Autores: Oliveira,Thiago F.; Pinto,Francisco A. C.; Silva,Derly J. H.
ABSTRACT The tomato crop is one of the most demanding of nitrogen fertilizers. This element on soil has an elevated mobility that can represent danger to the environment and reduces its efficiency. Therefore, the purpose of this study was to evaluate the methodology for recommending nitrogen fertilizer for tutored tomatoes with a variable rate based on nitrogen sufficiency index. The treatments consisted of a reference plot and five treatments with the nitrogen sufficiency index calculated on spectral indexes NDVI, GNDVI, MCARI, PSSRa and the SPAD value. The productivity was evaluated considering the fruits size and viability. The descriptors of quality, color, soluble solids, total acidity, titratable acidity and flavor were also evaluated. All the...

Heterosis and combining ability of dual-purpose tomato hybrids developed to meet family farmers' needs in Brazil and Mozambique
Provedor de dados: 75
Autores: Graça,António JP; Amaral Júnior,Antonio T; Rodrigues,Rosana; Gonçalves,Leandro SA; Sudré,Cláudia P; Vivas,Marcelo; Melo,Paulo CT.
Brazil is the world eighth largest tomato producer and, within the country, the tomato production chain is segmented according to fruit destination: fresh consumption and processing (industrial supply). In contrast, Mozambique does not have a differentiated chain and cultivars are expected to serve both purposes. As there are no tomato breeding programs in Mozambique, cultivars used in the country come from other regions of the world, including Brazil. This paper describes the development and assessment of tomato hybrids with dual-purpose: fresh use and processing. Five tomato genotypes (B13LD, Castone, Massag-72, "Viradoro", and "Rio Grande") were crossed in complete diallel design without reciprocal, and the general and specific combining ability (GCA...

Autores: Gomes,Gisely Paula; Constantino,Leonel Vinicius; Corte,Ligia Erpen-Dalla; Riger,Cristiano Jorge; Chaves,Douglas S de A; Gonçalves,Leandro SA.
ABSTRACT Capsicum baccatum is one of the main chili pepper species grown and consumed in South America. In Brazil, C. baccatum var. pendulum is widely cultivated, especially “dedo-de-moça” type. For most horticultural crops, including Capsicum species their diversity remains under-explored for traits related to fruit quality, since over the past half century breeding efforts have focused mainly on good agronomic performances. The investment in screening traits such as flavor, nutritional compounds and antioxidant content in traditional varieties is very important to support fruit quality breeding efforts. Thus, the objective of this study was accessing the variations into content of soluble solid, acidity, capsaicinoid, vitamin C, total phenolic compounds...

Postharvest disorders and rots can produce important economic losses in fruits stored for long time for exportation. The genetic and physiological basis of some disorders in melon (Cucumis melo L.) are unknown and particularly the possible relation with climacteric behavior. A collection of melon near-isogenic lines (NILs) (SC3-5 and seven more showing climacteric and two non-climacteric ripening pattern) were analyzed to study genetic and physiological aspects of fruit disorders and rots. Two non-climacteric (Nicolás; Inodorus Group; and Shongwan Charmi PI161375, Conomon Group) and two climacteric cultivars (Fado, Reticulatus Group; Védrantais, Cantaloupensis Group) were used as reference. The field was divided in eight blocks containing one three-plant...

Bertholletia excelsa Bonpl., também conhecida como castanheira-do-brasil, castanheira-do-pará e castanheira-da-amazônia, é uma árvore que ocorre naturalmente em grande parte da Amazônia. Entretanto, a presença de aflatoxinas B1, B2, G1 e G2 de Aspergillus spp. em amostras de castanha-do-brasil com casca e sem casca, em níveis superiores àqueles considerados seguros por países importadores, tem limitado as exportações desse produto, além de restringir o mercado interno. A presença dessas aflatoxinas nas castanhas depende da infecção e colonização dos tecidos da semente por fungos Aspergillus spp. Níveis de fatores ambientais próximos aos favoráveis à produção de aflatoxinas são encontrados na Floresta Amazônica, durante a época de queda dos frutos e...

