Abstract:
SUMMARYThe centre of origin of cashew is believed to be Brazil, from where it has spread since the 16th century throughout the tropics. In recent years, Vietnam has surpassed India to become the world's largest producer of cashew nut. Most of the research on the water relations of cashew has been done in Brazil, where it is both a large-scale commercial and a smallholder crop, and in Australia, where cashew is a possible emerging new crop. There are two ‘types’ of cashew: ‘talls’ and ‘dwarfs’. Both are evergreen trees in which vegetative growth occurs in a series of flushes. Flowers form annually on the end of branches in the dry season, and flowering continues for two to four months. It then takes about two months from pollination for the nut to mature. Roots can extend to great depths (>5 m), while cashew's wide-spreading rooting habit is critical to its successful adaptation to semi-arid/dry conditions. The optimum temperature for CO2 assimilation is in the range 25–35 °C. Progressive closure of the stomata occurs at saturation deficits of the air >1.5 kPa. In the field, differences in rates of gas exchange between irrigated and unirrigated cashew trees only become apparent three or four months after the end of the rains, the stomata playing an important role in maintaining a favourable leaf water status in dry conditions. Sap flow measurements indicate transpiration rates of 20–28 L d−1 tree−1. Irrigation can be beneficial during the period from flowering to the start of harvest, but reliable estimates of water productivity have yet to be established. The best/only estimate is 0.26 kg (nut in shell) m−3 (irrigation water). There is a continuing need to develop a method to estimate the water requirements of cashew, to identify where and when irrigation of cashew is likely to be justified and to develop a practical irrigation schedule.

Abstract:
Abstract Multivariate analyses were carried out on fifty-nine germplasm accessions of cashew derived from both local and exotic populations established at the research plots of Cocoa Research Institute of Nigeria (CRIN), Ibadan, southwestern Nigeria, to assess the extent of variability and pattern of genetic diversity among these cashew populations. Data collected on 36 quantitative and 33 qualitative plant characters were subjected to taximetric tools of Euclidean distance of complete linkage (furthest neighbour) and principal component analysis (PCA). The multivariate analyses tentatively grouped the selections into four distinct morphogenetically diverse clusters. The groupings appear to be a function of origin, eco-geographical distribution, genetic and/or agronomic affinity of the selections. Brazilian populations distinctly clustered together in two major groups while local clones and Indian selections dominated the other two major clusters with each group having its unique fruiting and tree growth habits. The clustering pattern at sub-cluster levels clearly reflects affinity of each genetic population. The principal component analysis and the potency indices showed that fruit characters are the most discriminating parameters for delineating cashew at the varietal level.

Abstract:
SUMMARYThe pollination requirements of cashew (Anacardium occidentale L.), an andromonoecious tree, were studied in NE Brazil, where cashew is indigenous. It was shown through the use of bagging and caging experiments, controlled hand-pollination and emasculation of flowers, that the wind plays little role in cashew pollination and that cashew is self-fertile, although only pollen from the large stamen, either male or hermaphrodite-derived, can effect pollination. Insects appear to be the major pollinators of cashew, in agreement with the pollination syndrome suggested by the morphology of its flowers. Direct observations of insects visiting flowers and counts of pollen grains adhering to such insects suggest that the honey bee (Apis mellifera L.), although a non-native insect, is the major pollinator of commercially grown cashew in NE Brazil.

Abstract:
The culture of cashew (Anacardium occidentale L.) is increasing in the Far North Cameroon. But, the productivity is threatened by the development of diseases in orchads. Therefore, the aim of this study is to identify diseases and pathogens involved in cashew cultivation. The diseases were identified under the basis of the identification keys. The fungal structures were characterized using an optical microscope and the pathogenicity test were carried out. Incidence, severity and prevalence of diseases were assessed in the dry season and the rainy season. Seven diseases and seven pathogens have been identified: anthracnose (Colletotrichum gloeosporioides Penz), pestalotia leaf spot (Pestalotia heterocornis), alternaria (Alternaria solani), drying of buds (Colletotrichum gloeosporioides, Phomopsus anacardii and Curvularia lunata), dieback (Colletotrichum sp. and Lasiodiplodia sp.), blight of leaves (Pestalotia heterocornis and Colletotrichum gloeosporioides) and powdery mildew (Oidium anacardii Noack). Whatever the season; anthracnose, pestalotia leaf spot an drying of buds are diseases with higher incidence (more than 85, 60 and 75% respectively) and higher prevalence. The severity of the diseases varied according to the location and season. Pathogenicity test revealed that all the test fungi were pathogenic to their respective host parts except cashew powder mildew and alternaria. The results of this study represent database for implementation of integrated disease management approaches in Cameroon.

