Abstract
Abstract Ethylene evolution was determined for tomato ( Lycopersicon esculentum Mill.) plants grown under nutrient-deficient (N, P, K, Ca, Mg, S) conditions or under full nutrition with NH 4 + or NO 3 in sand culture. Ethylene evolution increased for plants deficient in K, Ca, or Mg relative to that of plants grown on nutritionally complete solutions with NO 3 . Deficiency of N, P, or S did not stimulate ethylene evolution relative to that detected from plants grown with complete nutrition with NO 3 . Physiological stress from NH 4 + nutrition produced enhancements in ethylene evolution that exceeded those due to deficiencies of macronutrients.