Autores: SOUZA, J. M. L. de; CARTAXO, C. B. da C.; LEITE, F. M. N.; REIS, F. S.
Nativa da Região Amazônica, a castanheira (Bertholletia excelsa H.B.K.) é considerada uma das maiores riquezas nos estados que formam a Amazônia Brasileira. Um dos grandes problemas na conservação da castanha-do-brasil deve-se ao crescimento de fungos produtores de aflatoxinas e bactérias patogênicas, por causa das condições de umidade relativa e temperatura elevadas a que é submetida desde o momento da queda do ouriço. Assim, buscou-se identificar, em indústrias de processamento de castanha-do-brasil no Acre, os microrganismos responsáveis pela qualidade sanitária, especialmente os do grupo coliformes, bactérias mesáfilas, bolores e leveduras. Foram coletadas amostras nos meses de agosto de 2001 a maio de 2002, em cinco etapas do processamento. As...

Provedor de dados: 46
Autores: Cabodevila,V.G; Picardi,L.A; Pratta,G.R.
Segregating progeny from the tomato Second Cycle Hybrids (SCH) that were obtained from crossing RIL (Recombinant Inbred Lines) allows the detection of new genetic combinations that could increase genetic variability in F2 populations. The objectives of the present study were to evaluate eleven tomato quality traits in a segregating F2 population obtained from a SCH and, then, to characterize the molecular diversity by six AFLP (Amplified Fragment Length Polymorphism) primer combinations. Different multivariate analyses were used to assess the degree of concordance among these two approaches to detect genetic variability. Sixty-nine F2 plants were obtained by selfing the SCH (ToUNR18xToUNR1). The parental RIL were derived from an interspecific cross between...

Autores: OHASHI,THAÍS LURI; FOUKARAKI,SOFIA; CORRÊA,DANIEL SOUZA; FERREIRA,MARCOS DAVID; TERRY,LEON.
ABSTRACT  The market demand for tropical fruits has been growing steadily over the past two decades and global papaya production has grown significantly over the last few years. This sector, however, suffers greatly from postharvest losses due to reduced quantity and quality of fruits between harvest and consumption. The use of ethylene inhibitors after harvest could improve the final quality of the fruit to satisfy the consumer and also minimize waste. The physiological and biochemical responses of ‘Solo’ papayas treated with the ethylene inhibitor 1-methylcyclopropene (1-MCP) to extend storage shelf life and maintain quality during long-term storage are deeply discussed in this study. Papaya fruits arrived at Cranfield University (CU) and received a 24 h...

Gelled aspect in papaya fruit is typically confused with premature ripening. This research reports the characterization of this physiological disorder in the pulp of papaya fruit by measuring electrolyte leakage, Pi content, lipid peroxidation, pulp firmness, mineral contents (Ca, Mg and K - in pulp and seed tissues), and histological analysis of pulp tissue. The results showed that the gelled aspect of the papaya fruit pulp is not associated with tissue premature ripening. Data indicate a reduction of the vacuole water intake as the principal cause of the loss of cellular turgor; while the waterlogged aspect of the tissue may be due to water accumulation in the apoplast.

The crop load level of an apple (Malus × domestica Borkh.) tree impacts fruit yield and quality parameters, tree vigor and biennial bearing. The optimal crop load is that which allows for consistent annual cropping and fruit quality acceptable to the market. We evaluated the effect of crop load on yield and fruit quality of two low-chill apples cv. ‘Caricia’ and ‘Eva’, growing in a mild winter area. During 2010 and 2011 crop load was manually adjusted from 2 or 3 to 17 fruits cm−2 of trunk cross-sectional area (TCSA). Fruit yield was positively related to crop load in both cultivars but mean fruit weight diminished as the crop load increased. For both cultivars, the production of non-commercial and small-sized fruit increased, whereas production of...

Provedor de dados: 53
Autores: Girardi,Eduardo Augusto; Cerqueira,Thales Sandoval; Cantuarias-Avilés,Tatiana Eugenia; Silva,Simone Rodrigues da; Stuchi,Eduardo Sanches.
ABSTRACT In Brazilian regions affected by the citrus sudden death disease, sweet orange cultivation depends on the use of resistant rootstocks. Rangpur lime was mainly replaced by Swingle citrumelo and Sunki mandarin rootstocks, more drought-sensitive ones. The diversification of scion selections is also desirable aiming at the increasing demand for not from concentrate orange juice (NFC) that requires high-quality fruits. In this work, we evaluated the performance of 6 selections of Valencia (IAC, Dom João, Late Burjasot IVIA 35-2, Rhode Red SRA 360, Temprana IVIA 25 and Campbell) and Natal IAC sweet oranges grafted onto Swingle citrumelo and Sunki mandarin. The planting occurred in 2001 under rain-fed cultivation in Bebedouro, northern São Paulo state,...

