O conhecimento da interferência do porta-enxerto no desenvolvimento da copa é muito importante, pois tais interações para cada combinação porta-enxerto e cultivar copa adotada pode variar. Dessa forma, o objetivo deste trabalho foi avaliar a interferência dos porta-enxertos \'IAC 766\', \'IAC 572\', \'IAC 313\', \'IAC 571-6\' e \'Ripária do Traviú\', no desenvolvimento e fertilidade das gemas da cultivar copa \'Niagara Rosada\'. O estudo foi realizado em videira \'Niagara Rosada\' conduzida sob o sistema de espaldeira, na região de Jundiaí - SP. As avaliações foram realizadas em três ciclos de produção, destes, dois foram realizados no ciclo tradicional, em que a poda de produção é realizada no inverno e a colheita no fim da primavera e início de verão, e um foi realizado na denominada safrinha, em que a poda de produção ocorre no verão e a colheita no fim do outono e início do inverno. Para os ciclos de produção tradicionais avaliou-se a fertilidade da primeira até a quarta ou quinta gema, o número de brotação, o número de cacho e o comprimento final dos ramos em 2014 e 2015. No ciclo de produção safrinha avaliou-se a fertilidade da quinta até a oitava gema e os demais dados biométricos durante o cultivo. Nesse ciclo de produção avaliou-se a produção e qualidade de frutos da videira. O delineamento experimental adotado foi em blocos casualizados em esquema de parcela subdividida para fertilidade de gemas, e em blocos casualizados para as demais variáveis. Os dados coletados foram submetidos à análise de variância, e quando significativo, os dados foram submetidos ao teste de comparação de médias Tukey a 0,05 de probabilidade. Não foi observado efeito dos diferentes porta-enxertos na fertilidade de gemas, no desenvolvimento da planta, na produção e qualidade dos frutos de videira \'Niagara Rosada\'.

Wireless Sensor and Actuator Networks (WSAN) are a key component in Ubiquitous Computing Systems and have many applications in different knowledge domains. Programming for such networks is very hard and requires developers to know the available sensor platforms specificities, increasing the learning curve for developing WSAN applications. In this work, an MDA (Model-Driven Architecture) approach for WSAN applications development called ArchWiSeN is proposed. The goal of such approach is to facilitate the development task by providing: (i) A WSAN domain-specific language, (ii) a methodology for WSAN application development; and (iii) an MDA infrastructure composed of several software artifacts (PIM, PSMs and transformations). ArchWiSeN allows the direct contribution of domain experts in the WSAN application development without the need of specialized knowledge on WSAN platforms and, at the same time, allows network experts to manage the application requirements without the need for specific knowledge of the application domain. Furthermore, this approach also aims to enable developers to express and validate functional and non-functional requirements of the application, incorporate services offered by WSAN middleware platforms and promote reuse of the developed software artifacts. In this sense, this Thesis proposes an approach that includes all WSAN development stages for current and emerging scenarios through the proposed MDA infrastructure. An evaluation of the proposal was performed by: (i) a proof of concept encompassing three different scenarios performed with the usage of the MDA infrastructure to describe the WSAN development process using the application engineering process, (ii) a controlled experiment to assess the use of the proposed approach compared to traditional method of WSAN application development, (iii) the analysis of ArchWiSeN support of middleware services to ensure that WSAN applications using such services can achieve their requirements ; and (iv) systematic analysis of ArchWiSeN in terms of desired characteristics for MDA tool when compared with other existing MDA tools for WSAN.

