| The aim of the present work was to evaluate the effects of auxins and gibberellins when applied at pre-harvest to the fruit development, and to the ripening and natural fall of the fruit, in 'Pêra' oranges. Trees of Citrus sinensis Osbeck cv. Pêra, 5 years old, were utilized. The treatments applied were: GA3 + 2,4-D 12.5mg L-1 of each; GA3 + 2,4-D 25mg L-1 ; GA3 + 2,4-D 37.5mg L-1; GA3 + NAA 12.5mg L-1; GA3 + NAA 25mg L-1; GA3 + NAA 37.5mg L-1; NAA + 2,4-D 12.5mg L-1; NAA + 2,4-D 25mg L-1; NAA + 2,4-D 37.5mg L-1; and water (control). The treatments were applied 3 times, at intervals of 45 days. The variables evaluated were: rate of natural fall (%), fruit length and diameter (mm), and fresh fruit weight (g). None of the treatments promoved alterations in... |

| ABSTRACT The low fruit set is one of the main factors leading to poor yield of pear orchards in Brazil. Ethylene is associated with abscission of flowers and fruitlets. Then, the application of ethylene synthesis inhibitors, such as AVG, is a potential tool to increase fruit set of pears. The objective of this study was to evaluate the effect of AVG, sprayed at different rates and timings, on fruit set, yield and fruit quality of ‘Rocha’ pear. The study was performed in a commercial orchard located in the municipality of São Joaquim, SC, during the growing seasons of 2014/2015 and 2015/2016. Plant material consisted of ‘Rocha’ pear trees grafted on quince rootstock ‘BA29’. AVG was tested at different rates (60 mg L-1 and 80 mg L-1) and timings [full... |

| El raleo de flores y frutos se utiliza para mejorar amarre, disminuir alternancia, aumentar tamaño y calidad del fruto. En mamey se desconocen la intensidad y área de la rama donde dejar los frutos para mejorar el amarre. Con base en lo anterior, se utilizaron árboles injertados de zapote mamey de ocho años en Alpoyeca e Ixcateopan Gro. Los objetivos de este estudio fueron: i), evaluar el efecto de la intensidad de raleo en la persistencia, dinámica de crecimiento y amarre final en árboles de zapote mamey. Los tratamientos fueron: dejar 1, 2, 3, 4, 5 ó 6 frutos (T1 a T6), y testigo (todos los frutos, T7). Se realizaron 17 evaluaciones, (noviembre/2011 a febrero/2013). Con los datos obtenidos se realizaron análisis de varianza, de regresión, prueba Tukey... |

| 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 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... |

| ABSTRACT The aim of this study was to evaluate the efficacy of metamitron or metamitron plus benzyladenine as a post-bloom thinner on ‘Baronesa’ and ‘Fuji’ apples. Three experiments (rate, timing and BA combination) were conducted during two crop seasons, 2013/14 and 2014/15 at the experimental station located in Caçador, SC. Fruit set, fruit drop, yield per tree, fruit size and flowering return were assessed. The efficacy of metamitron was affected by time of application, and when applied at petal fall, promoted the proper adjustment of the production load of plants. Yield per plant reduces, whereas the allocation of fruits in categories of greater size increases proportionally to the increase in the metamitron concentration applied. However, there is... |
