M.  aConcentration of chromium, nickel, and vanadium in plant materials.h[electronic resource]  c1975  aBy adding V and Ni to the culture nutrient solution the V and Ni concentrations in the plants investigated were increased substantially. Vanadium had no particular affinity for natural biogenic fats and oils, nor was it found in high concentration in commercial vegetable oils. The concentrations of Cr, Ni, and V in wheat seed indicate that the concentrations of these elements are influenced by geochemical factors; thus, it should be possible to map areas where plant seeds would contain different amounts of these elements.  aBioquímica  aNutrição mineral  aPlant materials  aPlantas1 aCARY, E.
