Resumo
The present experiment was conducted in a commercial tangor 'Murcote' citrus grove in Pratania, São Paulo State, Brazil and had the objective to evaluate the effects of, 2,4-D (auxin), NAA (auxin), GA(3) (gibberellin) and BA (cytokinin), on the reduction of seed number, without modifications on citrus fruit quality. The treatments sprayed were as follow: control (water); 10 and 20 mg.L-1 of 2,4-D; 100, 150 and 200 mg.L-1 of NAA; 100 and 200 mg.L-1 of GA(3) ; 20 and 40 mg.L-1 of BA. The results showed that none of plant growth regulators influenced fruit quality, without weight reduction, diameter or (0)Brix. In relation to seed number, none of the plant growth regulators were effective on reduction of seed number, however the reduced of viable seed number and total seed number of fruits, specially with the treatment of 100 and 200 mg.L-1 of NAA and 100 mg.L-1 of GA(3), that showed a reduction of 30% of total seed of tangor murcott fruits.
