The concentrations of iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), and cobalt (Co) in malformed and healthy panicles of mango (Mangifera indica L.), leaves and shoots bearing them were analyzed at: (i) fully swollen bud, (ii) bud inception, (iii) fully grown panicles prior to full bloom, and (iv) full bloom over three consecutive years. The concentrations of Fe, Zn, Cu, Mn, and Co varied in malformed and healthy organs at various developmental stages. Malformed panicles exhibited lower levels of Fe, Zn, Cu, and higher Mn than healthy ones. The leaves on the shoots bearing malformed panicles showed higher levels of Fe, Mn, Cu, and higher Zn than the leaves on the shoots bearing healthy panicles. The shoots bearing malformed panicles revealed higher levels of Fe, Zn, Mn, and Cu than shoots bearing malformed panicles. The levels of Co in healthy and malformed organs did not differ much. The findings of the present study, therefore, seem to point that floral malformation in mango is not caused by the deficiency of these micronutrients.
