Chemical thinning is a practice performed to increase fruit size and <br>nutritional value with benefits for growers and consumers. By using ethephon and benzyladenine at 0, 150, 300 and 450 mg L-1, fruit <br>thinning in red guava was evaluated. The percentage of fruit setting and increase in fruit mass, marketable yield, soluble solids (SS), <br>titratable acidity (TA), SS/TA ratio, pH, sugars, ascorbic acid, antioxidant activity, total phenolic compounds, flavonoids and pigments <br>were evaluated. The plant growth regulators improved the setting of larger fruits. Fruit thinning higher efficiency was observed in the <br>ethefhon and benzyladenine concentrations from 300 mg L-1 and upwards, however, benzyladenine induced phytotoxicity at the same <br>concentrations. The chemical thinning can be used to promote larger fruits with better uniformity favoring higher marketability and as a <br>source of interest compounds enhancing nutritional guava fruits value depending on the thinner and the concentration</p>}, number={2}, journal={Emirates Journal of Food and Agriculture}, author={de Souza Silva, Marcelo and Leonel, Sarita and Leonel, Magali and Mirellys Azevedo Souza, Jackson and Bibiano Ferreira, Rafael and Calsavara Martins, Rafaelly}, year={2022}, month={Mar.} }
