Potassium trifluoroborates have gained significant utility as coupling partners in organic synthesis, particularly in the Suzuki-Miyaura coupling reaction. Recently, they have also been used as radical precursors under oxidative conditions to generate carbon-centered radicals. These versatile reagents have found new applications in photoredox catalysis, including radical substitution, conjugate addition reactions, and transition metal dual catalysis. In addition, this photomediated redox neutral process has enabled radical-radical coupling with persistent radicals in the absence of a metal, and this process remains to be fully explored. In this study, we report the radical-radical coupling of benzylic potassium trifluoroborate salts with isolated acyl azolium triflates, which are persistent radical precursors. The reaction is catalyzed by an organic photocatalyst and forms isolable tertiary alcohol species. These compounds can be transformed into a range of substituted ketone products by simple treatment with a mild base.

: The objective was to determine the effects of doses of controlled-release fertilizer and container volume on the initial growth and quality of Hymenaea cour-baril seedlings. The experimental design was completely randomized in a 2 x 4 factorial scheme, corresponding to two container volumes (1.8 and 2.2 L) and four doses of controlled-release fertilizer (0, 1.5, 3.0 and 4.5 g L -1 substrate) with eight replicates, each consisting of five seedlings (one in each container). The variables evaluated were: shoot height (H), stem diameter (SD), shoot dry mass (SDM, g plant -1 ), root dry mass (RDM, g plant -1 ), total dry mass (TDM, g plant -1 ), Dickson quality index (DQI), root volume (RV), nitrogen balance index (NBI) and chlorophylls. Controlled-release fertilizer at doses of 1.5 and 3.0 g L -1 provide Hymenaea courbaril seedlings with quality and sturdiness in both container sizes. Controlled-release fertilizer at the dose of 4.5 g L -1 is not indicated to obtain high quality standard in seedlings of Hymenaea courbaril , regardless of container volume.

Abstract The characterization of clones is a very important step in genetic certification programs, as it describes and recognizes the plant material at every stage of production, allowing the monitoring of genetic quality, improvement and conservation of the germplasm. The aim of this work was to morphologically characterize two elite banana clones. The experimental design applied was in randomized blocks, with four replications, with six plants per parcel. The treatments consisted of two elite banana clones, Prata Gorutuba R1 and Prata Gorutuba R2 and four commercial cultivars: Prata Gorutuba, Prata Ana, Grande Naine and BRS Princesa. The morphological characterization was carried out in the second production cycle (daughter plant), using 23 qualitative descriptors, visually evaluated, classified according to the instructions for carrying out the distinguishability, homogeneity and stability (DHS) tests of banana cultivars. The elite clones Prata Gorutuba R1 and R2 differed from the cultivars Grande Naine and BRS Princesa regarding the descriptors tapering of the pseudostem, predominant color of the pseudostem, intensity of anthocyanin coloration and color of the underside of the basal sheath. The descriptors made it possible to group elite clones into the Prata group, a group that predominates in crops in Brazil, with characteristics already widely accepted by the market.

Abstract Residues are generated after the processing of citrus fruits and can be used for essential oil extraction. Thus, the objective of this work was to evaluate the composition, yield, and quality of the proven oil of 30 orange varieties, as an alternative for the better use of its residues. The peels were crushed and subjected to hydrodistillation in a Clevenger-type. The samples were submitted to an Entirely Randomized Design (DIC) and the results were analyzed in Analysis of Variance, Principal Component Analysis, and Hierarchical Cluster Analysis. The greatest gains in essential oil were yielded by the varieties Valencia IAC (5.57%), Pera DP 06 (4.75%), Hamlin 20 (4.58%), and Pera DP 25 (4.28%). Valencia IAC has the potential to extract up to 7.24 kg of essential oil per ton of orange. Limonene represents 93.18 to 99.61% of the oil components, being the major compound among all varieties. Some varieties did not describe secondary compounds or more than one. These components are highly antioxidant and of great importance in the production of cosmetics, personal care products, homeopathy, help gastrointestinal diseases, among other uses. It is possible to conclude that the varieties have different compounds and oils, even when submitted to the same drying and oil extraction process, being the intrinsic characteristics of each variety.

