Abstract One-year-old transplants of ‘Olinda Valencia orange’, ‘Murcott Tangerine’, and ‘Limoneira 8A Lisbon’ genotypes were grafted on ‘Macrophylla’ rootstock and subjected, along with ‘Macrophylla’ rootstock, to 24 h of the night chilling (nocturnal) at 20/4 °C±1 (day/night) for three days, (8 h per day), followed by three days of recovery at 30/25 °C±1 (day/night). The results showed that leaf diffusion resistance (LDR), proline, malondialdehyde (MDA), peroxidase (POX), and superoxide dismutase (SOD) increased significantly in all genotypes, while there was a significant decrease in photosynthetic apparatus, polyphenol oxidase (PPO), and catalase (CAT) under nocturnal chilling stress. Under the chilling, Macrophylla rootstock had the highest concentrations of proline and SOD, whereas it had the lowest MDA and total chlorophyll concentrations. Noticeably, the enzymatic antioxidant profiles were enhanced after being recovered. Moreover, ‘Murcott’ had the highest LDR, MDA concentration, thickness of lamina, midvein, palisade tissue, spongy tissue, and dimension of midvein vascular bundle. Meanwhile, it had the lowest stomatal conductance (GS) and transpiration rate (E). Similar results were obtained with ‘Valencia’ genotype. In contrast, the ‘Limoneira 8A’ genotype under the chilling had the lowest levels of LDR, antioxidant enzymes (POX, CAT, and PPO), thickness of lamina, midvein, palisade tissue, spongy tissue, and dimension of midvein vascular bundle.

Abstract The evaluation of new banana genotypes with agronomic potential and tolerant to the main pests and diseases is essential for the market. The objective was to evaluate the vegetative and productive characteristics of new potential banana clones, such as ‘Prata Gorutuba R1’ and ‘Prata Gorutuba R2’ and commercial cultivars. The experiment was implemented in a rural property located in the municipality of Nova Porteirinha, MG. The treatments consisted of ‘Prata Gorutuba R1’ and ‘Prata Gorutuba R2’ banana clones (genotypes selected from the ‘Prata Anã’ clone ‘Gorutuba’ tolerant to Panama disease) and four cultivars: ‘Prata Gorutuba’, ‘Prata Anã’, ‘Grande Naine’ and ‘BRS Princesa’. The treatments were distributed in randomized blocks, with four replications and six useful plants per plot. The planting spacing used was 3.5 m x 1.7 m. The evaluations were carried out in the first and second production cycles. The ‘Prata Gorutuba R1’ and’ Prata Gorutuba R2’ clones in general showed excellent performance compared to the already consolidated cultivars. The clones presented median height and number of leaves in the ideal flowering for banana trees of the ‘Prata’ subgroup. Bunch and bunch weight, as well as production were similar to the ‘Prata Anã’, ‘Prata Gorutuba’ and ‘BRS Princesa’ cultivars. Considering that the clones evaluated present high tolerance to Fusarium wilt, the result indicates that the materials have great potential for the registration of new cultivars.

Abstract This study was carried aiming to evaluate different hydrogen cyanamide concentrations (0.00%; 0.26%; 0.52% 0.78% and 1.04%) associated with (3%) mineral oil on the bud growth of the ‘Eva’ apple tree in a high-altitude tropical climate region in the state of Minas Gerais. Sprouting percentage, fruit set: ratio between number of fruits and number of flowers (%), number of fruits per plant and flowering phenology were evaluated during the 2020 and 2021 production cycles. Even not being submitted to temperatures below 7.2°C, the ‘Eva ‘ cultivar completed its production cycle in two subsequent years. Hydrogen cyanamide application combined with mineral oil promoted increased budbreak and flowering uniformity, in addition to anticipating the beginning of flowering of the ‘Eva’ apple cultivar.

Abstract Avocado is an important fruit for fresh consumption and as raw material for several industries. In order to obtain good productivity and fruit quality, adequate plant nutrition is essential. However, information on the relationship between time of year, phenology and nutritional status of plants of different genotypes is difficult to compare, as most data are obtained from plants of different ages, planted in soils with different fertility levels, different management strategies and most cultivated under edaphoclimatic conditions different from those of Brazil. This study evaluated the seasonal nutrient content variation of avocado leaves, genotypic differences, the relationship with phenological stages and the periods of greater nutrient content stability in ‘Fortuna’, ‘Geada’ and ‘Quintal’ avocado genotypes cultivated in the municipality of Jardinópolis-SP, Brazil. All plants aged 30 years, were randomly planted within the same area and submitted to the same cultural treatments and management. Nutrient contents are more stable during the flowering phase (July to September) and in the final phase of fruit formation (February to March). In most of the cycle, ‘Geada’ plants have lower S, P and Zn levels compared to ‘Fortuna’ and ‘Quintal’ genotypes. ‘Fortuna’ genotype has higher Ca, Mg and Mn levels than the others at the time of fruit harvest (April to June). In the budding phase of the three genotypes (October), increase in N, P, K, S, Cu, Zn contents and decrease in Ca, Mg and Mn contents were observed.

