SEEDLINGS PRODUCTION OF UMBUZEIRO ( Spondias tuberosa Arruda C\ue2mara) IN DIFFERENT SUBSTRATES AND SIZE OF BAGS

A esp\ue9cie Spondias tuberosa Arr. Cam. (umbuzeiro) destaca-se como uma das esp\ue9cies arb\uf3reas de maior potencial do semi\ue1rido brasileiro. Apesar de sua relevante import\ue2ncia socioecon\uf4mica e ambiental, h\ue1 falta de estudos voltados para o estabelecimento de um modelo de produ\ue7\ue3o de mudas da esp\ue9cie. O objetivo desse trabalho foi avaliar a produ\ue7\ue3o de mudas de Spondias tuberosa utilizando diferentes substratos e tamanho de recipientes. O experimento foi conduzido no viveiro do Laborat\uf3rio de Ecologia Vegetal (LEV) do Centro de Ci\ueancias Agr\ue1rias (CCA) da Universidade Federal da Para\uedba (UFPB), Areia - PB. O delineamento experimental usado foi em blocos casualizados em esquema fatorial 2 x 7 e parcelas subdivididas, sendo que os recipientes representaram as parcelas e os substratos as subparcelas. Foram utilizados substratos formulados a partir da mistura de terra de subsolo (37,5-100%), areia lavada (12,5- 25%) e esterco bovino curtido (10-50%). Os recipientes utilizados foram sacos de polietileno preto com volumes de 1900 cm3 (15 x 27 cm) e 5000 cm3 (25 x 26 cm). Para a obten\ue7\ue3o das pl\ue2ntulas, sementes de Spondias tuberosa foram semeadas em sementeira de alvenaria at\ue9 a repicagem (90 dias ap\uf3s o semeio). Aos 78 dias, ap\uf3s a repicagem, as mudas foram avaliadas quanto \ue0 altura, di\ue2metro do colo, rela\ue7\ue3o altura/ di\ue2metro do colo, di\ue2metro do xilop\uf3dio, comprimento de raiz, massa seca da parte a\ue9rea e raiz. Os dados obtidos foram submetidos \ue0 an\ue1lise de vari\ue2ncia e ao teste F, sendo as m\ue9dias comparadas pelo teste de Tukey ao n\uedvel de 5% de probabilidade, utilizando o software SISVAR\uae. Os substratos com esterco bovino curtido proporcionaram os maiores valores em altura e comprimento de raiz. Para a produ\ue7\ue3o de mudas de Spondias tuberosa, \ue9 recomendado o substrato contendo terra de subsolo (45%) + Areia (15%) + Esterco bovino (40%).The species Spondias tuberosa Arr. Cam. (umbuzeiro) stands out as one of the tree species with the greatest potential of the Brazilian semiarid. Even though it\u2019s significant socioeconomic and environmental importance, there is a lack of studies aimed at establishing a seedlings production model of this kind of plant. The purpose of this study was to evaluate the production of seedlings Spondias tuberosa using different substrates and size of bags. The experiment was conducted in the nursery of the Plant Ecology Laboratory (LEV) from the Agrarian Sciences Center (CCA) of the Federal University of Paraiba (UFPB), Areia/ PB. The experimental design was a randomized block in factorial 2 x 7 and subdivided blocks containersplots and subplots substrates. It were used substrates formulated from the starting mixture of subsoil land (37.5-100%), sand (12.5-25%) and tanned cattle manure (10-50%). The containers used were black polyethylene bags with a volume of 1900 cm3 (15 x 27 cm) and 5000 cm3 (25 x 26 cm). To obtain seedlings of Spondias tuberosa seeds were sown in seed masonry until the transplant (90 days after sowing). At 78 days after transplanting the seedlings were evaluated for height, root collar diameter, relationship shoot/root collar diameter, xylopodium diameter, root length, dry weigh of shoot and root. The datas were subjected to analysis of variance and F test, measured and compared by Tukey test at 5% probability, using the software SISVAR\uae. The substrates with cattle manure provided higher values for height and root length. For the seedlings production of Spondias tuberosa, is recommended substrate subsoil land (45%) + sand (15%) + cattle manure (40%)

SALT STRESS ON THE PHYSIOLOGICAL QUALITY OF Cryptostegia madagascariensis Bojer ex Decne. SEEDS