Abstract The main limitation of the micropropagation of camu-camu (Myrciaria dubia) is related to in vitro contamination. In order to overcome contamination, the effect of essential oils was studied as an alternative to conventional chemical treatments. This study aimed to analyze the action of essential oils from four condiment and medicinal plants (Oregano, Origanum vulgare L.; Garlic, Allium sativum L.; Citronella, Cymbopogon nardus L.;and Ginger, Zingiber officinale Rosc.) in reducing microbial contamination growth and on the survival rate of explants in the micropropagation of camu-camu. The antimicrobial activity of essential oils was analyzed on the in vitro contamination of tissue culture from camu-camu at concentrations of 0.5, 1, 2, 3 and 4 µL mL-1 in woody plant medium (WPM), emulsified with 1% Polysorbate 80 (Tween 80). The antibacterial activity of essential oils on strains isolated from camu-camu tissue culture was also analyzed using agar diffusion and broth microdilution methods. The use of essential oils allowed a reduction in the rate of in vitro contamination in tissue culture, it being observed that, from the concentration of 2 µL mL-1, there was no manifestation of fungal contaminants, with a significant reduction in the rate of bacterial contamination, with the exception of ginger essential oil that showed significant contamination in all analyzed concentrations. Inversely in relation to the reduction in microbial growth in vitro, there is an increase in explant oxidation as concentrations increase, with citronella and oregano oils showing phytotoxic potential from the lowest concentrations. Garlic essential oil showed better balance, with lower oxidation rates and greater control of microorganisms in tissue culture at concentrations of 0.5 and 1 µL mL-1. Oregano and citronella essential oils showed better antibacterial activity in the agar diffusion test.

Abstract The objective of this study is to describe the agronomic attributes of the SCS443 Isadora apple tree cultivar and to highlight its potential use in Brazil. Obtained by the hybridization made at Epagri in 2001 between ‘Imperatriz’ and ‘Cripps Pink’, after 20 years of agronomic evaluations carried out in Caçador-SC and Fraiburgo-SC, ‘SCS443 Isadora’ was originated. This cultivar has a wide plasticity of adaptation to the southern Brazilian climate due to the medium chilling requirement to overcome dormancy. It has greater resistance to the main apple diseases than cv. Gala and fruit harvest is later than cv. Fuji. Its apples have a red skin and firm flesh (=18 lb), with high sugar content (= 14.5 %) and very crunchy and juicy texture, as well as high storage ability in post-harvesting. ‘SCS443 Isadora’ apples can be stored for 8 months, even in refrigerated air atmosphere chambers (21% O2) with inhibition of the ethylene response by the use of 1-methylcyclopropene (1-MCP). Even stored for long periods of time, the indices of quality loss, physiological disorders and fruit rotting in ‘SCS443 Isadora’ apples are lower than on Gala and Fuji apples.

Abstract Cupuassu (Theobroma grandiflorum)-based agroforestry system (AFS) can be used for restoration of vegetation around springs and riparian forests of water sources (rivers, streams, lakes etc.), subject to constant flooding. The objectives of this work were to study the relations between morphophysiological traits when flooding occurs, determining the most important to assess genotypes’ tolerance, and evaluate the ability of cupuassu genotypes to express alternative phenotypes and grow efficiently, in order to select materials capable of sustaining hypoxic conditions. The trial was carried out in a greenhouse, in a completely randomized design with a 16 x 2 (16 progenies and two water regimes) factorial scheme and four replications. Treatments started six months after the seedlings were transplanted. 15 traits related to vegetative development, biomass accumulation and physiology were measured for the experimental evaluation. Correlations and principal components were estimated to study the traits’ interrelationships and identify the most important to assist progeny selection. The results revealed that, among the evaluated traits, ten were sufficient to explain the variability within the population and four were elected as the most relevant to select the best progenies. 75% of the genotypes showed tolerance to partial flooding and based on performance and plasticity, we selected G174, G48 and G56 for a broader spectrum and G44, G47 and G51 for hypoxic conditions only. The promising evidence pointed out here will need to be corroborated with field tests, so that the cupuassu tree can be recommended in the recovery of environments subject to hypoxia.

