Is fruit dry matter concentration a useful predictor of 'Honeycrisp' apple fruit quality after storage? Repositório Alice
ROBINSON, T. L.; RUFATO, A. de R.; RUFATO, L.; DOMINGUEZ, L. I..
In climates such as New York State, USA, fruit quality (taste and bitter pit incidence) of "Honeycrisp" apple varies significantly from year to year. Our research with Honeycrisp? indicates that when crop load is too high the tree cannot supply sufficient carbon, and other nutrients to give optimum fruit quality (taste, appearance and storageability). Similarly if weather patterns are cloudy, tree carbon acquisition is reduced and carbon supply for fruit growth is limited resulting in less than adequate resources for optimum fruit quality. In an attempt to predict "Honeycrisp' eating quality and bitter pit incidence post storage we began a study in 2013 where we measured fruit quality characteristics at harvest of 30 orchards in western NY and 20 orchards...

Vigor control in ?McIntosh? apple trees by growth inhibitors. Repositório Alice
RUFATO, L.; BRIGHENTI, A. F.; RUFATO, A. de R.; DOMINGUEZ, L. I.; ROBINSON, T. L..
Abstract We evaluated the effects of two gibberellin biosynthesis inhibitors [Prohexadione-Ca (Apogee ® 250 ppm) and Trinexapac-ethyl (Moddus ® 225 ppm)], on shoot growth of mature ?McIntosh?/M.9 apple trees. The growth regulators were applied 7 days after bloom, when shoots were 5 cm long. Shoot length was measured every 15 days to determine growth rate. Shoots were measured in the lower, middle and upper portion of tree and according type (terminal and lateral shoots). The number of fruits tree -1 , yield and yield efficiency were determined at harvest. After harvest, fruits were classified according to the color. Both growth inhibitors reduced shoot growth rate approximately 30% and reduced the daily growth rate (cm day -1 ) of all types of shoots and...
