Resumo: | The aim of this study was to improve the final quality of the seedlings of yellow passion fruit by adding silicon to the substrate and check the silicon accumulation by the plants. The experiment was conducted in a greenhouse located at the Department of Agriculture, Federal University of Lavras (UFLA). Passion fruit seeds (Passiflora edulis Sims. F. Flavicarpa Deg.) were sown in polystyrene trays until sized reached enough to be transplanted to pots. After 60 days the seedlings with about 15 cm of tall were transplanted in a plastic pots containing 1.1 kg of Tropstrato® substrate. The seedlings randomly arranged on the counter in greenhouse were irrigated daily in order to supplement their water needs. The treatments consisted of four concentrations (0, 0.28, 0.55 and 0.83 g / pot) of silicon in the form of silicic acid solution (SiO2.XH2O) 1%. This solution was applied around the stems of the plants (drench), the first application were at 15 days after the seedlings transplanting. In total were realized three applications with intervals of 15 days. The pots that constituted the control treatment received water in the same amount. After the last application, the plants were subjected to chemical analysis of silicon concentration, X-ray microanalysis, flow cytometry, anatomy, photosynthetic activity, ultrastructural characteristics and analysis phytotechnical. It can be concluded that silicon provides better growth and development of seedlings, concentrations between 0.28 and 0.55 g / pot, the silicon absorption and deposition in passion fruit leaves are proportional to the availability of this element for the plant and plant genetic stability is preserved in the passion fruit treated with silicon Furthermore, this element provides anatomical changes, such as increasing the thickness of the adaxial epidermis and the reduction of palisade parenchyma, also interfering in the photosynthetic apparatus of plants. |

O experimento foi desenvolvido em casa de vegetação, localizada no Departamento de Agricultura, da Universidade Federal de Lavras (UFLA). Sementes de maracujazeiro (Passiflora edulis Sims. f. flavicarpa Deg.) foram semeadas em bandejas de poliestireno até que atingissem porte suficiente para serem transplantadas para vasos. Após 60 dias, as mudas com aproximadamente 15 cm de altura, foram transplantadas para vasos de polietileno contendo 1,1 kg de substrato Tropstrato®. As mudas dispostas aleatoriamente sobre a bancada da casa de vegetação foram irrigadas diariamente, a fim de suprir suas necessidades hídricas. Os tratamentos consistiram de quatro concentrações (0; 0,28; 0,55 e 0,83 g/vaso) de silício na forma de solução de ácido silícico (SiO2.XH2O) a 1%. Esta solução foi aplicada ao redor do caule das plantas (drench), sendo a primeira aplicação realizada 15 dias após o transplantio das mudas. No total, foram realizadas três aplicações, em intervalos de 15 dias. Os vasos que constituíram o controle (testemunha) receberam água na mesma quantidade. Após a última aplicação, as plantas foram submetidas a análise química de concentração de silício, microanálise de raios X, citometria de fluxo, anatomia, atividade fotossintética, características ultraestruturais e às análises fitotécnicas. Pode-se concluir que o silício proporciona melhor crescimento e desenvolvimento das mudas de maracujazeiro, entre as concentrações 0,28 e 0,55 g/vaso, a absorção de silício e sua deposição nas folhas de maracujazeiro são proporcionais a disponibilidade desse elemento para a planta, e a estabilidade genética, é preservada nas plantas de maracujazeiro tratadas com silício. Além disso, este elemento proporciona alterações anatômicas, como o aumento da espessura da epiderme adaxial e a redução do parênquima paliçádico, interferindo também no aparato fotossintético das plantas.UNIVERSIDADE FEDERAL DE LAVRASDAG - Departamento de AgriculturaUFLABRASILDias, Gabrielen de Maria GomesPasqual, MoacirAlvarenga, Ângelo AlbericoPio, Leila Aparecida SallesSouza, Bárbara Nogueira de2015-04-24T17:17:25Z2015-04-24T17:17:25Z2015-04-242015-03-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfSOUZA, B.
