Contenido: | Abstract. The aim of this study was to evaluate the effect of different aminoethoxyviniglycine (AVG), thidiazuron (TDZ) and prohexadione calcium (P-Ca) rates sprayed at different timing on fruit set, yield, and fruit quality of 'Rocha' pear trees in different climatic conditions of Sothern Brazil. The study was performed in two commercial orchards located in Sao Joaquim, SC, (2015/2016) and Antonio Prado, RS (2016/2017). Plant material consisted of 'Rocha' pear trees grafted onto Pyrus calleryana and quince roorstock 'BA29' in Sao Joaquim and Antonio Prado, respectively. Treatments consisted of AVG, TDZ and P-Ca sprayed at different rates and timins. Truk cross-sectional area increase, fuit set, thinned fruit length, fruit diameter, L/D ratio, seed number, flesh fimmess, and soluble solids content were assessed. Fruit set and yield were consistently increased by AVG in all experiments. Fruit set was not affected by P-Ca 100 mg L-1 Sprayed at full bloom + 7 days after full bloom and TDZ 10mg-1 at full bloom. Fruit size was consistently incrased by TDZ.
