“…The highest fruit weight was found in short pruning in the cases of both rootstocks under investigation. The positive effect of short pruning may be due to decrease in the number of buds on twigs, a fact that leads to lower competition for carbohydrates among remaining buds (Locatelli et al, 2012). Fruit with high weight in peach trees submitted to short pruning were also reported by (Kumar et al, 2010) and (Gonçalves et al, 2014).…”

Rootstocks and twig topping intensity at winter pruning for ‘Maciel’ peach three

et al. 2023

Winter pruning has been a common practice in peach. Twig topping has been associated with it, but this practice has been used at the same intensity, regardless of the cultivar. Therefore, this study aimed at evaluating productive behavior and quality of ‘Maciel’ peach grafted on ‘Capdeboscq’ and ‘Okinawa’ (P. persica) as rootstocks, when they were submitted to different twig topping intensities in winter pruning. The following three pruning intensities were evaluated: short pruning, when 2/3 of the productive twig was removed; long pruning, when 1/3 of the twig was removed; and pruning with no topping, when twigs were kept integral. Effective fructification is lower when ‘Maciel’ peach trees are submitted to short pruning, but it leads to fruit with higher weight and flesh firmness, besides larger diameters. Pruning with no twig topping and long pruning increased the fruit number and yield per tree. Not only fruit weight, diameter and soluble solid content, but also yield per tree of ‘Maciel’ peach are affected by ‘Capdeboscq’ and ‘Okinawa’, regardless of the intensity of twig topping throughout pruning. Higher concentration of soluble solids was found in peaches grafted in Okinawa. While the highest production was verified with the use of the ‘Capdeboscq’ rootstock.

“…'Charme' achieved the lowest FS in both years (7.27% in 2014 and 12.83% in 2015) due to low RRF, thus demonstrating the increased sensitivity of the cultivar to the local environment. Locatelli, Nava, Citadin, and Pichler (2012) reported that the low fruit set index and subsequent fruit yield of 'Granada' was due to the sensitivity of this cultivar to high temperatures during the flowering period and onset of the fruit set. The FS in 2015 was much greater than in 2014 due to a greater homogeneity of chill during the winter period and mild temperatures from the onset of fall; this was also found by Scariotto et al (2013).…”

ABSTRACT. The peach tree (Prunus persica) is a fruit species native to temperate climates that requires a chill during its hibernal period to overcome dormancy. However, due to genetic breeding, varieties are currently grown in subtropical and tropical regions where there are low occurrences of chill during this phenological stage. This study evaluated the adaptability and stability of the reproductive and vegetative phases of peach tree cultivars in a subtropical climate. An experiment was designed in randomized blocks with split time plots, with 23 peach tree cultivars and four replications, with each replication consisting of one plant and four shoots. The years of evaluated (plots) and the cultivars (subplots) were considered to be treatments. The relative rates of budburst (RRB), flowering (RRF), shoot formation (SF) and fruit set (FS), average time of budburst (ATB) and flowering (ATF), duration of budburst (DB) and flowering (DF) and number of hours with temperatures below 7.20°C were evaluated during the experimental period. The cultivars 'Bonão', 'Ouromel-4', 'Libra' and 'Maciel' demonstrated greater adaptability during the vegetative phase, whereas'Ouromel-4' and 'Libra' demonstrated greater adaptability and stability during the reproductive phase of peach trees in a subtropical climate.Keywords: Prunus persica, fruit set, shoot formation, chill requirement.Adaptabilidade e estabilidade de fases reprodutivas e vegetativas de pessegueiros em clima subtropical RESUMO. O pessegueiro (Prunus persica) é uma frutífera de clima temperado e necessita de frio durante o repouso hibernal para superar a dormência, entretanto, atualmente é cultivado em regiões subtropicais e tropicais, onde há menor ocorrência de frio durante essa fase fenológica. Este trabalho teve como objetivo avaliar a adaptabilidade e a estabilidade das fases vegetativa e reprodutiva de cultivares de pessegueiro em clima subtropical avaliando os estádios de brotação e floração. O delineamento utilizado foi em blocos casualizados com quatro repetições e quatro ramos por repetição, em esquema de parcelas subdivididas no tempo, no qual as parcelas representam o tempo (2 ciclos produtivos) e as subparcelas as cultivares (23). Foram avaliados a duração da brotação (DB) e floração (DF), o tempo médio de brotação (ATB) e floração (ATF), a quantidade de gemas vegetativas brotadas (RRB) e floríferas brotadas (RRF), a formação de ramos (SF) e frutificação efetiva (FS) e o número de horas com temperatura abaixo de 7,2ºC e 12ºC, e acima de 20ºC durante o período experimental. As cultivares 'Bonão', 'Ouromel-4', 'Libra' e 'Maciel' apresentam maior adaptabilidade e estabilidade da fase vegetativa e 'Ouromel-4' e 'Libra' apresentam maior adaptabilidade e estabilidade da fase reprodutiva de pessegueiro sob clima subtropical.

Peach trees are temperate climate fruit trees most planted in subtropical and tropical regions. This advance of the peach crop is mainly due to the introduction of less cold-demanding new cultivar varieties and which require using less specific techniques, such as plant growth regulators and pruning. Within this context, the objective of this work was to evaluate phenological aspects and the yield potential of the cultivars Granada, Aurora-1, Dourado-2, Douradao, Big-Aurora, Marli and Chiripá, grafted onto the "Okinawa" rootstock, planted in the region of Sao Manuel-SP, during two cultivation cycles. The experimental design used was a completely randomized design with 7 treatments and 5 replicates, with the experimental unit represented by two plants."Granada" had early harvest in mid-September, and "Chiripá" in late November and early December, in which the former was the early-ripening cultivar and the latter was the late-ripening one. "Aurora-1" and "Dourado-2", had the highest yield values, 18.95 and 16.57 t•ha −1 respectively, followed by "BigAurora" with yield values of 12.13 t•ha −1 . For subtropical regions, such as São Manuel-SP, less colddemanding cultivars are recommended, such as Aurora-1, Dourado-2 and Big-Aurora. The planting of early-and late-ripening varieties, such as Granada and Chiripá, respectively, is an interesting alternative for producers wanting to scale their production.
