Vertical growth of mini watermelon according to the training height and plant density

A melancia é uma espécie tradicionalmente conduzida em campo no sistema rasteiro. As cultivares de frutos pequenos (1 a 3 kg), que adquirem melhores preços de mercado, vêm sendo cultivadas também em ambiente protegido, onde são conduzidas no sistema vertical, com poda de ramos e raleio de frutos. Essas práticas possibilitam aumentar o adensamento das plantas, a qualidade e a produtividade de frutos em comparação ao sistema rasteiro. Objetivou-se com este trabalho avaliar a influência de três alturas de condução (1,7; 2,2 e 2,7 m) e duas densidades de plantas (3,17 e 4,76 plantas m-2) sobre as características produtivas e qualitativas da mini melancia Smile cultivada em ambiente protegido. A poda da haste principal foi realizada aos 43, 55 e 66 dias após o transplante (DAT) para as alturas de condução de 1,7; 2,2 e 2,7 m, respectivamente. A massa seca dos ramos, dos pecíolos, das folhas e total foram afetados pela altura de condução, cujos maiores valores foram obtidos para as plantas conduzidas a 2,2 e 2,7 m de altura. A área foliar, a área foliar específica e o índice de área foliar não foram influenciados pela altura de condução das plantas. A altura de condução de 2,7 m elevou a produtividade total. Entretanto, a produtividade comercial, a massa média dos frutos e todas as características qualitativas não foram significativamente diferentes das obtidos pela altura de poda de 2,2 m. em relação à densidade de plantas, a melhor opção foi a de 4,76 plantas m-2, pois elevou a produtividade comercial em 37,4% sem reduzir a massa média dos frutos.

Estimativa do número de frutos por amostragem de parte da copa em laranjeiras

Estudou-se um método objetivo para a estimativa do número de frutos em pomares de laranja baseado na contagem dos frutos em ramos de 5 cm de diâmetro. Foram realizados levantamentos em laranjeiras durante três safras, obtendo-se o número de frutos produzidos em um ramo terminal, tomado ao acaso, bem como o número total na árvore. Consideraram-se nove estratos, constituídos pelas cultivares de laranja-doce, Hamlin, Pêra, Natal e Valência (as duas últimas analisadas conjuntamente) e três faixas etárias (três a cinco, seis a 10 e mais que 10 anos de idade). Foram ajustados modelos de regressão linear para o número total de frutos da árvore em função do número de frutos no ramo, obtendo-se coeficientes de determinação variando de 0,79 a 0,94. Com exceção da cultivar Hamlin, verificou-se coincidência entre as curvas das faixas etárias correspondentes. Esses resultados permitem estimar a produção média de frutos em um pomar de laranja, com base em amostragem de ramos com tamanho fixo, com precisão satisfatória, sem o uso de métodos de amostragem mais laboriosos e onerosos.

Efeito de giberelina (GA3) e do bioestimulante 'Stimulate' na indução floral e produtividade do maracujazeiro-amarelo em condições de safra normal

O objetivo do trabalho foi avaliar os efeitos de GA3, nas concentrações de 100; 200 e 300mg L-1 e do bioestimulante Stimulate®, em doses de 2,08; 4,17 e 6,25mL L-1, em duas aplicações via foliar, acrescidas de espalhante adesivo Silwett® a 0,05% e a exposição dos ramos à luminosidade, na indução floral e produtividade do maracujazeiro-amarelo, em condições de safra normal, em Araguari-MG. Aos 30 dias após a primeira aplicação dos tratamentos, iniciaram-se as avaliações do número de flores, com contagens diárias, nos dois lados da espaldeira, nos meses de setembro de 2002 a março de 2003. As colheitas dos frutos foram realizadas semanalmente, no período de novembro de 2002 a abril de 2003, observando-se a produção. O GA3 e o Stimulate não proporcionaram efeito significativo no número de flores, nas sete épocas, assim como no número total de flores. Não houve efeito dos tratamentos para a produtividade e produção total de frutos. Os ramos sob luminosidade pela tarde apresentaram maior número de flores, nos meses de setembro, dezembro, fevereiro e março. A interação entre os tratamentos e a exposição dos ramos à luminosidade não foi significativa para o número de flores, nas épocas avaliadas.