Abstract:
Description of subject: One of the main constraints to cashew crop development in Benin and Africa is the unavailability of efficient planting material for the plantations establishment. This constraint is largely responsible for the low level of nut yieldsobtained in cashew plantations. Objective: This study aimed to assess the agronomic performances of 29 different cashew mother trees established in the germplasm of the Central Agricultural Research Center (CRA-Centre) of the National Agricultural Research Institute of Benin located in Save, Central region, in sightof selecting high-performance clones to be distributed in rural areas. Materials and Methods: Nuts production, unit nuts weight and the kernelrate data were collected on 29 cashew mother trees during the harvest seasons from 2017 to 2020. These data were submitted to the analysis of variance and comparison of the means tests with software R. Results: The average nut yields of the 29 cashew mother trees varied from 0.85 to 11.98 kg / tree with a general average of 3.57 kg / tree at the age of 7 years old. Average unit nut weights ranged from 4.61 to 8.28 g with an overall average of 6.40 g. The average kernel ratio of nuts ranged from 24.08% to 32.46% with an overall average of 27.18%. The average weight of akernel varied from 1.43 to 2.15g with an average of 1.71g. At the end of the fouryears assessment, five of the 29 cashew mother trees with a minimum nut yield of 5 kg / tree were preselected as the first efficient cashew clones from Benin. Conclusion: These preliminary results are very important for the cashew breeding program in Benin. Furtherstudieswill plan to assess the cashew mother trees performance at 10, 15, 20 and 25 years old.

Abstract:
Baubau City is one of the cashew (Anarcadium occidentale L.) producer area in Southeast Sulawesi with area of 820 ha. This large area of cashew cultivation was not compensated with the productivity caused of low production. An effort to overcome this problem is identifying the growth and yield characters of cashew to apply the good agricultural practices for cashew plantation. The objective of this research was to determine the growth and yield of two cashew varieties at different tree ages; and to identify the relationship between the characters and the productivity of cashew trees in Baubau City. This research was arranged by oversite design with 2 varieties (the cashew with red pseudo-fruit and the cashew with yellow pseudo-fruit), 4 ages of cashew plant (5 years old, 17 years old, 26 years old, 37 years old) and 5 replications. The results showed that both varieties had no significantly different on growth and yield characters. At 37 years old, cashew trees still demonstrated the increasing of the productivity due to the increasing of growth and yield component i.e. plant biomass, the number of flower, the number of cashew nut per plant and cashew nut weight per kernel.

The Anacardium occidentale L, popularly known as cashew tree, occupies an important place among the fruit trees due to the increasing commercialization of its main products. In northeastern Brazil, its cultivation is one of the main agricultural activities in the region. Concentrating in the states of CearÃ, Piauà and Rio Grande do Norte, it is used in folk medicine for various therapeutic purposes, including as an antimicrobial. The cashew apple bagasse is obtained after extracting the juice, being a major source of waste of agribusiness. The aim of this study was to evaluate the antimicrobial and antibiofilm potential of the hydroalcoholic extract of the cashew apple pomace (ECAP) against the Streptococcus mutans. It was determined the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and the preventive assay for biofilm formation through biomass quantification. The Streptococcus mutans strain UA159 was used for this intention. The antimicrobial assay results showed that the ECAP was considered bactericidal (250μg.mL) and was considered bactericidal at the concentration of 1000μg.mL. Inhibition in the biomass was observed at the minimum concentration of 250μg.mL. Thus, it was concluded that the EPAC shows antimicrobial and antibiofilm activity against Streptococcus mutans. These results demonstrate the potential of the ECAP as a possible biotechnological product in the field of dentistry.

