“…The cultivars used in this work were: peach: Aurora, Biuti, Bonão, Centenário, Diamante, Douradão, Libra, Régis, and Tropical; quince: Fuller, Smyruna, Portugal, Provence, Mendonza Inta-37, Alaranjado, Lageado, CTS 207, Dangers, and Bereczy; pear: Tenra, Centenária, Cascatence, Primorosa and Seleta; fig: Roxo de Valinhos, Mini Figo, Troiano, Três num Prato, Bêbara Branca, Lemon, Brunswick, and Pingo de Mel. These cultivars were chosen because they adapt to subtropical conditions (Bisi et al, 2016;Bisi et al, 2019;Coutinho et al, 2019;Tadeu et al, 2019).…”

“…The cultivation of temperate fruit trees has increased substantially, specifically in regions with a mild winter, due to the adaptability of cultivars, and results show that the production in these areas present high productivity when compared to traditionally producing temperate regions (Pio et al, 2019). Peach, pear, quince and fig trees are species that have selected cultivars with high performance in subtropical regions (Bisi et al, 2016;Bisi et al, 2019;Coutinho et al, 2019;Tadeu et al, 2019) The peach tree (Prunus persica (L.) Batsch) produces fruit with a very pleasant aroma and color that fits the list of economically important fruits, not only because of its exotic appearance, but also because it is an excellent source of bioactive compounds, (Cantín et al, 2009) like phenolic compounds (35.97 mg/100 g) and carotenoids (μg/100 g) (Legua et al, 2011). Peach is very much appreciated, mainly for having organoleptic characteristics, due to this the growing consumption of this fruit is evident (Instituto Brasileiro de Geografia e Estatística, 2020).…”

Temperate fruit species, originate from regions with cold winters and well-defined climatic seasons. These fruits are also produced in subtropical and tropical regions. The aim of this study was to determine the bioactive compounds and antioxidant activity of different fruit cultivars from fruit trees of temperate climate, such as peach, pear, quince, and fig, able to be produced in subtropic regions. Analyzes of antioxidant activity, total phenolics and ascorbic acid were carried out. In peaches, 'Biuti' had the highest phenolic content, and 'Bonão' stood out in relation of antioxidant activity (ABTS) and ascorbic acid. For quinces, 'Lageado' had higher phenolic content, 'Provence' and 'CTS' showed higher antioxidant activity (ABTS), and ' Alaranjado' stood out in relation of antioxidant activity (DPPH). 'Fuller' , 'Smyrna' and 'Portugal' are the ones with the highest levels of ascorbic acid. In pears, 'Seleta' showed the highest phenolic content, antioxidant activity (DPPH) and ascorbic acid. 'Centenaria' presented the highest antioxidant activity (ABTS). In figs, 'Três num Prato' , 'Lemon' and 'Brunswick' had the highest ascorbic acid content. 'Três num prato' and 'Roxo de Valinhos' showed the highest phenolic content and antioxidant activity consecutively. It was found that cultivars of these evaluated fruits showed great variability, even under similar conditions.

“…The interrelation of these factors and unanticipated shifts in the climate and weather patterns can influence the phenological process, leading to potential implications in the timing of dormancy release and growth resumption affecting fruit quality [1]. The phenological characterization permits us to relate variations in climate and their impacts on crops [2][3][4]. A series of phenological events that occur during an annual cycle are essential to ensuring appropriate crop management practices [5].…”

“…A period of rest known as "dormancy" with low-temperature conditions (chilling) is required for peach trees prior to resuming growth under warm temperatures after winter [2,3,9,10].…”

Phenological shifts in peaches have been observed over the last few years due to the fluctuation of the seasonal climate conditions experienced during dormancy, affecting orchard management practices and influencing production and harvest dates. This study aimed to model the vegetative and floral budbreak of selected peach cultivars. Three peach cultivars, including “Rubyprince”, “Harvester”, and “Red Globe”, were considered in this study based on the representation of the early, early-mid, and mid-seasons. The prediction of the budbreak in peaches was assessed using different models that integrate the combination of chill and heat requirements. Models used include the Weinberger model, the modified Weinberger model, Utah, the dynamic model, and the growing degree model. The accumulation of chill varies according to the season evaluated. A model that considers both chill and heat accumulation is presented for each cultivar. Budbreak as an indicator of dormancy completion was established for each cultivar. The outcome of this study is to determine the amount of chilling accumulation and thermal time required to mark the beginning of the budbreak in selected cultivars with a model that predicts the duration of the dormancy. These results are valuable information that can be used for crop management practices and support the mitigation of cold damage during this critical period of crop development.

The aim of this study was to select pear cultivars with production stability for the environmental conditions in the tropics. The design was in randomized blocks with 11 cultivars of pear, four replications and plots consisting of four plants. Between 2015 and 2019, the phenological were evaluated based on the beginning, full bloom, end and duration of flowering and harvest. The number and average fruit mass, yield per plant and estimated yield were also quantified. In the last year of evaluation, the quality of the fruits was quantified through the length and average diameter of the fruits, total titratable acidity, total soluble solids content and total soluble solids / total titratable acidity ratio. The data were submitted to the Scott-Knott grouping test and to quantify the divergence between cultivars was used the genetic distance. After detecting significant interaction between genotypes × environments, phenotypic stability of pear cultivars were analyzed by GGE Biplot methods for the estimated yield variable. The 'Tenra', 'Triunfo' and 'Seleta' cultivars are the most suitable for cultivation in regions with subtropical altitude climate. They are genetically similar, more adapted and stable, and have full or partial synchronized flowering for satisfactory productivity.