Sociedade civil no espaço de atuação com juventude: uma cartografia social

This report has as its objective the setting up of a social cartography, mapping and characterizing non-governmental organizations working with adolescents and young people (OSC) in the western districts of the city of Natal. Characteristics such as the profile, themes and principal activities, how the organizations fit into the public sector and their participation in social networks are observed. Thus common differences and similarities which serve as a means of indentification, take as reference the symbolic cartography of Boaventura of Sousa Santos. Since there are relatively few studies relating to civil society of Rio Grande do Norte and in particular, Natal, the starting point was the setting up of a database allowing for a general overview. Hence a panorama of the organizations could be observed: where they are located, when they were formed how they operate and their relationships with other sectors (the state, the market and civil society) in addition to basic facts and location. The principal lines of enquiry were a) the OSC which operate with the public comprising adolescents and young people and b) the OSC operating or having branches in four suburbs on the periphery of the western administrative region of the city (Felipe Camarão, Bom Pastor, Cidade Nova and Guararapes).The present report has identified the impacts of ongoing social transformation caused by the process of globalization ,by the various currently contested political projects which are as follows: the project of neoliberal globalized capitalism(hegemonic)and the project of social emancipation (contra-hegemonic),how these are seen from the local viewpoint and how they influence the profiles and operation of the cartographic organizations. The area of the OSC is a heterogenous one with political, cultural and ideological strains, characterized by its infiltration, its local/global and multicultural dimensions. As civil organizations are fundamental in the processes of transformation within society, and following the idea of social emancipation referred to by Boaventura Santos, the enquiry classified the organizations according to the afore-mentioned characteristics, establishing eight types of associations. These different types and their respective characteristics were analysed from a related perspective using the mechanisms of symbolic cartography: scale, projection and symbolisation. The theoretical references underpinning this research arise from the debate on civil society which becomes redefined as a result of the dispute involving the two afore-mentioned political projects. These demand the theoretical application of the comprehension of heterogeneity in its diversity and complexity together with the idea of social emancipation.The main authors consulted were Boaventura de Sousa Santos, Antonio Gramsci, through the texts translated by Marco Aurelio Nogueira; Carlos Nelson Coutinho and Alberto Rivera ,who supported the construction of the types of associations identified by the local reality.Finally this research enabled an understanding of the current form of social action happening in the Space of the Four Neighbourhoods (Espaço dos 4 Bairros) and how the distinct profiles analysed together with the ares of operation of the organizations define their emancipatory potencials within the following two poles: regulation/adaptation and emancipation/transformation

Geostatistical characterization of the spatial distribution of Xylella fastidiosa sharpshooter vectors on citrus

A distribuição espacial das espécies de cigarrinhas (Dilobopterus costalimai Young, Acrogonia sp. e Oncometopia facialis Signoret), vetoras da Xylella fastidiosa, agente causal da Clorose Variegada dos Citros, foi estudada com o uso da geoestatística. As avaliações foram feitas em um pomar comercial de laranja 'Pêra' (Citrus sinensis [L.] Osb.), objetivando estabelecer meios para melhor controle dos vetores e da doença. O monitoramento da ocorrência das cigarrinhas no pomar foi feito através de amostragens mensais, utilizando-se armadilhas adesivas amarelas de 3 x 5, distribuídas uniformemente em 50 pontos na área, dispostas em laranjeiras à altura de 1,5 m do solo e substituídas mensalmente. Acrogonia sp. foi a espécie prevalente nas amostragens. Os resultados possibilitaram ajustar modelos aos semivariogramas da distribuição espacial das três espécies no pomar estudado. Durante os três anos consecutivos de amostragem, as populações de Acrogonia sp., D. costalimai e O. facialis apresentaram modelos de distribuição agregada somente nos meses de verão, inverno e primavera, respectivamente, mostrando a necessidade de monitoramento constante desses vetores para reduzir a sua população em épocas favoráveis ao seu desenvolvimento. Através de parâmetros geoestatísticos foi possível calcular a área de agregação das cigarrinhas no pomar. A espécie Acrogonia sp. apresentou área média de agregação de 15.760 m², enquanto para O. facialis e D. costalimai foi possível constatar áreas médias de agregação de 11.555 m² e 10.980 m², respectivamente. Esses resultados indicaram que para um levantamento seguro de cigarrinhas é necessário pelo menos dispor de uma armadilha por hectare.

