Abstract: Objetivou-se avaliar a influência de níveis de adubos organicos bovino e avícola no teor de clorofila e características anat micas de folhas de plantas de orégano cultivadas em casade- vegeta o. Foram conduzidos dois ensaios separadamente, sendo um com esterco bovino e ooutro com esterco de aves. Plantas de orégano (Origanum vulgare L.) foram cultivadas em vasos de 10 L, submetidas aos seguintes tratamentos: Ensaio I: esterco bovino: 1) solo sem aduba o(controle); 2) solo + 3,0 kg m-2 de esterco bovino; 3) solo + 6,0 kg m-2 de esterco bovino; 4) solo + 9,0 kg m-2 de esterco bovino; 5) solo + 12,0 kg m-2 de esterco bovino; Ensaio II – esterco avícola: 1) solo sem aduba o (Controle); 2) solo + 1,5 kg m-2 de esterco de galinha; 3) solo + 3,0 kg m-2 de esterco de galinha; 4) solo + 4,5 kg m-2 de esterco de galinha e 5) solo + 6,0 kg m-2 de esterco de galinha. Os ensaios foram conduzidos no delineamento experimental em blocos casualizados, com quatro repeti es, e a parcela experimental foi composta por quatro vasos. Observou-se que os níveis de esterco bovino e de aves influenciaram o teor de clorofila e características anat micas das folhas de orégano. This study was performed to evaluate the effect of different levels of cattle and chicken manure organic fertilization in thechlorophyll content and anatomic parameters of leaves of Origanum vulgare L. cultivated in greenhouse. Two assays were carried out separately, one with cattle manure and the other with chicken manure. Origanum vulgare L. plants were cultivated in 10 L pots with the following treatments: Trial I: Cattle manure: 1) Soil without fertilization (control); 2) Soil + 3.0 kg m-2 of cattle manure; 3) Soil + 6.0 kg m-2 of cattle manure; 4) Soil + 9.0 kg m-2 of cattle manure; 5) Soil + 12.0 kg m-2 of cattle manure; Trial II: Chicken manure: 1) Soil without fertilization (Control); 2) Soil + 1.5 kg m-2 of chicken manure; 3) Soil + 3.0 kg m-2 of chicken manure; 4) Soil + 4.5 kg m-2 of chicken manure and 5) Soil + 6.0 kg m-2 of chicken manure. Both trials were carried out in randomized blocks with 4 repetitions and 4 pots per experimental parcel. It was observed thatthe levels of organic fertilization significantly influenced the chlorophyll content and anatomic parameters of wild marjoran leaves.

Abstract: Com o objetivo de avaliar o efeito do meio de cultura no teor e composi o química do óleo essencial de Melissa officinalis, foi realizado o presente trabalho, que avaliaram três concentra es do meio de cultura MS. O experimento foi implantado em delineamentointeiramente casualizado, com sete repeti es, e cada repeti o foi representada por uma amostra de 20 g de plantulas frescas. A extra o do óleo foi realizada em aparelho de Clevenger modificado com dura o de 1h e 30 min. e a análise química foi realizada por cromatografiagasosa. Observou-se que o teor e a composi o química do óleo essencial de M. officinalis foram influenciados pela concentra o de sais do meio MS. As plantulas que se desenvolveram nos meios MS e MS/4 apresentaram maior teor de óleo essencial, e os componentes majoritários foram o geranial (25,23 e 16,21%, respectivamente) e o neral (24,5 e 20,53%, respectivamente). Já o componente majoritário presente no óleo de plantulas de melissa cultivadas em meio MS/2 foio acetato de nerila (18,69%). The present work was carried out with the objective of evaluating the effect of the culture medium in the content and chemical composition of the essential oil of Melissa officinalis, evaluating three concentrations of the MS culture medium. The experiment was performed in a completely randomized design, with 7 repetitions, where each repetition was represented by 20 g of fresh biomass. Oil extraction was accomplished using a Clevenger modified device for 1 hour and 30 minutes, and the chemical analysis was accomplished by gas chromatography. It was observed that the content and chemicalcomposition of the essential oil of M. officinalis was influenced by the concentration of MS medium. The plants grown in the MS medium and MS/4 presented higher content of essential oil, and the major components of these plants were geraniol (25.23 and 16.21%, respectively) and nerol (24.5 and 20.53%, respectively). The major component present in the oil of melissa plants cultivated in MS/2 was neryl acetate (18.69%).

Abstract: Neste presente trabalho, avaliou-se o potencial do carv o ativado, filtro amarelo e a intera o fotoperíodo/temperatura na forma o de estruturas semelhantes a raízes tuberosas de batata-doce (Ipomoea batatas L. Lam) em condi es in vitro. O experimento com carv o ativado foi conduzido em tubos de ensaio de 150mm x 25mm, contendo 10 ml de meio de cultura por tubo. Nos experimentos com filtro amarelo e fotoperíodo/temperatura foram utilizados frascos contendo 15 e 30ml, respectivamente de meio de cultura por frasco. O meio de cultura utilizado em todos os tratamentos foi o MS. Nos 3 experimentos, avaliou-se o número de estruturas semelhantes a raízes tuberosas, peso seco de raízes e parte aérea. Em rela o ao carv o ativado, notou-se que a sua associa o com ácido naftaleno acético, benzilaminopurina e cinetina prejudicou a forma o de estruturas semelhantes a raízes tuberosas além de proporcionar baixo peso seco de raízes e parte aérea. Em rela o ao filtro amarelo, notou-se que sua presen a com a associa o de reguladores de crescimento (ácido nafatleno acético, benzilaminopurina e cinetina) proporcionou maior forma o de estruturas semelhantes a raízes tuberosas, maior peso seco de raízes e parte aérea. Com rela o à intera o fotoperíodo e temperatura, os tratamentos que mantiveram a temperatura constante de 15masculineC, submetidos a fotoperíodos de 8, 10 e 12h luz, mesmo na presen a de ácido naftaleno acético e cinetina, reduziram a forma o de estruturas semelhantes a raízes tuberosas, peso seco de raízes e parte aérea .

This article discusses the approaches of the theatre of the oppressed in the form of the rainbow of desire, a method of therapy and theatre created by Augusto Boal with psychology, especially with psychodrama. The theatre of the oppressed is often compared and even confused with psychodrama, hence the need to point out some similarities and differences between the two methods, the theories that inspired its creators, as well as the goals that they want to achieve. We will strive to discuss the use of rainbow of desire’s techniques, considering the preparation of the joker to apply them, their management and the authority conferred on it. Boalians’ techniques should be used carefully, and the applicator must not lo
