Aspectos físicos e fisiológicos de sementes de Fimbristylis dicothoma relacionados à germinação e dormência

In the seeds of pioneer plants, the application of treatments for breaking dormancy, and selection by colour and size, are strategies for obtaining seeds of less dormancy and better germination performance. The aim of this study was to evaluate the effect of the physical and physiological aspects of seeds of the tall fringe-rush (Fimbristylis dichotoma) on germination and dormancy. To do this, the seeds were submitted to the following treatments in three studies: (i) control, immersion in H2SO4 (98%, 36N) for 1 minute, immersion in KNO3 (1, 2 and 3%) for 15 minutes, seeding on a substrate moistened with KNO3 (0.2%) and exposure for 5 and 10 hours in a forced air circulation oven at 40 and 70 degrees C; (ii) classification of the seeds by colour (light and dark) and application of the following treatments: control, immersion of the seeds in H2SO4 (98%, 36N) for 1 and 2 minutes, immersion in KNO3 (5% and 10%) for 15 and 30 minutes and seeding on a substrate moistened with KNO3 (0.2%); (iii) classification by size (0.60, 0.50 and 0.40 mm) and germination on a substrate moistened with KNO3 (0.2%) or distilled H2O. The seeds were evaluated by germination test, first count and germination speed index. Moistening the substrate with KNO3 (0.2%), and heat treatment at 40 degrees C for 10 hours improve performance in seeds of the tall fringe-rush. Light-coloured seeds do not display dormancy. Medium-sized seeds of the tall fringe-rush show better performance in terms of percentage and speed of germination.

Data analysis collected from Interviews, questionnaires, narratives and drawings, showed results in favor of the tales reading practice. Conclusion. The humanization strategy of care supported by fairy tales reading, had a positive impact in the children’s admission to the hospital.

A enxertia na cultura do maracujazeiro: aspectos anatômicos, bioquímicos e fisiológicos

Due to the expansion of orchards, problems with soil pathogens are frequent and cause injury and/or make passion fruit cultivation impossible in Brazil. Thus, studies with potential species for rootstocks become indispensable to assist in the technological development of the culture. It is necessary to take into account several aspects of grafting, for the adoption of appropriate techniques, among them we can highlight the anatomy, physiology and also biochemistry. This study aimed to review the existing papers related to grafting of passion fruit and also to understand the operation of grafting itself. It was observed that several publications are related to the topic of the present review and that grafting is a viable alternative to the cultivation of passion fruit, however additional studies about grafting and production are needed.

Alfabetização e letramento: as nuances desses fenômenos por meio dos gêneros do discurso

Literature sample that the basic literacy with literacy differentiates the development of the citizens forming them to act in critical way in society. This research had as objective to analyze nuances of the basic literacy process and literacy of a pupil who little if express verbally, in the classroom, having the discursivos sorts as entered. Case study is about a research of qualitative interpretativa boarding of the type. The data had been collected by the following instruments: systematic comment, interviews with three professors of the citizen, daily of field and written production of the citizen. The results of the research point, on the other hand, with respect to the education of the writing and initial reading that if restricts to the basic literacy concept as technique of the writing, codification and decoding, without advancing for the basic literacy as apprehension and understanding of meanings. On the other hand, they point that the initial writing is organized to reach only the independent literacy, while the ideological literacy is distant of the pertaining to school universe, in the initial years of Basic Education