Anacardium occidentale, family Anacardiaceae, is popularly known as cashew tree and it is widely used as food and medicine. This study aimed to review data on antimicrobial properties of Anacardium occidentale, to evaluate the antioxidant and antimicrobial action and to investigate the chemical composition of the extracts of flowers (EBFL), leaves (EBFO) and stem bark (EBC) of A. occidentale, to evaluate the antimicrobial activity of the byproduct obtained in order to use it in the prophylaxis and adjunctive treatment of caries. This review considered publications by Medline, Lilacs, Scielo, Chemical Abstracts, PubMed, Biological Abstract, Web of Sciences and Highwire, between 1980 and 2011, using the descriptors: Anacardium occidentale, antimicrobial, antibacterial, antifungal and pharmacological activity and cashew. The antioxidant activity was determined by DPPH assay and the antimicrobial activity by agar diffusion, broth dilution, determination of the minimum bactericidal concentration (MBC) or minimum fungicide concentration (MFC), using standard strains of Streptococcus mutans, Lactobacillus acidophilus, Staphylococcus aureus, MRSA, Enterococcus faecalis, Streptococcus pyogenes, Pseudomonas aeruginosa, Proteus mirabilis, Escherichia coli, Klebsiella pneumoniae, Helicobacter pylori and Candida albicans and clinical samples of Salmonella choleraesuis, Candida albicans and Candida tropicalis. The chemical composition was determined by colorimetry, chromatography and spectroscopy. The EBFL, more active, was fractionated and the fractions were also evaluated for antibacterial action. Regarding the literature review, 44 articles and 3 dissertations about antimicrobial properties of cashew tree were found. Bark extracts were the mostly used in those researches (30%). Staphylococcus aureus, including MRSA strains were the most studied microorganisms (68%). All extracts have showed antioxidant activity compared to quercetin. On the other hand, the result of experimental protocols showed that the EBFL was presented as the one with the most active antimicrobial action against all microorganisms evaluated either in planktonic cultures or the biofilm. The fraction F1 and bioproduct-based EBFL have also showed potent antimicrobial activity. In EBFL there were identified organic acids, alkaloids, phenolics, hydrolysable tannins, flavones, flavonols, xanthines, steroids and triterpenes. This is the first research on the antioxidant and antimicrobial properties of the flowers of A. occidentale on the prophylactic and therapeutic use in oral diseases, particularly caries and candidiasis, activities that may be related to the presence of flavonoids, tannins, organic acids, alkaloids and phenolic compounds such as anacardic acid, cardol and cardanol.
Anacardium occidentale L. (Anacardiaceae), espécie nativa do Brasil, é conhecida popularmente como cajueiro e muito utilizada como alimento e medicamento. O presente estudo teve como objetivos: organizar os dados publicados sobre as propriedades antimicrobianas de Anacardium occidentale, avaliar a ação antioxidante e antimicrobiana e investigar a composição química dos extratos das flores (EBFL), folhas (EBFO) e da casca do caule (EBC) de A. occidentale e avaliar a atividade antimicrobiana de um bioproduto obtido, visando sua utilização na profilaxia e tratamento auxiliar da cárie. A revisão considerou publicações de: Medline, Lilacs, Scielo, Chemical abstracts, PubMed, Biological Abstract, Web of Sciences e Highwire, entre 1980 e 2011, usando como descritores: Anacardium occidentale e as atividades antimicrobiana, antibacteriana, antifúngica e farmacológica e caju. A ação antioxidante foi determinada pelo ensaio de 2,2-difenil-picrilhidrazila (DPPH) e a antimicrobiana por difusão em agar, diluição em caldo e determinação da concentração bactericida (CBM) ou fungicida (CFM) mínima, utilizando cepas padrão de Streptococcus mutans, Lactobacillus acidophilus, Staphylococcus aureus e MRSA, Enterococcus faecalis, Streptococcus pyogenes, Pseudomonas aeruginosa, Proteus mirabilis, Escherichia coli, Klebsiella pneumoniae, Helicobacter pylori, Candida albicans e amostras clínicas de Salmonella choleraesuis, Candida albicans e Candida tropicalis. A composição química foi determinada por colorimetria, cromatrografia e espectroscopia. Do extrato das flores (EBFL), o mais ativo, foram obtidas frações que foram avaliadas quanto à ação antimicrobiana. Em relação a revisão de literatura foram encontrados 44 artigos e 3 dissertações sobre propriedades antimicrobianas do cajueiro. A maioria dos estudos utilizou extratos da casca (30%) e Staphylococcus aureus, incluindo as cepas MRSA, foram os micro-organismos mais estudados (68%). Nos ensaios para determinar a atividade antioxidante todos os extratos apresentaram valores semelhantes a quercetina, utilizada como controle positivo. Os resultados dos protocolos experimentais mostraram que o EBFL apresentou ação antimicrobiana mais efetiva por inibir o crescimento de todos os micro-organismos testados, tanto em culturas planctônicas como no biofilme. A fração F1 e um bioproduto à base de EBFL também apresentaram potente ação antimicrobiana sendo tão efetivos sobre micro-organismos cariogênicos quanto à clorexidina. No EBFL foram identificados ácidos orgânicos, alcaloides, compostos fenólicos, taninos hidrolisáveis, flavonas, flavonóis, xantinas, esteroides e triterpenos. Concluímos que as propriedades antimicrobianas e antioxidantes das flores podem estar relacionadas à presença de flavonoides e/ou de compostos fenólicos tais como ácidos anacárdicos, cardol e cardanol. Importante ressaltar que este trabalho é o primeiro relato sobre de A. occidentale quanto ao uso profilático e terapêutico em doenças bucais, em especial, a cárie e a candidíase.