Abstract The objective of this work was to characterize the phenology and the viticultural performance of advanced selections of grapevines resistant to fungal diseases obtained by the Julius Kühn Institute, Institute for Grapevine Breeding Geilweilerhof. The experiment was conducted in three different grape-growing regions of Santa Catarina State, Brazil, in the municipalities of Videira (840 m), São Joaquim (1110 m) and Curitibanos (1000 m) during the seasons of 2018/2019 and 2019/2020. The advanced selections evaluated were the reds Gf.2004-043-0010 (Gf.10), Gf.2004-043-0013 (Gf.13), Gf.2004-043-0021(Gf.21) and the white Gf.2004-043-0004 (Gf.04). We found that pyramided loci Rpv1+Rpv3.1 and Run1+Ren3 were present, which confer resistance to downy mildew and powdery mildew, respectively. The phenological stages events evaluated were budbreak, full bloom, veraison and maturity. The productive variables evaluated were fertility index, number of clusters, cluster weight and yield. Technological maturity parameters were soluble solids, total acidity and pH. To understand the relationship between the variables and whether these relationships changed depending on the cultivation environment the Multi-Trait Genotype–Ideotype Distance Index was used to rank the genotypes based on the analyzed traits. For most selections, the budbreak occurred in the second half of September; full bloom occurred from late October to mid-November; the veraison occurred between the end of December and mid-January; and maturity occurred between the end of January and February. The earliest budbreak occurred in the vineyard located at the highest altitude (1110 m - São Joaquim), while the earliest full bloom, veraison and maturity occurred in the lowest altitude vineyard (840 m – Videira). All selections produced grapes with adequate concentrations of pH and total acidity to produce quality wines. Except for Gf.13, all selections produced grapes with levels of soluble solids suitable to produce quality wines. Based on the Multi-Trait Genotype–Ideotype Distance Index (MGIDI) the selections Gf.13 and Gf.10 are the most promising genotypes for the Videira region (840 m) and Gf.10 is the most promising genotype for the regions of higher altitude, 1000 m and 1110 m.
摘要/ Abstract摘要:本研究的目的是研究由Julius k研究所和Geilweilerhof葡萄育种研究所获得的葡萄抗真菌病高级选育品种的物候特征和葡萄栽培性能。实验在巴西圣卡塔琳娜州的三个不同的葡萄种植区进行，分别是维迪拉市(840米)、s o Joaquim市(1110米)和库里提巴诺斯市(1000米)，分别于2018/2019和2019/2020年进行。评价的高级品种为红色品种Gf.2004-043-0010 (Gf.10)、Gf.2004-043-0013 (Gf.13)、Gf.2004-043-0021(Gf.21)和白色品种Gf.2004-043-0004 (Gf.04)。结果发现，水稻对霜霉病和白粉病具有抗性的基因座分别为Rpv1+Rpv3.1和Run1+Ren3。评价的物候阶段事件为花蕾期、花期、花期和成熟期。评价的生产变量为肥力指数、簇数、簇重和产量。技术成熟度参数为可溶性固形物、总酸度和ph。为了了解这些变量之间的关系以及这些关系是否随栽培环境的变化而变化，采用多性状基因型-理想型距离指数(Multi-Trait Genotype-Ideotype Distance Index)对分析性状进行基因型排序。对于大多数品种来说，发芽发生在9月的下半月;花期为10月下旬至11月中旬;发生在12月底至1月中旬之间;在1月底到2月底之间到期。最高海拔的葡萄园(1110 m - o Joaquim)最早发芽，而最低海拔的葡萄园(840 m - Videira)最早开花、变熟和成熟。所有选择生产的葡萄具有足够的pH值和总酸度浓度，以生产优质葡萄酒。除Gf.13外，所有品种的葡萄都具有适合生产优质葡萄酒的可溶性固体含量。基于多性状基因型-理想型距离指数(MGIDI)，选择Gf.13和Gf.10是vidira地区(840 m)最有希望的基因型，选择Gf.10是海拔较高地区(1000 m和1110 m)最有希望的基因型。

