The low fruit set is one of the main factors leading to poor yield of pear orchards in Brazil. The exogenous application of thidiazuron (TDZ) and aminoethoxyvinilglycine (AVG) has shown promising results in some pear cultivars and other temperate fruit trees. The objective of this study was to evaluate the effect of TDZ and AVG on fruit set, yield, and fruit quality of ?Hosui? and ?Packham?s Triumph? pears. The study was performed in a commercial orchard located in São Joaquim, SC. Plant material consisted of ?Hosui? and ?Packham?s Triumph? pear trees grafted on Pyrus calleryana. Treatments consisted on different rates of TDZ (0 mg L-1, 20 mg L-1, 40 mg L-1 and 60 mg L-1) sprayed at full bloom for both cultivars. An additional
treatment of AVG 60 mg L-1 was sprayed one week after full bloom in ?Hosui?. The fruit set, number of fruit per tree, yield, fruit weight, seed number, and fruit quality attributes were assessed. Fruit set and yield of both cultivars are consistently increased by TDZ, within the rates of 20 to 60 mg L-1. Besides, its application increased fruit size of ?Hosui? and did not negatively affect fruit quality attributes of both cultivars. |
