| Abstract:
The Brazilian peach industry has increased over the last 3 years. High-density systems for growing peach trees are techniques that are becoming extensively utilized, but how peach trees respond to these types of training management is unknown under Brazilian conditions. The objective of this study was to evaluate the vegetative and reproductive responses of 2 training systems in an ICM (Integrated Crop Management) peach orchard. The study was carried out at the experimental farm of the University of Pelotas, Brazil, in a 4-year-old peach orchard of cv. ‘Maciel’ on Capdebosq rootstock, spaced at 1,5 x 5,0 m apart, in a completely randomized block design with three replications. The effect of Y and Central leader training systems on fruit yield, frequency of buds, trunk diameter, canopy size and fruit quality (diameter, weight, flesh consistence and acidity) and damage percentage of Xanthomonas arboricola pv Pruni, Monilinia fruticola, Grapholita molesta, Anastrepha fraterculus and birds was evaluated. The Y system had smaller trunk diameters; fruit yield (2,61 ton/ha) and canopy size but better quality of fruits when compared with the Central leader, which had a fruit yield of 8,55 ton/ha. A higher percentage of damage from M. fruticola was observed in the Central leader system. | |