Ativismo judicial e materialização das políticas públicas infanto-juvenis na constituição da república: Fixação de planos ideais de atuação para os atores do Sistema de Garantia de Direitos (SGD)

The research arose from the necessity of showing ways to be followed by the actors of the System Guaranteeing Rights of the Child and Adolescent (SGD), regarding the implementation of rights for young people, because the legislation in force in Brazil is currently considered a model around the world and, paradoxically, the fundamental rights of children and adolescents are not met, even with the constitutionally guaranteed priority. Thus, the study investigates the fundamentality rights for young people, enshrined in the Constitution of the Republic, as well as the ways of effectiveness of these rights through the actions of actors of the System Guaranteeing Rights, especially the judiciary. Focusing realized, studying theories of fundamental rights, especially Structuring a Theory of Law (Strukturiende Rechtslehre), Friedrich Müller, who emphasizes the need for analysis of social reality in the application of the rule of law. Study also the public budget and public policies concerning children and adolescents, with emphasis on preparation of budget laws and the process of discussion, deliberation, choice and implementation of public policies for children and teenagers. It then presents the typical functions of the members of System Guaranteeing Rights, as well as prepare a plan for optimum performance for each of the actors, with emphasis on analysis of the implementation of public policies at the municipal level. Finally, it analyzes the theory of separation of three powers, and discusses the positive and negative factors for judicial intervention, concluding that the Courts can consider the action activist, from finding the omission of the Executive and legislative branches, as regards the implementation of the rights of children and adolescents, as well as the rights of children and young people are not realized in most cases, due to the omission of actors of the System Guaranteeing Rights

O direito coletivo prestacional à saúde e o poder judiciário: a concretização do art. 196 da Constituição de 1988 pela via jurisdicional

During the ninth century, owing to the process of industrialization, new social conflicts were showed, forcing the Government not to remain inert. The necessity of answer to these new demands requires from the State some actions that assure the new economic, cultural and social rights, able to exceed the formal equality, according to the principles of redistributive equality and well-being. Among the social rights, the right to health is showed up, which is placed at the Universal Declaration of Human Rights and the International Treaty for the Economic, Social and Cultural Rights, as a necessary term to promote the dignity and the free development of the human personality. Under the Constitutional Law, it is clear that the implementation of the right to health, placed at the 6th article of the Brazilian Constitution, demands a government activity, which usually requires a provision of material goods, depending on budgetary resources. The Legislative and Executive Branches have a very important role in compliance with the constitutional regulations about the satisfactory offer of health care services, besides the correct use of the resources at this area. The adoption of public policies is the way of Government action to the planning and realization of this right. Though, some public policies are usually made apart from the social compromises, to the detriment of the basic social rights. The government has a discretionary competence to manage the health services. That is the reason it is necessary the control of the political choices, through the popular control, the extrajudicial control by the Account Courts, or the judicial review. Owed to the constitutionalization of social rights, the constitutional justice has a very relevant role, concerning to the constitutional jurisdiction, in a way the Judiciary Branch assume your position as a player that transforms the society. On the control of the public health policies, there is a cast of official instruments, judicial or not, to the guarantee of the collective right to the public health services, and to allow the citizens to reach the real implementation of the right to health

Desenvolvimento de Leptoglossus gonagra Fabr. (Heteroptera: Coreidae) em espécies de maracujazeiro

Objetivou-se estudar o desenvolvimento de Leptoglossus gonagra Fabr. (Heteroptera: Coreidae), em cinco espécies de maracujazeiro (Passiflora spp.), discriminando-as quanto aos tipos e graus de resistência. Os ensaios foram conduzidos em laboratório sob condições de 25 ± 1º C; 65 ± 10% UR e fotofase de 14 h, durante 1998, em Jaboticabal, SP. Foram utilizados ramos, botões florais, flores e frutos de P. alata, P. edulis f. flavicarpa, P. giberti, P. laurifolia e P. nitida. Avaliou-se a duração de cada ínstar, a mortalidade em cada ínstar e em toda fase ninfal, o peso de ninfas de terceiro e quinto ínstares com 24 h de idade, o peso de adultos com 24 h de idade e a longevidade. Utilizou-se o delineamento estatístico inteiramente casualizado. em todas as espécies, L. gonagra não completou seu desenvolvimento quando alimentado apenas com frutos. Os ramos, botões florais, flores e frutos de P. nitida apresentaram grau de antibiose mais elevado que os de P. alata, P. edulis f. flavicarpa e P. giberti, enquanto P. laurifolia é a espécie mais adequada ao desenvolvimento de L. gonagra.

