Minor content of B was registered in in-florescences than in leaves, and an apical dominance by this element was observed. Differences between B content on leaves and inflorescences were not found either north and south sides of the canopy or between autumn and winter inflorescences. The results suggest an homogeneous distribution of B in the plant through the time
