Analysis of Essential and Toxic Microelements in Fusarium-Infected Maize and Wheat Genotypes

This study investigates the presence of essential and toxic microelements in grains of Fusarium-infected maize and wheat genotypes using ICP-MS analysis. Two maize and thirteen wheat genotypes were assessed for their microelement contents, including manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, cadmium, and lead. The study found that Fusarium infections increased microelement and toxic metal concentrations in grains. Notably, some genotypes showed higher concentrations of specific elements in different plant parts, emphasizing the importance of genotype selection for crop safety.

  1. Essential and toxic microelements in grains of Fusarium-infected maize and wheat genotypes: ICP-MS analysis Zsuzsanna Kolbert, Attila Ördög, Ágnes Vashegyi, László Erdei Two countries, one goal, joint success!

  2. Materials and methods • Plant material: • 2 maize genotypes (twosamplingtimes) • 13 wheat genotypes • Infection: • Fusariumgraminearum • Fusariumculmorum • Fusariumverticillioides • Samplepreparation: • 500 – 1000 mg fromeachsample • microwavedigestioninnitricacid and hydrogenperoxide • dilutionto 200 - 400 X • Measurement: • Microelementanalysis (Mn, Fe, Co, Ni, Cu, Zn, As, Se, Mo, Cd, Pb) by ICP-MS device Two countries, one goal, joint success!

  3. The advantages of an ICP-MS • More than 1000 samples in one week (up to 250 samples/day) • More than 15000 data from the analysis • Lot of information in a few seconds (less than a second per element) • User-friendly software (PlasmaLab), which makes the data analysis easier and faster Two countries, one goal, joint success!
