This paper is aiming to evaluate the effects of different levels of the aluminum on the growth of the Eucalyptus grandis x E. urophylla shoots cultivated in vitro. Evaluations were carried out on pH and chemicals modifications of the culture medium by Geochem program, polyamines contents (putrescine, espermidine e espermine) and acid phosphatase ativity on the shoots. The trial had a totally randomized design with four treatments and four replicates. The treatments were: 0.0, 6.75,13.50 and 27 mg.L -1 of AlCl 3.6H 2. Evaluations were carried out on the 4th, 8th, 12th, 16th, 20th, 24th and 28th day of culture. The addition of the aluminium, in all concentrations, affected the culture medium ionic equilibrium, the morphology of the shoots, reduced the pH on the medium, induced an increase in polyamines content and higher acid phosphatase activity.

This article analyzes the short story Folha rota (1878) by Machado de Assis, taking to account the transformation process of the patriarchy, bearing in mind it's decadence within the increasing urbanization context through 19th century. From the representation of female characters and their everyday's life in the narrative, we discuss the violence experienced by free and poor women involved in the inherent power relations in that society. In this perspective, we intend to indicate an interpretation of literary work as an important device of social criticism, as much as, to give a contribution to an accurate comprehension of Machado de Assis's work, especially his short stories.
