The aimed to correlate the micronutrients content in soybean seeds with their physiological potential. The work was developed in the Federal University of Pelotas, in the facilities of the Seed Science and Technology Graduate Program. The experimental design was randomized blocks in arranged in four replicates. The micronutrients measured were: B, Cu, Fe, Mn, Mo, Zn, Al and Na. The magnitudes of micronutrients are dependent on the genetic constitutions of soybean cultivars. Higher variations
