Thidiazuron (TDZ) increases fruit set and yield of ‘Hosui’ and ‘Packham’s Triumph’ pear trees

ABSTRACT 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 P...
