Effect of Foliar Application of Sodium Selenate on Mineral Relationships in Brassicaceae Crops

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