Influência de bioestimulante no desenvolvimento de plantas de pepino japonês enxertadas e não enxertados em condições de ambiente protegido

The aim of this experiment was evaluate the effect of the bioestimulant administered in grafted and non-grafted japanese cucumber (Cucumis sativus L.) plants, under greenhouse conditions, in gas exchanges during the development of the plant and in the increase of yield. The experiment was carried out in the experimental area of Agronomic Sciences University of UNESP, Campus of Botucatu, São Paulo State, Brazil. The experiment design was completely randomized, in a factorial arrangement of 2x5, grafted and non-grafted plants and 5 treatments with bioestimulant: control, indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 250 mL ha-1; indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 375 mL ha-1; indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 500 mL ha-1; Yuca extract (Yucca elephantipes) + manganese + iron + copper + sulfur 375 mL ha-1 applied 15 days after the transplant, in intervals of 7 days between the applications, via leaf. The effect of the treatments were evaluated through the observations of the following characteristics: production of fruits (number and mass), average mass of the fruit and measures of gas exchanges. It can be concluded that indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 250 mL ha-1 increased CO2 assimilation rate and the water efficiency, influencing in addition to increase the quantity of the fruits

Influência do uso de malhas de sombreamento azul, vermelha e preta no desenvolvimento inicial do pepino Taiko

Cucumber (Cucumis sativus L.) is a plant of the Cucurbitaceae family of great commercial importance and their culture is widespread throughout the country. The production of vegetables, high-quality care begins with training ranging from seedlings and shading techniques have an important role in creating environments more conducive to the production of seedlings and many researchers and producers of seedlings have opted for the use of color shading screens, making this way, the wavelength and the amount of incident energy are changed in favor of the plants. Work will be performed at the Department of Forest Sciences, Faculty of Agricultural Sciences, Universidade Estadual Paulista (UNESP), Botucatu campus. The statistical design will be in three blocks, each containing 100 plots of each treatment (seedlings covered with blue screen, red and black). Evaluations of dry mass and height will be made at 7, 14, 21 and 28 days after emergence, and 5 will be selected seedlings of each treatment. At 14 and 28 DAE was measured, and SPAD chlorophyll content at 30 DAE, was evaluated by measuring gas exchange in the second pair of leaves, fully expanded for each plant, which was put in a chamber controlled with infrared gas analyzer (IRGA LI 6400, Licor) to perform measurements of photosynthesis. Treatment with black shading showed statistically better results for total dry matter, plant height, SPAD chlorophyll content and net assimilation of CO2, showing a better quality seedlings and its use is recommended in the cultivation of cucumber Taiko

Mais ou menos negra? Questões de negritude, tradução e a poesia de Harryette Mullen

This paper addresses issues regarding my translation of selected poems by Harryette Mullen, a rising African-American contemporary poet, whose dense poetry works on the black oral tradition, the experimentalism of writing, the (African-American) pop music, in addition to delving into issues such as the representation of (black) female sexuality. One of the complex aspects of her poetry is the notion of miscegenation, conceived as an aesthetic argument and as a constitutive condition of the identity of multiracial Americans. This concept establishes a textuality that questions the accessible intelligibility generally expected from black American poetry, insofar as a mosaic of dissonant voices are brought to light in her text, which makes it difficult to categorize. In Brazil, especially among politically engaged Afro-Brazilians, there has been criticism towards the praise of miscegenation, since the latter has been considered to support of the myth of racial democracy. Building on these aspects, we investigate the extent to which it is a challenge to translate her poetry – based on miscegenation and hybridity as aesthetic constructs – especially when taking into account the discursive locus of readers identified with an Afro-Brazilian aesthetic, particularly critical of miscegenation. From the point of view of translation, we evaluate the extent to which her poetry could be read by the predominant cultural discourse in Brazil, inclined to favor miscegenation as an integral concept of national identity, as a seductively experimental poetry. In view of this, one wonders whether this perspective makes hers poetry “less black” for Afro-Brazilian literary standards.

Casos de ensino relacionados à educação física escolar: uma produção dos alunos do ensino médio

Teaching cases are records, through written narratives, of an academic episode or incident, they appear in educational scenery as a rich strategy not only for the teacher's conformation but also for their investigation. The bibliography shows that young students are still not very much investigated and it contributes to the establishment of negative images of this social subject. In this sense, the objective of this work is to analyze the stories and episodes, called teaching cases, in narrative style, written by students from High School about their physical education classes. The participants of this study are High School students from two public schools from two cities in the countryside of São Paulo state. The researcher stayed in the schools for nine months and in this meantime she made contact with the students, asking, for the ones who showed interest, the construction of teaching cases. For this interested students, the researcher explained researcher explained what teaching cases are, as well as, she presented a template to guide them in the production. At the end of this process, twenty teaching cases were delivered to the researcher. They were analyzed under the qualitative approach, valuing the expressive wealth in the narratives, complemented by the interviews with the authors. Inset the mosaic of narratives and interviews, showing a variety of experiences and possibilities of distance and approximation of the students to the physical education classes, we can indicate that from the 20 cases, only one was set as a total distance from the physical education classes (this is the student's situation since she was in the second grade from elementary school). Mentioning the positive experiences and the approximation to the physical education classes, the association of teaching cases and interviews showed that seven students lived the context and until today present an affective proximity to the classes. These evidences can help...

Avaliação do potencial citotóxico, moluscicida e alelopático dos extratos hidroetanólicos das folhas de Stryphnodendron obovatum Benth

Stryphnodendron obovatum Benth. known as barbatimão de folha miúda, is a typical tree of the Midwest and Southeast “Cerrado” regions of Brazil. Several secondary metabolites have been identified in its barks, including tannins, described on the literature as allelochemicals. Beholding to identify a possible allelopathic activity in S. obovatum leaves, we tested hydroethanolic EtOH:H2 O (70% and 50% v/v) extracts, in different concentrations, on the initial development of cucumber (Cucumis sativus L.). Among the results, we highlight the effect of the 50% hydroethanolic extract in inhibiting the formation of the main and the secondary roots and the stimulation of the hypocotyl growth in C. sativus by the 70% hydroethanolic extract, both in all concentrations tested. The cytotoxic activity, evaluated by bioassay toxicity on Artemia salina Leach., was negative for the tested extracts (LC50> 1000 mg.mL-1). Concomitantly, the molluscicidal activity, evaluated against snails of Biomphalaria glabrata Say, presented low acute toxicity of solutions of 70% hydroethanolic extract at concentrations of 128.9 mg.mL-1 and 172.8 mg.mL-1 and values above 250 mg.mL-1 to solutions of 50% hydroalcoholic extract, being therefore considered inactive for these. The results suggest the existence of allelochemicals in the extracts tested and they have low toxicity.