Autores: Hasan,Fatimahtul Hazwani; Tajidin,Nor Elliza; Ahmad,Siti Hajar; Mohamed,Mahmud Tengku Muda; Shukor,Nur Indah Abdul.
ABSTRACT ‘Frangi’ papaya is a F1 hybrid cultivar produced by Malaysian Agrifood Corporation Bhd in 2006. Since then, ‘Frangi’ papaya is a new hybrid and its physiology may differ from another cultivars. Several importer countries, such as Japan and China, have made the vapour heat treatment (VHT) an export requirement for disinfestation of fruit flies in Malaysia. The exporting country is also required to carry out ripening treatments with ethylene before export. Therefore, the objective of this work was to determine the effects of maturity stages (4, 5 and 6) and ethylene treatments on ripening characteristics of vapour heat treated papaya during storage at 25 °C. Papaya fruits were treated with VHT systems. After VHT, the fruits were exposed with 100...

ABSTRACT The Gala cultivars represent about 65% of the Brazilian apple production, however, it has a short harvest period, making necessary to use technologies that anticipate or delay fruit maturation. A widely used technology is the preharvest application of growth regulators. The objective of this investigation was to evaluate the effect of preharvest application of naphthalene acetic acid (NAA) combined with aminoethoxyvinylglycine (AVG) and 2-chloroethylphosphonic acid (Ethephon), on the quality of ‘Brookfield’ apple at harvest and after eight months controlledatmosphere (CA)(1.2 kPa O2 and 2.0 kPa CO2) storage followed by seven days of shelf life at 20 °C. The treatments were: [1] Control: application of water only; [2] NAA (40 g.ha-1); [3] NAA (40...

Autores: Prado,Renato de Mello; Natale,William; Corrêa,Márcio Cleber de Medeiros; Silva,José Antônio Alberto da.
To determine the effects of lime application on the postharvest quality of carambola fruit, an experiment with carambola trees cultivated on an acid soil was conducted at the Bebedouro, São Paulo, Brazil. The trees were treated with increasing doses of lime during the pre-planting period. Liming led to a increase in calcium concentration of carambola leaves and fruits. Adequate nutrition of the plant with calcium improved post-harvest fruit quality, permitting a longer (~ 2 days) period of storage under ambient conditions.

Effect of Arbucula Myrrhizal Fungi on an Ecological Crop of Chili Peppers (Capsicum annuum L.)
Provedor de dados: 117
Autores: Castillo R,Claudia ; Sotomayor S,Leonardo ; Ortiz O,César; Leonelli C,Gina; Borie B,Fernando; Rubio H,Rosa.
Mapuche farmers in southern Chile have been cultivating local ecotypes of chili pepper (Capsicum annuum L.), called locally “Cacho de cabra” for many decades. It is used to make “merkén”, a condiment that is consumed locally and exported. This vegetable requires a nursery stage and can obtain nutritional benefits from symbiotic associations such as mycorrhizal fungi, achieving a better adaptation to transplanting. Arbuscular mycorrhizal fungi (AMF) are obligate biotrophes appearing in abundance in agroecosystems with conservation management. The aim of this study was to compare effectiveness of two AMF, a commercial mycorrhizal inoculant (IC, Glomus intraradices) and another native (IN, Glomus claroideum) with a control without inoculation (-I) on the...

Provedor de dados: 117
Autores: Undurraga M,Pedro L; Olaeta C,José A; Cancino,Cristian.
There is some controversy regarding the respiratory pattern of loquat (Eriobotrya japonica [Thunb.] Lindl.). Thus in order to provide information on this aspect of loquat, fruit of 50-70 g, from cv. Golden Nugget were harvested in four stages of maturity: green (BBCH 709), color break (BBCH 801), yellow (BBCH 807), and orange (BBCH 809). The parameters evaluated in each stage were: soluble solids, titratable acidity, respiration, ethylene generation, and activity of the enzymes pectin methyl esterase (PME), peroxidase, polyphenoloxidase (PPO), polygalacturonase (PG), and cellulose, and the soluble solids:acidity ratio was calculated. The results show that ethylene concentration increased at the time of color break, which was not the case for the change in...

