“…In a recent study evaluating open vase (571 trees ha −1 ), Y-shaped (1333 trees ha −1 ) and central leader (2500 trees ha −1 ) systems in Brazil, it was demonstrated that the central leader maintained the smallest canopy volume (m 3 ), yielded the least number of fruits per tree, but given the higher planting density, produced the most on a per hectare basis (Mt ha −1 ) [61]. A similar trial revealed that after four years, a V-system (i.e., Tatura trellis, Y-shaped) yielded the most on a cumulative basis (1388 trees ha −1 , 80.1 Mt ha −1 ), followed by a central leader/spindle (1388 trees ha −1 , 66.1 Mt ha −1 ) and then a bush system (i.e., open vase) (606 trees ha −1 , 47.7 Mt ha −1 ) [62].…”

Peach production in the USA has been in decline in recent decades due to poor fruit quality, reduced consumption and increased cost of production. Productivity and fruit quality can only be enhanced in the orchard through optimizing preharvest factors such as orchard design and training systems. Transition from low-density plantings (LDP) to high-density plantings (HDP) in peach is associated with the availability of reliable size controlling rootstocks. Increased densities must be combined with modern training systems to diffuse vigor and further increase light interception and yields, while optimizing light distribution, fruit quality and cost of production. Several training systems have been tested in peach with various objectives and goals, such as increasing light, water use and labor efficiencies, along with designing canopy architectures to facilitate mechanization and robotics. In general, increased planting densities increase yields, but excessive densities can promote shade, while excessive crop load can deteriorate quality. An ideal peach cropping system should optimize light interception and light distribution to balance maximum yield potential with maximum fruit quality potential. Successful management of high-density peach fruiting wall systems can lead to enhanced and uniform fruit quality, and ensure a sustainable industry.

Rootstock contributes to increase the absorption and nutrients translocation efficiency. We aimed to select rootstocks according to the nutritional physiological state of the scion cultivar. The experiment was carried out during three periods of leaf collect on the 4-year old peach cv. BRS Libra budded onto 21 rootstocks cultivated in a high density orchard. The following traits were evaluated: xylem water potential, dry leaf mass and chemical leaf nutritional analysis. The collected data were submitted to analysis of variance by the F test and some genetic parameters were estimated. When significant, the means were compared using the Scott-Knott test, at 5% significance. The principal component analysis was performed to verify the interrelationships between the rootstocks and the evaluated traits. The deviation from optimum percentage index was used to select the most nutritional stable rootstock. We observed that rootstock affects the dynamic absorption nutrient parameters in interactions with the scion. The highest foliar levels of P were found in the BRS Libra cultivar when budded onto the rootstocks ʹSanta Rosaʹ, ʹBarrierʹ, ʹTsukuba-1ʹ and ʹRosaflorʹ. The leaf analysis revealed a high variation in the mineral nutritional status among the studied Prunus rootstocks. Most of the mineral macro-elements varied between medium and optimal levels. The rootstocks ʹRigitanoʹ and ʹNemaredʹ showed less nutritional limitation and is recommended for cultivations in high density orchards.

“…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).…”

“…However, invasive summer pruning, which are often required in warmer climates, may significantly decrease the orchards long-term profitability (Loreti & Massai, 2002). In addition, the influence of plant architecture on stone fruits yields, such as peach and nectarine, under tropical and subtropical conditions is still poorly know (Afonso et al, 2017;Lal et al, 2017;Uberti et al, 2020).…”

The choice of the training system is a key step to the establishment of new orchards since it affects yield and fruit quality. In this context, the aim of this study was to evaluate the performance of the scion cv. Tropic Beauty in the Fruiting Wall training system compared with the Y-Shaped. The two training systems showed no statistical differences among the years regarding the length of phenological cycles (approximately 140 days). The Fruiting Wall showed higher values for yield per tree (from 80.2 to 112.9%), fruit weight (from 7.6 to 10.3%) and fruit pulp from 9.4 to 12.6%) than Y-Shaped. The mean values for flesh firmness and fruit chemical characteristics ranged over the years for both training systems. Despite the lack of significant differences for fruit chemical characteristics, the observed values were compatible with those expected for the cultivar. Data collected from the Fruiting Wall showed lower variance than those collected from Y-shape. This suggests that the Fruiting Wall leads to a higher uniformity of production and fruit quality than the Y-Shaped. Based on these results, we concluded that the Fruiting Wall improves the peach cv. Tropic Beauty production, particularly for yield by tree and fruit mass.
