Early performance of ‘Kampai’ and ‘Rubimel’ peach on 3 training systems

Abstract

Received: Dec. 11, 2015 -Accepted: Mar. 28, 2016 production per tree, fruit weight, yield, fruit firmness, and soluble solids. The early yield and economic return are greater in Central Leader training system for both cultivars. Besides, training system does not influence fruit quality attributes.

Performance of ‘Eragil’ peach trees grown on different training systems

“…The peaches of the LC -trained trees presented greater values in mass, diameter and fruit polar diameter in relation to the fruits from trees trained in the other systems, due to the prioritization of tree structure formation in the first year in the LC system, which has a higher source/sink relation, allowing greater growth. Mayer et al (2016) and Pasa et al (2017) found no significant changes in the fresh mass and size of peach fruit in the training systems used. However, Miller and Scorza (2002) found higher values in the fresh mass and fruit size of CL-trained trees.…”

The Fruiting Wall: An Alternative Training System for Peach Orchards in Southeast Brazil

“…Considering the Central Leader, this latter study obtained 7.77 t ha -1 and 9.57 t ha -1 (two-years old) and 14.41 t ha -1 and 11.87 t ha -1 (three-years old), respectively for 'Kampai' and 'Rubimel' cultivars (Pasa et al, 2017). However, considering the Ypsilon the yields were 4.39, 4.35, 3.27 and 5.22 t ha -1 , respectively for 'Kampai' and 'Rubimel' cultivars at two-and three-years old (Pasa et al, 2017).…”

“…These results show that despite the lower number of plants per ha, the trees from Fruiting Wall have high capability of fruit set, in addition to the highest mass per fruit. Similarly, Pasa et al (2017) present the highest values for yield by tree for the Central Leader, with 7.77 and 14.41 kg tree -1 (cv. 'Kampai'), and 9.57 and 11.87 kg tree -1 (cv.…”

“…These authors observed yields values equal to 22.2 t ha -1 (Axis) and 16.1 t ha -1 (Open Vase) for peach 'Conquise'. Pasa et al (2017) concluded that the Central Leader training system, which also has similar plant architecture to Fruiting Wall, is more productive than the Ypsilon.…”

“…Such increasement is expected to be achieved with reduced inputs (Bussi et al, 2015) and labor requirements (Caracciolo et al, 2021;Loreti & Massai, 2002). The use of high-density orchards is adopted as an option to reach these goals and induce the plants to early production (Loreti & Massai, 2002;Pasa et al, 2017;Souza et al, 2019;Uberti et al, 2020). Although this strategy is valid for increase yield, some studies have shown that it may increase root competition and the intense pruning may reduce the total carbohydrate supply (Robinson et al, 2006).…”