A esp\ue9cie Cryptostegia madagascariensis Bojer ex Decne. foi introduzida no Brasil com fins ornamentais, mas, atualmente, \ue9 uma invasora do bioma Caatinga. Apesar de sua elevada capacidade de ocupa\ue7\ue3o de \ue1reas alteradas do referido bioma, h\ue1 car\ueancia de informa\ue7\uf5es sobre esta esp\ue9cie, particularmente em rela\ue7\ue3o \ue0 capacidade de suas sementes germinarem em condi\ue7\uf5es adversas. O objetivo deste trabalho foi avaliar a germina\ue7\ue3o de sementes e o crescimento inicial de pl\ue2ntulas de Cryptostegia madagascariensis em fun\ue7\ue3o da salinidade em diferentes temperaturas. O experimento foi realizado seguindo um delineamento inteiramente casualizado, com os tratamentos distribu\ueddos em esquema fatorial 6 x 3, sendo seis n\uedveis de salinidade promovidos pelo cloreto de s\uf3dio (NaCl): 0,0 (controle); 2,0; 4,0; 6,0; 8,0 e 10,0 dS m-1; e tr\ueas temperaturas: 25 e 30\ub0C constantes e alternada de 20-35\ub0C. A qualidade fisiol\uf3gica das sementes foi avaliada pelas seguintes vari\ue1veis: germina\ue7\ue3o, primeira contagem e \uedndice de velocidade de germina\ue7\ue3o, comprimento e massa seca de ra\uedzes e do hipoc\uf3tilo. Os resultados obtidos indicam que h\ue1 elevada probabilidade de germina\ue7\ue3o de sementes de Cryptostegia madagascariensis submetidas a estresse salino em temperatura constante de 30\ub0C e alternada de 20-35\ub0C, o que potencializa o seu car\ue1ter invasor.The Cryptostegia madagascariensis Bojer ex Decne. species was introduced in Brazil with ornamental purposes, but currently, it is invasive in the Caatinga biome. Despite its high level of occupancy of altered areas of Caatinga, there is lack of information about this species, particularly in relation to the capacity of its seeds to germinate in adverse conditions. The objective of this study was to evaluate seed germination and the initial seedling growth of Cryptostegia madagascariensis in function of salinity at different temperatures. The experiment was conducted following a completely randomized design, with treatments arranged in a 6 x 3 factorial design with six salinity levels promoted by sodium chloride (NaCl): 0.0 (control); 2.0; 4.0; 6.0; 8.0 and 10.0 dS m-1 and three temperatures: 25 and 30\ub0C constant and alternating 20-35\ub0C. The physiological quality of seeds was evaluated using the following variables: germination, first count and the speed of germination index, length and dry weight of roots and hypocotyl. The results indicate that there is high probability of seed germination of Cryptostegia madagascariensis subjected to salt stress at constant temperature of 30\ub0C and alternating 20-35\ub0C, which enhances its invasive character

Conservation of marizeiro Geoffroea spinosa Jacq. seeds using different packagings and environments

