Abstract

This study had the following objectives: to induce and describe symptoms of deficiency of boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo) and zinc (Zn), determining the effect on the mineral composition of leaves. The experiment was developed in a green house and used diagnosis technique by subtraction. The experimental design usedn was a randomized blocks, with seven treatments and three replicates. It was verified that micronutrient omission led to morphological alterations which, in turn, caused visual symptoms. The symptoms caused by the omission of Cu, Mn and Zn were the first to appear, and were followed by those of B, Fe and Mo. The omission of B, Mn and Zn was responsible for the more pronounced reduction in height and stem diameter.
