“…An increased budding can be regarded as important for orchid trade since the numbers of leaves and flowers are directly related to the number of buds. Similar results were observed for orchids of the species Cattleya intermedia and C. loddigesii (SCHNITZER et al, 2010), thus increasing the number of sprouts what directly reflects on flower numbers. The results obtained with C. loddigesii also demonstrate that pyroligneous extract use in propagation substrates can favor seedling production (SCHNITZER et al, 2015).…”

-Pyroligneous fraction from wood carbonization can be used for several purposes. In this sense, this study aimed to test a pyroligneous liquor extracted during carbonization of forest residues for the vegetative development of the orchid Oeceoclades maculata. The concentrations of pyroligneous liquor used in the treatments were T1 = 0 mL L . These treatments were tested together with and without activated charcoal for in vitro and ex vitro propagation. In vitro developed protocorms were assessed according to development or not, the presence of fungus, leaves, and roots. For ex vitro evaluations, leaf size, size, the number of roots, total plant height, and the number of buds were assessed. Possible differences between treatments were tested by means of analysis of variance (ANOVA) and Tukey's test at 5% significance. The use of pyroligneous liquor at low doses was significant in vegetative tissue development as well as for root and leaf formations in O. maculata seedlings since it presents all the essential mineral elements to the structural development of these plants.

Lindl.RESUMO -A fração pirolenhosa obtida com a carbonização da madeira pode ser utilizada para diversos fins. Sendo assim, este trabalho teve por objetivo testar o licor pirolenhoso extraído durante o processo de carbonização de resíduos florestais no desenvolvimento vegetativo da orquídea Oeceoclades maculata. As concentrações do licor pirolenhoso utilizadas nos tratamentos foram: T1 = 0 ml.L -1 , T2 = 1 ml.L -1 , T3 = 2 ml.L -1 , T4 = 3 ml.L -1 , T5 = 4 ml.L -1 e T6 = 5 ml.L -1 , esses tratamentos foram testas com e sem carvão ativado no desenvolvimento in vitro e ex vitro da orquídea. As seguintes características dos protocórmos desenvolvidos in vitro foram avaliadas: com fungo, sem desenvolvimento, em desenvolvimento, presença de folhas e raízes. Para o desenvolvimento ex vitro foram avaliados: Tamanho das folhas, tamanho e número de raízes, altura total da planta, quantidade de gemas. Possíveis diferenças entre os tratamentos foram testada por meio de Análise de variância (ANOVA) e teste de Tukey a 5% de significância. O uso do licor pirolenhoso em dosagem pequenas mostrou-se significativo no desenvolvimento dos tecidos vegetativos e na formação radicular e foliar de Oeceoclades maculata, uma vez que apresenta todos os elementos minerais essenciais ao desenvolvimento estrutural da planta.Palavras-Chave: Orquídea.

“…Research conducted with farmers in Japan using pyroligneous extract found its action as repellent for some species of pests in crops, such as birds, bats and rodents, its benefit in preventing disease in crops, action on animal feces in order to eliminate the strong odor (ENCARNAÇÃO, 2001), improving the vegetative development of some crops, organic fertilization, soil conditioning and to facilitate the rooting of certain plant crops (SCHNITZER et al, 2015).…”

Water is the main input used in shrimp farming, and the good quality of this natural resource is not only essential for the farmed animals' welfare, but also for a good profitability at the end of the farming process inaquaculture species. Pyroligneous extract (PE) is a yellow to reddish-brown liquid obtained from the condensation of gases produced by partial wood combustion. This compound has been used for several purposes in different areas, such as in the fertilization of various vegetable crops and in soil conditioning. The objective of the present study was to evaluate the possible benefits of the application of pyroligneous extract on water quality and its consequences on the production performance of Penaeus vannamei. Six 1.0 ha ponds were used, 3 of which were used for the application of pyroligneous extract (WPE) and the other 3 without the extract (wPE) for comparison purposes. The extract was diluted in water and applied directly to the dry soil and after a few hours of reaction the ponds were filled with water and prepared for cultivation. There was a significant difference (p<0.05) between the ponds (WPE) and (wPE) in the following water quality parameters: dissolved oxygen, pH, total alkalinity, total hardness, magnesium and silica. However, the values found

“…In Brazil, there are references to several initiatives aiming at consolidating this practice, however, the shortage of studies on the potential of the pyroligneous has not been sufficiently explored, which would allow a wide dissemination of its use. An example of this would be the uses in the preservative treatment of woods, organic fertilizers, soil conditioners, rooting aids and organic insecticide (SCHNITZER et al, 2015). In practical terms, in addition to reducing the emission of gases to the atmosphere, the collection, separation and commercialization of the pyroligneous from the pyrolysis process can further provide the producer with additional income, besides the charcoal.…”

ResumoEste estudo teve por objetivo analisar a madeira de dez espécies endêmicas da região do semiárido brasileiro, sobretudo quando submetida à pirólise e caracterização do extrato pirolenhoso. Na madeira foram analisados os teores de extrativos totais, lignina e cinzas, poder calorífico e a composição química elementar (C, H, O, N, S). Amostras foram submetidas ao processo de pirólise flash sob uma temperatura de 500 °C com um tempo de permanência de 5 minutos. Os rendimentos em carvão vegetal, líquido pirolenhoso e gases não condensáveis foram determinados. Os extratos de líquidos pirolenhosos foram analisados por meio de cromatografia a gás (GC/MS) com o intuito de detecção de compostos orgânicos. A madeira das espécies Mimosa tenuiflora e Poincianella pyramidalis mostraram-se as mais indicadas para uso de biomassa para energia e para a produção de carvão vegetal em função dos seus elevados teores de lignina, rendimentos em carvão e líquido pirolenhoso. Detectou-se nos extratos pirolenhosos compostos oxigenados, como ácidos carboxílicos, ésteres, éteres e cetonas, além de fenóis, guaiacóis e derivados fenólicos.Palavras-chave: energia da biomassa; líquido pirolenhoso; cromatografia gasosa. AbstractThe objective of this study was to analyze wood from ten species, endemic of the Brazilian semi-arid region, especially when subjected to pyrolysis and characterization of pyroligneous extract. In the wood, the total extractive, lignin and ash contents, the calorific value, and the elementary chemical composition (C, H, O, N, S) were analyzed. Samples were subjected to the flash pyrolysis process at a temperature of 500 °C with a residence time of 5 minutes. The yields of charcoal, pyroligneous liquid, and non-condensing gases were determined. Pyroligneous liquid extracts were analyzed through gas chromatography (GC/MS) with the objective of detecting organic compounds. The wood of the Mimosa tenuiflora and Poincianella pyramidalis species was the most suitable for using biomass for energy purposes and to produce charcoal due to its high lignin content, charcoal yields and pyroligneous liquid. Oxygenated compounds, such as carboxylic acids, esters, ethers and ketones, as well as phenols, guaiacols and phenolic derivates were detected in the pyroligneous extracts.