O marizeiro ( Geoffroea spinosa Jacq.) \ue9 uma esp\ue9cie florestal importante, sobretudo por ser adaptada \ue0s condi\ue7\uf5es de matas ciliares do semi-\ue1rido e ecossistemas associados, ocorrendo em vastas \ue1reas do Nordeste brasileiro e no vale do rio S\ue3o Francisco, sempre restrita a ambientes sazonalmente inundados. Este trabalho teve como objetivos avaliar o efeito de diferentes tipos de embalagens e do per\uedodo de armazenamento sobre o processo germinativo e o vigor de sementes de Geoffroea spinosa Jacq. acondicionadas tamb\ue9m em diferentes ambientes. O experimento foi instalado no Laborat\uf3rio de Ecologia Vegetal do CCA/UFPB, seguindo um delineamento inteiramente casualizado. As sementes foram distribu\ueddas em dois ambientes (condi\ue7\uf5es naturais, no laborat\uf3rio e c\ue2mara fria), acondicionadas em dois tipos de embalagens (sacos de papel e sacos pl\ue1sticos) durante cinco per\uedodos de armazenamento: 0, 15, 30, 60 e 90 dias. Foram avaliados o teor de \ue1gua, o \uedndice de velocidade de emerg\ueancia, a massa seca e o comprimento de pl\ue2ntulas. Os dados foram submetidos \ue0 an\ue1lise de regress\ue3o polinomial. Na embalagem pl\ue1stica e no ambiente de c\ue2mara fria, houve menor redu\ue7\ue3o da viabilidade e do vigor ao longo do armazenamento. As sementes acondicionadas em sacos de papel e armazenadas em ambiente de laborat\uf3rio perderam rapidamente a viabilidade e o vigor a partir dos 30 dias de armazenamento.Geoffroea spinosa Jacq., commonly known as marizeiro in Brazil, is an important tree species, mainly because it is adapted to riparian forest conditions in semi-arid and associated ecosystems. The species occur in large areas of northeastern Brazil and in the S\ue3o Francisco river valley, always restricted to seasonally flooded environments. This study aimed to evaluate the effect of different types of packaging and storage periods, as well the influence of environments on the process of seed germination and vigor of Geoffroea spinosa. The experiment was carried out at the Laboratory of Plant Ecology - CCA/UFPB, following a completely randomized design. The seeds were distributed among two environments (natural conditions in the laboratory and cold room), packed in two types of packaging (paper bags and plastic bags) for five periods of storage: 0; 15; 30; 60 and 90 days. Water content, the emergence velocity index, dry weight and length of seedlings were evaluated. The data were submitted to a polynomial regression analysis. In plastic packaging and the environment of the cold room there was less reduction of viability and vigor during storage. Seeds packed in paper bags and stored in a laboratory rapidly lost viability and vigor, after 30 days of storage

A tetravalent dengue nanoparticle stimulates antibody production in mice

<p>Abstract</p> <p>Background</p> <p>Dengue is a major public health problem worldwide, especially in the tropical and subtropical regions of the world. Infection with a single <it>Dengue virus </it>(DENV) serotype causes a mild, self-limiting febrile illness called dengue fever. However, a subset of patients experiencing secondary infection with a different serotype progresses to the severe form of the disease, dengue hemorrhagic fever/dengue shock syndrome. Currently, there are no licensed vaccines or antiviral drugs to prevent or treat dengue infections. Biodegradable nanoparticles coated with proteins represent a promising method for in vivo delivery of vaccines.</p> <p>Findings</p> <p>Here, we used a murine model to evaluate the IgG production after administration of inactivated DENV corresponding to all four serotypes adsorbed to bovine serum albumin nanoparticles. This formulation induced a production of anti-DENV IgG antibodies (p < 0.001). However, plaque reduction neutralization assays with the four DENV serotypes revealed that these antibodies have no neutralizing activity in the dilutions tested.</p> <p>Conclusions</p> <p>Our results show that while the nanoparticle system induces humoral responses against DENV, further investigation with different DENV antigens will be required to improve immunogenicity, epitope specicity, and functional activity to make this platform a viable option for DENV vaccines.</p

Trata-se de um estudo prospectivo, n?o concorrente, utilizando dados de pacientes identificados por relacionamento determin?stico- probabil?stico nos registros dos sistemas de informa??o do SUS. Foram inclu?dos 47.079 pacientes que iniciaram em hemodi?lise no per?odo de 1o de janeiro de 2000 a 31 de dezembro de 2003, acompanhados at? a soroconvers?o ou o t?rmino do estudo em 2004. Nesta pesquisa, 3% dos pacientes em hemodi?lise apresentaram soroconvers?o para anti-HCV (incid?ncia de 1,7 soroconvers?o por 100 pacientes/ano). Maior risco de soroconvers?o para o anti-HCV foi associado com idade, glomerulonefrites, regi?o de resid?ncia, anti-HIV positivo e efeito da unidade de di?lise. A incid?ncia observada de soroconvers?o para anti-HCV foi semelhante ? registrada em alguns pa?ses desenvolvidos, destacando-se a evid?ncia de transmiss?o entre os pacientes em hemodi?lise

