Abstract

Abstract Succinic acid-2,2-dimethyl hydrozide (daminozide) treatment reduced both N concentration (dry wt basis) and content (mg/fruit) of ‘Mcintosh’ apple ( Malus domestica Borkh.) early in the growing season. Ca concentration was higher in treated fruits at the beginning and end of the growing season but, due to fruit wt reduction by daminozide, Ca content per fruit was not significantly different. Daminozide did not influence either concentration or content of P, K, Mg, Fe, Mn, or Zn. Concentrations of all elements examined decreased during the growing season while total content per fruit increased.