The experiment was conducted in three different grape-growing regions of Santa Catarina State, Brazil, in the municipalities of Videira (840 m), São Joaquim (1110 m) and Curitibanos (1000 m) during the seasons of 2018/2019 and 2019/2020. The advanced selections evaluated were the reds Gf.2004-043-0010 (Gf.10), Gf.2004-043-0013 (Gf.13), Gf.2004-043-0021(Gf.21) and the white Gf.2004-043-0004 (Gf.04). We found that pyramided loci Rpv1+Rpv3.1 and Run1+Ren3 were present, which confer resistance to downy mildew and powdery mildew, respectively. The phenological stages events evaluated were budbreak, full bloom, veraison and maturity. The productive variables evaluated were fertility index, number of clusters, cluster weight and yield. Technological maturity parameters were soluble solids, total acidity and pH. To understand the relationship between the variables and whether these relationships changed depending on the cultivation environment the Multi-Trait Genotype–Ideotype Distance Index was used to rank the genotypes based on the analyzed traits. For most selections, the budbreak occurred in the second half of September; full bloom occurred from late October to mid-November; the veraison occurred between the end of December and mid-January; and maturity occurred between the end of January and February. The earliest budbreak occurred in the vineyard located at the highest altitude (1110 m - São Joaquim), while the earliest full bloom, veraison and maturity occurred in the lowest altitude vineyard (840 m – Videira). All selections produced grapes with adequate concentrations of pH and total acidity to produce quality wines. Except for Gf.13, all selections produced grapes with levels of soluble solids suitable to produce quality wines.

ABSTRACT The objective of this study was to evaluate the physico-chemical characteristics of fruits of 58 sweet orange tops cultivars on four rootstocks, namely: ‘Sunki Tropical’ mandarin and ‘Trifoliata’ Citrandarin ‘San Diego’, ‘Riverside’ and ‘Indio’. For this purpose, a completely randomized experimental design was used, in a factorial scheme (58 x 4). The characteristics analyzed were: equatorial diameter, fruit mass, peel thickness, number of seeds, soluble solids, titratable acidity, Ratio and juice yield. All the characteristics analyzed were influenced by both the tops cultivar and the rootstock, demonstrating that both factors interfere in the physicochemical quality of the fruits. The tops ‘Pera D-3’, ‘Pera Olimpia’, ‘Pera Bianchi’, ‘Jaffa’ and ‘Westin’ on all rootstocks evaluated showed characteristics in their fruits with soluble solids greater than 10 ºBrix, Ratio above 9.5 and juice yield greater than 45%, characteristics that define fruits with quality standards. Also, the tops ‘Pera Olimpia’, ‘Sincorá’ and ‘Westin’ on the rootstock ‘Sunki Tropical’, ‘Pera D-3’, ‘Pera D-25’, ‘Sincorá’, ‘Aquiri’ and ‘Russas P.S.’ on the rootstock ‘San Diego’, ‘Pera C-32’, ‘Pera D-3’, ‘Pera D-6’, ‘Pera E-6’, ‘Pera Bianchi’, ‘Pera CE-03 ‘, ‘Salustiana’ and ‘Westin’ on ‘Riverside’ rootstock are suitable for the juice production industry with Ratio between 14 and 16 and juice yield greater than 50%. It is also worth noting that the tops ‘Crescent’, ‘Natal Folha Murcha’, ‘Valencia Midknight’ and ‘Valencia Delta’ produced fruits without seeds on all rootstocks.

ABSTRACT The characteristics of four genetic materials of feijoa (GM7, GM12, GM26, and GM27) after 7, 15, and 30 days of refrigerated storage (5°C and 97% RH) followed by 7 days of shelf-life (20°C and 80% RH) were analyzed. Respiratory activity, weight loss, flesh firmness, external and internal color, internal browning, total polyphenol content (TPC), and total antioxidant capacity (TAC) were determined. GM12 exhibited the best respiratory activity in most of the evaluated moments. Significant weight loss, i.e., 5%–7% of the initial weight at 7+7 and 15+7 days of storage and 8%–10% at 30+7 days was observed, especially in GM26. At harvest, flesh firmness was 38–57 N and reduced by 50%–65% in shelf-life. The external color did not show noticeable differences. Internal browning, which increased with the storage progress, was less noticeable in GM7, possibly owing to its lower TPC and TAC. GM26 and GM27 were the least firm and had the maximum weight loss. Although GM7 had a lower content of functional compounds, it had less internal browning. GM12 presented significant respiratory activity, high content of functional compounds, and acceptable firmness retention and weight loss, making it the most promising genetic material analyzed in this study.