Resumo: A goma do cajueiro (GC) é um produto isolado do exsudado bruto do cajueiro e tem sido mencionada como uma possível alternativa a substituir a goma arábica na indústria de alimentos. A alta pressão dinâmica (APD) é apresentada como uma opção a modificação física dos polissacarídeos a fim de melhorar suas propriedades tecnológicas. Dessa forma, o trabalho teve como objetivo avaliar o efeito da APD nas características tecnológicas da GC. O exsudado bruto foi purificado e a goma caracterizada quanto à composição centesimal, potencial zeta e reologia. Em seguida GC nativa (sem processamento-controle) e processada a APD foram investigadas quanto suas características tecnológicas (solubilidade e capacidade de absorção de água (CAA) nas temperaturas 30, 60 e 90ºC, capacidade de absorção de óleo (CAO), reologia e propriedades emulsificantes) comparando-as com os resultados obtidos para goma arábica (GA). A GC apresentou 10,5% de umidade, 0,8% de cinzas, 0,9% de proteínas, 0,01% de lipídios e 87,7% de carboidratos. O ponto isoelétrico encontrado foi de 3,2. A CAA para a GC controle foi no mínimo 50% maior que a da GA em todas as temperaturas avaliadas. Entretanto, apresentou CAO 35% menor, solubilidade 4% menor e consistência inferior. A APD aumentou a solubilidade da GC em 5% a 30°C, 4% a 60°C e 12% a 90°C, e reduziu a CAA em 66% a 30°C, 44% a 60°C e 25% a 90ºC. A APD também reduziu a CAO da GC em 63%. Quanto as características reológicas, o processamento da GC por APD a 30 MPa quando comparada com a GC controle resultou em diminuição do índice de consistência (k) em 69% e elevação do índice de fluxo (n) em 16%, aproximando o comportamento ao fluxo da goma ao de um fluido Newtoniano. O efeito da APD nas emulsões produzidas com GC promoveu redução de 14% no diâmetro médio volumétrico (D4,3) e 17% no diâmetro médio de área superficial (D3,2). O potencial zeta permaneceu constante quando a GC foi processada a 20 MPa, mas reduziu quando processada a 40 MPa. A reologia das emulsões permaneceu constante, já o processamento com APD melhorou a estabilidade da emulsão (menor índice de cremeação e maior turbidez). A turbidez das emulsões aumentou em 25%. Por fim, conclui-se que a GC apresenta boa capacidade de absorção de água, alta solubilidade em água (acima de 80%), baixa capacidade de absorção de óleo e baixa viscosidade aparente mesmo em soluções mais concentradas (20% m/v) quando comparada com a goma arábica. A APD é capaz de modificar as características tecnológicas da GC (solubilidade, CAA, CAO e reologia) e melhorar suas propriedades emulsificantes (menor tamanho médio de partículas, maior turbidez e redução no índice de cremeação)
Abstract: The cashew tree gum (CG) is a product isolated by exudate of cashew tree and has been mentioned as possible replacer to arabic gum in food industry. The dynamic high pressure (DHP) is presented as option to physical modification on polysaccharides to improve their technological properties. Thus, this work aimed to evaluate the effect of DHP on technological properties of CG. The exudate was purified and centesimal composition, zeta potential and rheology of the gum were determined. After that, native CG (without processing-control) and processed at DHP were evaluated in terms of its technological properties (solubility and water absorption capacity (WAC) at 30, 60 and 90ºC, oil absorption capacity (OAC), rheology and emulsifying properties) comparing it with the results obtained from arabic gum (AG). CG presented 10,5% of moisture, 0,8% of ash, 0,9% of proteins, 0,01% of fat and 87,7% of carbohydrates. The isoeletric point encountered was 3,2. The WAC for the control CG was at least 50% higher than AG in all temperatures evaluated. However, it presented lower values regarding to OAC (35%), solubility (4%) and consistency. The DHP increased the solubility of CG in 5% at 30ºC, 4% at 60ºC and 12% at 90ºC, decreased the WAC in 66% at 30ºC, 44% at 60ºC and 25% at 90ºC. The DHP decreased the OAC of CG in 63% as well. In terms of rheological characteristics, the processing of CG by DHP at 30 MPa when compared with control CG resulted in decrease of consistency index (k) with a increment of pressure in 69% and elevation of flow index (n) in 16%, making the behavior to the gum flow closer to the Newtonian fluid. The effect of DHP on CG emulsions resulted in a reduction of 14% on average volumetric diameter (D4,3) and 17% on average superficial area diameter (D3,2). The zeta potential remained constant when the GC was processed at 20 MPa, but decreased when processed at 40 MPa. The rheology of the emulsions remained constant, but the processing with APD improved emulsion stability (lower creaming index and higher turbidity). The turbidity of emulsions increased in 25%. Finally, CG presented good WAC, high solubility (up 80%), low OAC and low apparent viscosity even in more concentrated solutions (20% w/v) when compared with arabic gum. The DHP is capable to modify the technological properties of CG (solubility, WAC, OAC and rheology) and improve their emulsifying properties (lower average particle size and creaming index and higher cloudiness)
