Abstract

The uptake of micronutrients (B, Cu, Fe, Mn and Zn) by the variety IAC-25 in various phases of its development was studied, the plants being grown in nutrient solution, Main conclusions were the following: (a) only two variables, namely dry matter production an Fe accumulation, showed a tendency to level off as the plants complete their life cycle; (b) indication of internal redistribution was observed in the case of Fe and Mn; (c) maximum rate of uptake, was well as of dry matter production took place in the period which goes from tillering to grain filling.
