% under sorbitol chelated calcium concentrations of 1.6 and 2.4 g L 1 , respectively, besides, the calcium and potassium contents of the seed kernel increased by 32.2 and 55.8%, under sorbitol chelated calcium concentrations of 1.60 and 2.40 g L 1 , respectively. Sorbitol calcium chelate improved peanut yield and promoted the transformation of sugars to fat in the seed kernel, the 1.6 g L 1 concentration produced the best results. Compared with the blank control, the 1.60 g L 1 sorbitol chelated calcium fertilizer treatment increased peanut yield by 28.6%, fruit number per plant by 46.8%, 100-kernel weight by 20.4%, full fruit number per plant by 55.3%, fat content by 5.0%. In conclusion, sorbitol chelated calcium fertilizer was superior to sorbitol nonchelated calcium fertilizer under the experimental conditions used herein.

“…Treating plants with 8 or 10 mg/L Se slightly, but significantly reduced net assimilation rate of CO 2 (A N , Figure 4 A), stomatal conductance to water vapour (g SW , Figure 4 B) and ratio of intercellular to atmospheric CO 2 concentration (C i /C a, Figure 4 C), which indicates that higher selenium concentrations enhanced stomatal limitation of photosynthetic CO 2 assimilation in Stevia plants, but 6 mg/L Se treatments did not show significant effect on CO 2 assimilation and related parameters. Although the effect of exogenous Se on photosynthesis has been examined in several plant species [ 73 , 79 ], to the best of our knowledge, there is no information available in the literature about the impact of Se supplementation on the photosynthetic activity of Stevia plants. Selenium supplementation mostly enhances or does not influence photosynthesis depending on the examined plant species [ 73 ].…”

The Effect of Foliar Selenium (Se) Treatment on Growth, Photosynthesis, and Oxidative-Nitrosative Signalling of Stevia rebaudiana Leaves

Selenium (Se) enrichment of Stevia rebaudiana Bertoni can serve a dual purpose, on the one hand to increase plant biomass and stress tolerance and on the other hand to produce Se fortified plant-based food. Foliar Se spraying (0, 6, 8, 10 mg/L selenate, 14 days) of Stevia plantlets resulted in slightly decreased stevioside and rebaudioside A concentrations, and it also caused significant increment in stem elongation, leaf number, and Se content, suggesting that foliar Se supplementation can be used as a biofortifying approach. Furthermore, Se slightly limited photosynthetic CO2 assimilation (AN, gsw, Ci/Ca), but exerted no significant effect on chlorophyll, carotenoid contents and on parameters associated with photosystem II (PSII) activity (FV/FM, F0, Y(NO)), indicating that Se causes no photodamage in PSII. Further results indicate that Se is able to activate PSI-cyclic electron flow independent protection mechanisms of the photosynthetic apparatus of Stevia plants. The applied Se activated superoxide dismutase (SOD) isoenzymes (MnSOD1, FeSOD1, FeSOD2, Cu/ZnSOD1, Cu/ZnSOD2) and down-regulated NADPH oxidase suggesting the Se-induced limitation of superoxide anion levels and consequent oxidative signalling in Stevia leaves. Additionally, the decrease in S-nitrosoglutathione reductase protein abundance and the intensification of protein tyrosine nitration indicate Se-triggered nitrosative signalling. Collectively, these results suggest that Se supplementation alters Stevia shoot morphology without significantly affecting biomass yield and photosynthesis, but increasing Se content and performing antioxidant effects, which indicates that foliar application of Se may be a promising method in Stevia cultivation.
