The objective of this work was to evaluate the grafting of Araucaria angustifolia in two container volumes and at three heights. Rootstocks with 30±5.0 cm were grafted with 4.0±1.0-cm buds in 110 and 280-cm3 plastic tubes (containers) at three heights (5.0±1.0, 10±1.0, and 15±1.0 cm). There was a reduction in graft survival as the height of the grafting point increased, and the lower volume limited the development of the root system. Therefore, grafting at 5.0±1.0 cm in 280-cm3 containers brings new perspectives to improve the clonal forestry of the species, with a significant reduction in plants production time (of up to 12 months), as well as in production costs, used materials, and physical area.
Investigou-se a satisfação dos adolescentes com a imagem corporal, o entendimento sobre transtornos alimentares e se o tema é discutido nas disciplinas de Ciências e Biologia. O estudo foi realizado com 92 adolescentes no município de Ponta Grossa - PR, Brasil. Utilizou-se o questionário Eating Behaviour and Body image Test, juntamente com 4 questões abertas. Para as questões contidas no questionário foi analisada a frequência relativa e para a análise das questões abertas empregou-se a Análise de Conteúdo. Observou-se que a maioria dos adolescentes apresentou insatisfação com o corpo e/ou peso. O entendimento acerca de transtornos alimentares foi fragmentado e o tema era pouco trabalhado. Esses resultados reforçam a importância de abordar a temática no ensino de Ciências e Biologia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
