The residues of ethephon were determined in onions during their storage after previous treatment of onion plants with Ethrel. The onion varieties Wolska and Czerniakowska were used. The levels of these residues during 5 years of determinations ranged from 0.07 to 1.45 mcg/kg of fresh mass. The level of etefon residues was higher in onions treated with Ethrel later. No evident relationship was noted between these varieties or the concentration of Ethrel in the used range on the result of residue determination.
