“…To minimize the effect of the soil-Se interaction, in the present research, a foliar application of sodium selenate was practiced using similar concentrations (50 mg L −1 ) for all the botanical varieties examined. Previous investigations demonstrated that this concentration did not demonstrate significant effects on plant growth in some cases [10] but was beneficial to kohlrabi [7,28], broccoli [11,29], and cauliflower [30][31][32].…”

The relationships of selenium (Se) with other elements in plants is important for producing functional food with high Se contents and a predicted quality. To unveil the peculiarities of the element interactions, eight botanical varieties of Brassica oleracea L. were grown in similar conditions with or without foliar application of sodium selenate. High varietal differences, elicited by the Se supply, were recorded with regard to the accumulation of the elements examined, except for Mg, P and Si. Cabbage florets (broccoli and cauliflower) were characterized by both the lowest total mineral content and number of elements showing content changes under the Se supply (7–8 out of 25), whereas in Savoy cabbage, the highest number of minerals displayed content changes (13–14 from 25). The Se treatment did not significantly interfere with the high correlation coefficients recorded between Sr–Ca, Co–Ni and Zn–Mg (0.824–0.952). The selenium biofortification value varied from 12 to 138 depending on the species and was inversely correlated with the Si accumulation in the control plants (r = −0.872, p < 0.001). A significant decrease in the correlation coefficients occurred due to the Se supply regarding Zn with P and Co, Ca with Co and Li, Li and V, and Na and Sn, while the V–Pb relationship was significantly enhanced. Among the 25 elements studied, Cr demonstrated the highest number of significant correlation coefficient changes (with K, Na, P, Si, Zn, Cu, Co, I, As, Pb, and V). The results of this research prove the variability of the element interactions under foliar Se treatments in Brassica oleracea plants and reveal, for the first time, an inverse correlation between the Se biofortification level and Si content in untreated plants.

“…The beneficial effect of low Se doses on plant growth and development was previously described for many plant species including representatives of the Brassicaceae and Amaryllidaceae families [ 9 , 18 , 23 ]. In the case of ramson and horseradish joint cultivation, Se supplementation improved the growth of both plants.…”

“…Taking into account that both Allium and cruciferous vegetables are regarded as Se accumulators tolerant to Se supplementation [ 18 , 23 , 30 ], it should be highlighted that, while Se biofortification of wild ramson has been investigated previously [ 9 ], so far, no attempts have been made on the production of A. rusticana roots fortified with Se, though this approach for human Se status optimization is highly valuable as horseradish roots are a well-known spice with significant antioxidant activity and high medicinal value [ 31 ].…”

Despite the high value of ramson (Allium ursinum) in medicine and nutrition, it is not cultivated in open fields due to the need for shading as well as weeding during the early crop stages. Research was carried out in an open field with the aim to improve A. ursinum growth, through its intercropping with Armoracia rusticana (horseradish). In the latter context, with and without sodium selenate application, ramson and horseradish showed reciprocal growth stimulation, as ramson biomass increased by 1.28 times and horseradish root biomass by 1.7 times. The biofortification level of horseradish roots increased from 5.9 to 9.6 times due to joint plant growth under selenium (Se) supply. The opposite phenomenon was recorded for ramson leaves, as the biofortification level decreased from 11.7 in the case of Se supplementation to 6.7 in plants supplied with sodium selenate when jointly cultivated with horseradish. Among the tested antioxidants, the highest increase due to joint cultivation and/or Se supply was recorded for ascorbic acid by 1.69 times in ramson leaves and 1.48 and 1.37 times in horseradish roots and leaves, respectively. All treatments significantly increased the total antioxidant activity (AOA) of horseradish leaves (by 1.33–1.49 times) but not roots. Comparison of the results obtained in field conditions with those obtained earlier for the Se biofortification of ramson in the natural habitat (forest) revealed significantly higher levels of the plant’s antioxidant status under environmental stress (field) and a decrease in the correspondent differences as a consequence of Se biofortification. The estimation of allelopathic beneficial interaction between ramson and horseradish implies the efficiency of ramson growth and production of functional food with high levels of Se (Se–ramson leaves and Se–horseradish roots).