The instability of environment between years in climates of subtropical regions difficult to obtain peach trees genotypes with wide adaptation and stable production, contributing to poor crop. The climate instability can affect development stages as flower bud and vegetative bud formation. The factors understanding that control the bud formation, presents elementary importance for effective solutions search to these problems. The objective this work is verify the temperature effect, relative humidity and rainfall on bud density and length shoot (Brindilas) and identify genotypes with more adaptability and stability for this character. Was used 12 peach trees genotypes growing in experimental orchard in the Technology Federal of Paraná State University, Campus Pato Branco with Cfa Köppen climate according to the classification. Data of rainfall, hourly temperature were collected by the weather station of Simepar. They were used three plants for genotype (rehearsal), identify five shoots per tree, in May of each year. Were carried analyzes of length shoot CR (cm), count number of flower bud (GF) and vegetative bud (GV). Also calculated the relationship between GF/GV and flower bud density and vegetative bud density. Evaluations were performer annual 2007-2014. With these data adaptability and stability analyzes were performed using Biplot methodology and correlations analyzes (Pearson) with climates variables. They used the weather data to calculate the sums of hours with temperatures below 20 °C, temperatures between 20-25 °C, temperature between 25-30 °C and temperature above 30 °C, considering the period of August 1fst of the previous period to February 28 of the following year. Pearson correlation coefficients were used for path analysis, GF and DGF as basic variables. For CR, GV and GF the highest average occurred in 2009/10 period. The genotypes ‘BRS Kampai’ and ‘BRS Libra’ highest CR. They are considered stable and adapted as the CR genotypes ‘Casc. 967’ and ‘BRS Kampai’. There was negative correlation between CR and GV for Σh <20 ° C, Σh> 30 °C and Σh with URA <50% and positive correlation between these variables and Σh 25-30 °C and Σh with URA> 70%. The evaluation of GV ‘Cons. 681’ and ‘Casc. 1055’ can be considered adapted and stable. The lowest average was presented by the genotype ‘Sta. Áurea’ though the genotype is also stable. In GF evaluation genotypes are considered adapted ‘BRS Bonão’, ‘Casc. 1055’, ‘Cons. 681’ with adaptability to all evaluated period. In path analysis was direct effect Σh 25-30 °C on flower bud density. In evaluating DGV and DGF and the variations are due to genetic effect. The most adapted and stable genotypes for DGV were ‘T. Beauty’, ‘T. Snow’, ‘Casc. 1055’ and ‘Cons. 681’. CR and GV variables are strongly affected by environment. GF is strongly affected by genetic conditions and moderately affected by environment. DGV and DGF are affected basically by genetic conditions.

Os níveis de concentração de CO2 atmosférico estão se elevando nas últimas décadas devido principalmente à queima de combustíveis fósseis. Essa alteração atmosférica, além de intensificar o fenômeno do efeito estufa, pode afetar o comportamento de algumas plantas e microrganismos de interesse agrícola. O CO2. por ser um componente básico da fotossíntese, em alta concentração, pode causar alterações na morfologia e nos processos fisiológicos das plantas, assim como na interação destas com fitopatógenos. Sendo assim, o presente estudo teve por objetivo avaliar o efeito da alta concentração de CO2 atmosférico na severidade do oídio, causado por Microsphaera diffitsa, e da ferrugem asiática, causado por Phakopsora pachyrhizi, na soja e também em alguns fatores relacionados ao desenvolvimento da planta que podem exercer influência na doença. como o crescimento, peso da matéria seca e nodulação. Foram realizados três ensaios em estufas de topo aberto com (E+CO2) ou sem (E) injeção de CO2 e sem estufa (T), correspondendo às concentrações de, aproximadamente, 647 ppm, 474 ppm e 453 ppm, respectivamente. No primeiro ensaio, foram avaliadas características de desenvolvimento da planta; no segundo, a severidade da ferrugem asiática, que ocorreu de Confia espontânea; e no terceiro, a severidade do oídio em quatro cultivares com diferentes níveis de resistência. As cultivares foram: FT-Estrela, altamente suscetível (AS); Embrapa 48, suscetível (S); FT-Cometa. moderadamente resistente (MR) e FT-5 (Formosa), resistente (R). Nos resultados obtidos, foi verificado um aumento significativo na severidade do oídio, no tratamento com injeção de CO2,em folhas primarias e na planta inteira das cultivares analisadas em conjunto. mas não houve alteração na expressão de resistência das cultivares. Para a ferrugem asiática, houve redução da severidade da doença com injeção do gás. A esporulação de ambos os patógenos não sofreu efeito no ambiente com injeção de CO. O efeito do CO2 incrementou o crescimento e a nodulação das plantas, de modo geral: no entanto, o peso da matéria seca não se alterou significativamente. O CO2 em altas concentrações na atmosfera pode alterar a severidade de doenças e, assim sendo, as estratégias de manejo fitossanitário da cultura.