Provedor de dados: 117
Autores: Homer,Ian; García-Ramos,Francisco Javier; Ortiz-Cañavate,Jaime; Ruiz-Altisent,Margarita.
A non-destructive impact sensor to measure on-line fruit firmness was evaluated. This sensor is an adaptation of a static model used in the laboratory to measure fruit quality and was installed in an experimental fruit packing line with a commercial sizer chain. The firmness index is related to the acceleration-time curve supplied by an accelerometer attached to an impacting arm. The main objective of this study was to evaluate sensor performance and sources of variation. We made classification trials on three fruits: peaches (Prunus persica (L.) Batsch), apples (Malus domestica Borkh.), and pears (Pyrus communis L.), as well as working trials, such as placing the fruit, orientation, and others. The sensor works correctly at a speed of 7 fruits s-1 (0.63 m...

Effects of fruiting spur thinning on fruit quality and vegetative growth of sweet cherry (Prunus avium)
Provedor de dados: 118
Autores: Ayala,Marlene; Andrade,María P.
High density sweet cherry (Prunus avium) orchards using highly productive cultivars and dwarfing rootstocks usually require crop load regulation to achieve high quality fruit. Among the strategies used to reduce crop load in highly productive combinations, fruiting spur thinning (FST, spur extinction) before budbreak has been suggested to be an effective way to improve fruit size. Currently, there is little information about the effect of spur thinning on sweet cherry orchards using self-fertile cultivars grafted on vigorous rootstocks. For this reason, the objective of the present study was to evaluate the effects of manual FST on fruit quality and vegetative growth of the cultivar 'Lapins' grafted on the rootstock 'Mazzard F-12/L with 0, 50 and 75% spur...

Pruning effects on vegetative growth and fruit quality of 'Bing'/'Gisela®5' and 'Bing'/'Gisela®6' sweet cherry trees (Prunus avium)
Provedor de dados: 118
Autores: Villasante,Macarena; Godoy,Soledad; Zoffoli,Juan Pablo; Ayala,Marlene.
Annual pruning is one of the most efficient ways to regulate crop load and renew fruiting wood in highly productive sweet cherry (Prunus avium L.) combinations. Although Chilean growers did not previously prune cherry trees of more vigorous combinations, in recent years, the adoption of more dwarfing rootstocks and self-fertile cultivars has led to the inclusion of annual pruning as a practice in modern orchards. At first, this alteration in orchard management practices was not considered by growers, and thus, many of the initially established cherry orchards were not pruned as intensively as they should have been. As a consequence, many trees showed a reduction in fruit quality after 4 or 5 years of being planted, as they became overcropped and,...

Autores: Campos-Vargas,Reinaldo; Zamora,Pablo; Contreras,Rodrigo; Köhler,Hans; Zúñiga,Gustavo E; Pérez-Donoso,Alonso; Defilippi,Bruno G.
Table grape (Vitis vinifera L.) quality includes the condition of both the berries and the rachis. In the present report, physiological parameters of Red Globe rachises from fully elongated inflorescences (RFEI) and from mature clusters were studied after storage at 0 or 20 °C for different durations. To understand changes in rachis physiology as a result of changes in temperature conditions and storage time, the activities of superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) were measured. In addition, hydrogen peroxide content, membrane lipoperoxidation (TBARS), total phenolic compounds and antioxidant capacity (FRAP) were assayed. TBARS was higher in mature rachises than in RFEI. This parameter remained constant throughout...

ABSTRACT: The aim of this research was to evaluate the interaction between maturity stages and temperature on fruit quality of ‘Guarani’ blackberries stored under controlled atmosphere (CA). The experiment was conducted in a factorial scheme (2x2), evaluating two ripening stages (E1: red-color and E2: black-color of fruits) and two temperatures (1°C and 5°C). The fruit were stored in CA (10.0kPa O2+15.0kPa CO2) and 98±1% of relative humidity (RH). Results showed that the principal component 1 (PC I) and principal component 2 (PC II) corresponded to 92.84% of the overall variation of the evaluated variables. Harvest should not be performed in the early maturity stage, because ‘Guarani’ blackberries do not develop all quality of consumer. ‘Guarani’...