Structuring of Bacterioplankton Diversity in a Large Tropical Bay

Structuring of bacterioplanktonic populations and factors that determine the structuring of specific niche partitions have been demonstrated only for a limited number of colder water environments. In order to better understand the physical chemical and biological parameters that may influence bacterioplankton diversity and abundance, we examined their productivity, abundance and diversity in the second largest Brazilian tropical bay (Guanabara Bay, GB), as well as seawater physical chemical and biological parameters of GB. The inner bay location with higher nutrient input favored higher microbial (including vibrio) growth. Metagenomic analysis revealed a predominance of Gammaproteobacteria in this location, while GB locations with lower nutrient concentration favored Alphaproteobacteria and Flavobacteria. According to the subsystems (SEED) functional analysis, GB has a distinctive metabolic signature, comprising a higher number of sequences in the metabolism of phosphorus and aromatic compounds and a lower number of sequences in the photosynthesis subsystem. The apparent phosphorus limitation appears to influence the GB metagenomic signature of the three locations. Phosphorus is also one of the main factors determining changes in the abundance of planktonic vibrios, suggesting that nutrient limitation can be observed at community (metagenomic) and population levels (total prokaryote and vibrio counts)

Selection of lettuce genotypes for protected cultivation: genetic divergence and importance of characters

Os objetivos deste trabalho foram selecionar gen?tipos de alface com potencial para cultivo em ambiente protegido; selecionar gen?tipos divergentes geneticamente para integrar programas de melhoramento; comparar t?cnicas multivariadas a fim de se ter uma interpreta??o mais precisa dos resultados; verificar a relev?ncia dos caracteres avaliados para a diverg?ncia gen?tica; e determinar os caracteres mais importantes na avalia??o de gen?tipos de alface. Utilizou-se o delineamento em blocos casualizados, com 15 gen?tipos, quatro repeti??es e 15 plantas por parcela. O experimento foi conduzido em ambiente protegido e avaliou-se a altura das plantas, di?metro da cabe?a, circunfer?ncia da cabe?a, mat?ria fresca da parte a?rea, mat?ria fresca comercial da parte a?rea, mat?ria fresca da raiz, mat?ria seca comercial da parte a?rea, mat?ria seca da raiz e n?mero de folhas comerciais. Os gen?tipos foram classificados em quatro grupos pelo m?todo Tocher. Foram indicados para uso em cultivo protegido e em programas de melhoramento para obten??o de cultivares adaptadas a essas condi??es, as cultivares 'Regina 500'e 'Vit?ria de S. Ant?o' (grupo I), 'Black Seed Simpson' e 'L?via' (grupo II), 'Branca Boston' (grupo III) e 'Romana Bal?o' (grupo IV). Embora a contribui??o relativa da circunfer?ncia para a diverg?ncia seja apenas 0,50%, todas as caracter?sticas avaliadas foram importantes no estudo da diverg?ncia gen?tica. De acordo com o estudo da correla??o genot?pica, a avalia??o da caracter?stica massa fresca da parte a?rea pode substituir a avalia??o das caracter?sticas massa fresca e massa seca comercial da parte a?rea em um processo de sele??o, reduzindo tempo e custo em um programa de melhoramento.Funda??o de Amparo ? Pesquisa do Estado de Minas Gerais (FAPEMIG)Empresa de Pesquisa Agropecu?ria de Minas Gerais (EPAMIG)Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq)Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES)The objectives of this study were to select lettuce genotypes with potential for cultivation in protected environments; select genetically divergent genotypes to integrate breeding programs; compare multivariate analysis to have a more precise interpretation of the results; verify the relevance of evaluated traits to genetic divergence; and determine the most important characters in the evaluation of lettuce genotypes. Fifteen genotypes were studied in a randomized block design with four replications and 15 plants per plot. The experiment was carried out in protected environments and the following traits were evaluated: plant height, head diameter; head circumference; fresh matter of heads; marketable fresh matter of heads; root fresh matter; dry matter of commercial heads; dry matter of roots and number of commercial leaves. The genotypes were classified in four groups by Tocher's method. The genotypes that should preferably be used in protected environment and in breeding programs were 'Regina 500' and 'Vit?ria de S. Ant?o', from group I; 'Black Seed Simpson' and 'L?via' from group II; 'Branca Boston' from group III and 'Romana Bal?o' from group IV. Although the relative contribution of the head circumference is only 0.50%, all traits were important in the study of genetic diversity. According to the genotypic correlation study, the assessment of the fresh mass characteristic of the aerial part can substitute the evaluation of commercial fresh and dry mass of the aerial part in the selection process, reducing the time and cost in a breeding program