Abstract Blackberry fruits belong to the genus Rubus, are fruits more cultivated in temperate climate in the summer, with low luminosity and low temperature in the winter. These fruits have as characteristic the quickperishingafter harvest and regression models, more specifically, nonlinear models, single or double sigmoid growth curve, are more recommended to model the growth of living beings. Several authors have used these models, considering only the average data of individuals under study; however, they do not consider the variability between them. One way to better capture the variability between individuals is by using mixed-effects nonlinear models that, by definition, combine the fixed and random part in the same model. Data used in this work were diameter and length of ‘Choctaw’ blackberry fruits, . The random effects of models were tested on parameters, with some steps, in order to reach the most appropriate model. For fixed-effects models, the least squares method was used, and for mixed models, the restricted likelihood was used. To reach the model that best fits data, the fit quality criteria (R2, AIC c and TRV) were used. For fruit diameter, the simple sigmoid nonlinear model was the logistic with random effect in ß1 and ß2, and for fruit length, the model was the Logistic + Logistic, with random effect in ß1 and ß4.

Abstract “mora de Castilla” is a native shrub of the Andean tropics and can be found in Colombia, Ecuador, Mexico, and other countries of this region. In Colombia, this fruit is cultivated by small producers and is an important source of income and rural employment. “mora de Castilla” is in great demand for domestic consumption as well as for export because it can be consumed fresh or processed and because of its extraordinary organoleptic and nutritional attributes. Risaralda is one of the departments in which Rubus glaucus Benth. is cultivated; there, plants with and without prickles are widely distributed. Although some studies have been carried out on these cultivars, it is necessary to evaluate and compare some of their attributes as an approach to recognize potential uses in agribusiness. Therefore, a physicochemical characterization was performed, the vitamin C content was evaluated, the amount and profile of anthocyanins were determined, and the antioxidant capacity of fruits of “mora de Castilla” with and without prickles was analyzed. The physicochemical parameters evaluated were weight, pH, soluble solids and titratable acidity. The content of vitamin C was evaluated using the 2-nitroaniline spectrophotometric method, and anthocyanins were evaluated using 2 methods: spectrophotometry (pH differential) and chromatography (HPLC). Finally, the antioxidant capacity was determined using the FRAP and DPPH methods. Significant differences were found between the municipalities as well as between the materials with and without prickles with regard to antioxidant capacity and vitamin C and anthocyanin content, with the highest values for fruits grown in the municipality of Pereira, Risaralda. The results obtained indicate that “mora de Castilla” with and without prickles is a fruit of high quality and promise because of its high content of bioactive compounds (vitamin C and anthocyanins), its relevant function as an antioxidant and its valuable organoleptic attributes.
“卡斯蒂亚莫拉”是安第斯热带地区的一种原生灌木，在哥伦比亚、厄瓜多尔、墨西哥和该地区的其他国家都有发现。在哥伦比亚，这种水果由小生产者种植，是收入和农村就业的重要来源。“mora de Castilla”在国内和出口都有很大的需求，因为它可以新鲜或加工食用，因为它具有非凡的感官和营养特性。Risaralda是Rubus glaucus Benth的部门之一。是培养;在那里，有刺和没有刺的植物广泛分布。虽然对这些品种进行了一些研究，但有必要对它们的一些特性进行评价和比较，以确定它们在农业综合企业中的潜在用途。为此，本文对仙人掌果实进行了理化表征、维生素C含量测定、花青素含量测定和抗氧化能力分析。评估的理化参数包括重量、pH、可溶性固形物和可滴定酸度。采用2-硝基苯胺分光光度法测定维生素C含量，采用分光光度法(pH差法)和色谱法(HPLC法)测定花青素含量。最后，采用FRAP和DPPH法测定其抗氧化能力。在不同的城市之间，以及有刺和没有刺的材料之间，在抗氧化能力、维生素C和花青素含量方面存在显著差异，在佩雷拉、里萨拉尔达市种植的水果的价值最高。结果表明，带皮和不带皮的“卡西提亚”因其高含量的生物活性化合物(维生素C和花青素)、抗氧化剂的相关功能和宝贵的感官属性，是一种高品质和有前途的水果。

