Germinação de sementes de maracujazeiros: água, luz, temperatura e reguladores vegetais

The production of seedlings of passion fruit is done mainly with the use of seeds by most producers. It can also be propagated by cuttings, layering and in vitro tissue culture. However, even when grafting is used, it is necessary to use seeds to produce the rootstock. Nevertheless, most Passifloracea species have germination problems, making it difficult to obtain seedlings. Although several studies have been developed in an attempt to increase seed germination of passion fruit there are still difficulties in understanding the germination process and also disagreement about seed dormancy. Thus, the present study aimed to review papers related to seed germination of passion fruit emphasizing aspects such as mechanical resistance to water ingress, the need for adequate light and temperature and the use of plant growth regulators in overcoming seed dormancy. It was noticed that, in general, the passion fruit seeds are photoblastic negative and exhibit physiological dormancy, being no need of seed scarification to stimulate its germination.

Avaliação da cultura do milho submetida à hormesis

Under conservation tillage systems is critical to maintaining plant residues from previous crops on the soil surface. A technique called Hormesis aims to increase the amount of straw and also cause a delay in straw decomposition. Therefore, this study aimed to evaluate the agronomic characteristics of corn under no-tillage system subjected to Hormesis. The experiment was carried out at UNESP campus in the city of Botucatu, SP . The experimental was design in completely randomized blocks. The treatments based on the technique of Hormesis were : control (no application) , sub Gliphosate low dosage (12.5 g.ai.ha - 1 ) , sub Gliphosate average dosage (25 g. ai.ha - 1 ) , sub Gliphosate high dose (50 g. ai.ha -1 ), 2,4-D under low dose (100 g. ai.ha -1 ), 2,4-D sub average dosage (200 g. ai.ha -1 ) 2,4- D under high dosage (300 g. ai.ha -1 ) sub Verdict low dose (0.625 g. ai.ha -1 ) sub Verdict average dosage (1.25 g. ai.ha -1 ) , sub Verdict high dosage (2.5 g. ai.ha - 1 ) . In addition, the following characteristics were evaluated: plant height, first ear growth, stem diameter , ear length , number of rows per cob, cob diameter , , percentage of grains on the cob , mass of plant dry matter, and yield. The results showed that all the treatments showed no statistical difference, the maize was not affected with sub doses of herbicides applications under the field and weather conditions in which the experiment was conducted.

Adubação de sistemas: antecipação de adubação nitrogenada para a cultura do milho em integração lavoura-pecuária

Traditionally in no-tillage systems, fertilization is done to the catch crop. In general nutrient cycling in crop systems has not been treated as an important tool in the process of nutrient supplying for plants. The type and the condition in which vegetable residuesis decomposed can affect the efficiency of nutrient cycling.This study assessed the effect of anticipated nitrogen fertilization in crop-livestock systems on cultivated cornproduction, rate ofnutrient release from plant residue, and theN-minerallevels of soil. The study was carried out in the city Abelardo Luz (SC) in a Clayey Oxisol. The experimental design was a randomized block design with three replications. The treatments were arranged in a 2 x 2 factorial arrangement. The first factor was N Fertilization Time: in the N-Pasture level, nitrogen (200 kg ha-1 N) and N-Grains level, no nitrogen was applied. The second factor was the Grazing Height, characterized by two sward heights of oat at 15 cm (Low Height Pasture) and at 30 cm (High Height Pasture). Corn hybrid ‘Máximus’ was sowed in 10thOctober, 31 days after the removal of animals. In the twelve resulting plots from the combination of treatments on pasture phase (N Fertilization Time x Grazing Height) rates of N-fertilizer (0, 100, 200 e 300 Kg ha-1 of N) as urea were allocated in the split plot.We conclude that anticipated N fertilization of winter cover crop pasture to provide high-quality forage and carry-over N to the subsequent corn crop and may eventually replace side drees nitrogen fertilization on corn and can improve overall N fertilizer efficiency use in integrated crop-livestock systems.The rate of K release from plant residues is very fast, releasing large quantities in the first days after plant desiccation.Despite of considerably high nitrogen dose used in both the pasture and at the grain crop it was not observed nitrate leaching risks during the study period.

Cultural studies and the urgency of interdisciplinarity : sooner, not later, we're going to need a cultural science (Os Estudos Culturais e a urgência por interdisciplinaridade: cedo, e não tarde, vamos precisar de uma Ciência da Cultura)

Most of creativity in the digital world passes unnoticed by the industry practices and policies, and it isn't taken into account in the cultural and economic strategies of the creative industries. We should find ways to catalyze this creative production, showing how the user's contribution may contribute to social learning, cultural and economic advancement. To that effect, we must know what is an open creative system and how it works. Based on this diagnosis, the author that interdisciplinarity is urgent and there is also a need for a science of culture. What is at stake is a strategy of integrated development, as regards the upcoming innovation in its complex, productive and learning aspects.

Propuesta educativa para la promoción de una cultura de donación de órganos

La escasez de órganos para donación y trasplante es un problema acuciante que involucra a toda la sociedad. Existen diversos prejuicios, racionales y emocionales, por los que muchas personas son reacias a donar sus órganos, sin saber o sin comprender que este gesto podría salvar vidas. El autor ahonda en esta problemática médico-social y plantea una propuesta para revertirla, comenzando con la educación desde el nivel primario y abarcando diferentes niveles educativos y ámbitos de la sociedad. Pone especial énfasis en la formación de los jóvenes, y su entorno social y familiar, quienes juegan un papel preponderante en el desarrollo de futuros programas educativos. Esta propuesta es integral y no implica controversias legales ni éticomorales, por lo que se presenta como una alternativa para derribar las barreras, conscientes e inconscientes, y la desinformación generadoras de una sociedad no donante que se niega una posibilidad de vida a sí misma.
