Effects of plant regulators on the productivity of tomato plants

Abstract

This research deals with the effects of exogenous growth regulators on fruiting of tomato plants (Lycopersicon esculentum Mill.) under greenhouse conditions. Applications of (2-chloroethyl) trimethylammonium chloride (CCC) 1,000 ppm, succinic acid-2,2-dimethylhydrazide (SADH) 2,000 ppm, 3-chlorophenoxy propionic acid (3 -CP) 50 ppm, thiazolidin-4-carboxylic acid plus folic acid 0,75 ml/l, and water (check treatment) were performed. It was observed that SADH reduced total weight, number and weight average of tomato fruits, because of flower abscission caused by the timing of the repeated application. Thiazolidin-4-carboxylic acid plus folic acid reduced the total weight and weight average of tomato fruits. Application of 3-CP showed a tendency to increase total weight and number of fruits in the plant.