Abstract The study was aimed to assess the effects of exposure of the “Benihoppe” strawberry (Fragaria×ananassa Duch.) to La3+ treatment during propagation and rooting in vitro. The results showed that propagation and rooting were inhibited by lower (0.2, 0.5 mg/L) and higher (40.0 mg/L) concentrations of La3+, respectively. Propagation and rooting were promoted by a moderate concentration (1.0, 10.0, and 15.0 mg/L) of La3+, and a concentration of 1.0 mg/L was found to be optimal. Under 1.0 mg/L of La3+ treatment, certain trends associated with changes in the levels of hormones and 12 nutrients, with the exception of Ca, were observed during plant growth in vitro, and a greater balance was observed in the trends associated with changes in the amounts of elements at the rooting stage, as compared to the propagation stage. Furthermore, the elements or hormones with the highest effects on the two stages of propagation were Co and K (positive), and TDZ and Fe (negative), while those that affected the two stages of rooting were S and Zn ( positive), and IAA and Fe (positive). Our findings suggest that the use of 1.0 mg/L of La3+ is cost-effective, and can help achieve strawberry propagation and rooting in vitro.

The results showed that propagation and rooting were inhibited by lower (0.2, 0.5 mg/L) and higher (40.0 mg/L) concentrations of La3+, respectively. Propagation and rooting were promoted by a moderate concentration (1.0, 10.0, and 15.0 mg/L) of La3+, and a concentration of 1.0 mg/L was found to be optimal. Under 1.0 mg/L of La3+ treatment, certain trends associated with changes in the levels of hormones and 12 nutrients, with the exception of Ca, were observed during plant growth in vitro, and a greater balance was observed in the trends associated with changes in the amounts of elements at the rooting stage, as compared to the propagation stage.

Abstract Grapes are not considered a good host for the spotted-wing drosophila, Drosophila suzukiiHowever, its damage results in qualitative and quantitative losses to the wine grapes berries. Knowing the D. suzukii population dynamics in vineyards and surrounding areas, as well as the wine cultivars susceptibility, can help winegrowers to carry out the management. The objective of this study was evaluate the D. suzukii population dynamics in the field, on the forest border present around the vineyard and in its interior and evaluate the susceptibility of the main wine cultivars for São Joaquim municipality to the attack of D. suzukii in laboratory. In the vineyard, D. suzukii was monitored from November 2018 to May 2021 with weekly inspections. Plastic pot traps with a red stripe baited with the Droskidrink attractant were used, distributed among the vines and around the vineyard. Monitoring data were correlated with regional climate variables. In laboratory, through non-choice and free-choice test, the susceptibility to D. suzukii damage was evaluated in Chardonnay, Sauvignon Blanc, Sangiovese, Cabernet Franc, Cabernet Sauvignon and Merlot berries. Intact and artificially injured berries were offered to adults in plastic screened cages for 24h. Afterwards, the number of punctures, eggs, emerged adults and the period of egg-adult development were evaluated. The data were analyzed in the R environment. Through monitoring, it was found that the presence of D. suzukii adults was higher in the forest border (762) in the surroundings compared to inside of the vineyard (128). The precipitation reduced the population of D. suzukii inside the vineyard, while the average and maximum temperatures promoted an increase in the population. In free choice tests, the cultivar Sangiovese was susceptible to the attack and development of D. suzukii. The cultivar Cabernet Sauvignon showed reduced egg-adult development time compared to the other tested cultivars in no-choice test.

Abstract The species P. edulis Sims f. edulis, native to Brazil, known as purple passion fruit, has purple fruits and lower acidity. With the growing demand for passion fruits, there is greater need for research on their cultivation to reduce production costs and improve fruit quality. The adequate determination of the size and number of plots has been a fundamental limitation in studies with several crops, as it is difficult to obtain constant data on plants per plot in most experiments, making it impossible to use usual methodologies for data analysis. As a result, testing can be performed with less labor and implementation costs, making plot size optimization a step of interest. Thus, this work aims to determine the ideal size of experimental plots with purple passion fruit in the field using three methods. The variables analyzed were fruit length, fruit diameter, peel thickness, juice yield, soluble solids content, citric acid, number of fruits, and average fruit weight. The use of optimal plot size of six basic units for fruit-related variables, five for pulp-related variables, and seven basic units for production variables, is recommended.
原产于巴西的紫百香果(P. edulis Sims f. edulis)，果实呈紫色，酸度较低。随着人们对百香果的需求不断增长，为了降低生产成本和提高果实品质，对百香果栽培技术的研究日益迫切。充分确定地块的大小和数量是对几种作物进行研究的一个基本限制，因为在大多数实验中很难获得每块地块植物的恒定数据，因此不可能使用通常的方法进行数据分析。因此，可以用更少的劳动力和实现成本来执行测试，使地块大小优化成为一个有趣的步骤。因此，本工作旨在通过三种方法确定紫色百香果在田间的理想试验田面积。分析的变量包括果长、果径、果皮厚度、果汁产量、可溶性固形物含量、柠檬酸、果数和平均果重。建议果实相关变量采用6个基本单位，果肉相关变量采用5个基本单位，生产变量采用7个基本单位。