O sindicato como espaço de construção da profissão docente

This work examines the connection Syndicate/teachers profession trying to unveil the important role taken over by the Syndical movement in the process of professionalization of the militant teachers. For that, it describes and analyses the historical course of three Syndicates representatives of the teachers category Associação dos Professores Licenciados da Bahia APLB; Sindicato dos Trabalhadores em Educação de Pernambuco SINTEPE; Sindicato dos Servidores Municipais de Petrolina SINDSEMP acting in the micro-region of the San Francisco Valley, especially, in the municipalities of Juazeiro Bahia , and of Petrolina Pernambuco. It concentrates its interests on the contribution of the Syndicates for the professional development of these teachers in this region analysing the aspects related to emerging conflicts into the Syndical organization, to the attitude of these entities before the educational reality to their reinvindicative struggles to the formative dimension of the group actions. This study tries to answer the following questions: How has this syndical movement of teachers of state school of S. Francisco Valley been characterized? How do their actions reflect in the formation and professionalization of the teachers? Do teachers recognize the syndicate as a constructive space for the teaching profession? The methodological trajectory was directed through a qualitative approach of an etnomethodological character, using instruments for the understanding of this reality, The treatment of the data was based on the interpretative analysis of the speeches present in documents and through answers of the interviwees, having as a reference in this analysis the theoretical studies about syndicalism and the teacher professionalization. For a conceptual construction of this work it was studied these two categories from their genesis, from the social historical evolution of their concepts and the up to date discussions that give explanations about the teachers syndical movement and about the process of teachers professionalization. As thesis of this study it was defended the idea of that the teachers syndicates have contributed expressively in the process of the construction of the teacher profession of the militant teachers of this in the micro-region of the S. Francisco Valley. Once the teachers participate actively in this movement promoted by the syndical entities, the teachers develop the critical sense of the educational realty; improve their formation and reinvindicate from the State this condition as a Right; fight for better conditions in the work; reinvindicate the salary valuation and, try to construct an image of teacher basing on a professional model. The contribution of the Syndicate in the process of teachers profissionalization, is more evident in its external dimension that chacterizes the profissionalism, on the related aspects: to the forms of participation in the definition and the management of the educational politics; to the political struggles for the achievements of the professional status, to the recognition and of his eventual valuation. The syndical actions have repercussions with less intensity in the inside dimension that defines the profissionality, in the related aspects: to the administratation of the pedagogical processes in schools and in the classroom; to the acquisition of branches of knowledges; to the epistemological criticism of the acquirements mobilized in the teaching; the curricular question to the mediation that make possible the learning at school and in the classroom

Ocorrência da Mosca-negra-dos-citros (Aleurocanthus woglumi ashby) (Hemiptera: aleyrodidae) em Pernâmbuco

This paper aimed to verify the presence of black-fly of citrus in the state of Pernambuco in Brazil and wordwide. The material with symptoms were collected in the metropolitan area of Recife/PE and subsequently led to the identification in the Insect Biology Laboratory of the Federal Rural University of Pernambuco - UFRPE on February 4, 2011. The samples collected from the branches of citrus and bilocular, found the presence of eggs, nymphs, "pupae" and adults of Aleurocanthus woglumi, confirming its occurrence in the state of Pernambuco. The presence of blackfly of citrus had been detected in the city in the state of Pernambuco as Timbauba, Bom Jardim, Macaparana, Axes, Orobo, Sao Vincent Farrer and Itambe in citrus plants. Before that had a suspect in the Valley Siriji/PE, now it is in the metropolitan area of Recife, therefore we can confirm that the material collected and identified in the metropolitan area of Pernambuco is A. woglumi.

Oviposition of Quesada gigas (Hemiptera: Cicadidae) in coffee plants

Branches of coffee-plant were collected in Sao Sebastiao do Paraiso County, Minas Gerais State, at the Experimental Station of the Agricultural Research Company (Empresa de Pesquisa Agropecuaria de Minas Gerais - EPAMIG), with the aim of studying various aspects of oviposition by Quesada gigas (Hemiptera: Cicadidae). The number of branches with Q. gigas egg nests was analyzed, as well as the number of nests per branch, the eggs per nest and the diameter of the egg nest location on the branch. The preference for oviposition either on alive or dry branches and the size of the egg were assessed. Egg-laying occurred only on dry branches. The mean of the branch diameter on which the egg nests occurred was 2.5 +/- 0.53 mm. The number of eggs per nest averaged 13.2 +/- 4.9, and the number of egg nests per branch was 2.2 +/- 1.74. The eggs were 1.9 +/- 0.08 mm long by 0.5 +/- 0.04 mm wide. The largest diameters of the branches containing egg nests were found on the upper third of the trees, as well as the greatest amount of branches with egg nests, of egg nests per branch and of eggs per nest. The correlation relationship between all of the experiment variables was positive.
