This research deals with the effects of exogenous growth regulators on mineral nutrition of the tomato plant (Lycopersicon esculentum Mill, cv. 'Miguel Pereira'). To study the influence on mineral nutrition, (2-chloroethyl) trimethilammonium chloride (CCC), at concentration of 2,000 ppm, succinic acid-2,2-dimethylhydrazide (SADH) (4,000 ppm), gibberellic acid (GA) (100 ppm), (2-chloroethyl) phosphonic acid (CEPA) (200 ppm), indole-3-acetic acid (IAA) (100 ppm), and 6-furfurylamino purine (FAP) (500 ppm) were applied. Higher levels of nitrogen, calcium and magnesium occurred in the stem of plants sprayed with CCC. Treatments with FAP. SADH and CEPA demonstrated an increase in nitrogen levels in the stem. CEPA also increased calcium contents in stems. Growth regulators used did not alter the levels of macronutrients in leaves of tomatoes in relation to check plants.
