Resumo: We aimed to evaluate the effect of seasonality and nutrient solutions in production, survival, rooting and roots vigor of juvenile Araucaria angustifolia minicuttings, as well as the growth habit of formed seedling. Ministumps were managed in semi-hydroponic system where we applied two nutrient solutions with different nutrients concentrations supplied by dripping during the four seasons. After 11 collections, the ministumps showed 100% survival and the highest production occurred in summer with 1,356 minicuttings.m-2.year-1, and the lowest in winter, with 429 minicuttings.m-2.year-1. The winter collections showed the best rooting results, with an average of 83% in the shade house, versus 31% of other seasons. The greatest roots vigor was obtained in spring and summer collections, and the lowest in winter. The most concentrated nutrient solution resulted in higher minicuttings production and better roots vigor and all the obtained minicuttings showed orthotropic growth habit. The minicuttings technique with vegetative propagules of seminal origin proved to be potential for minicuttings production of A. angustifolia, being significantly influenced by season and nutrient solution employed.

As minicepas foram manejadas em minijardim sob sistema semi-hidropônico, em que foram aplicadas duas soluções nutritivas, com diferentes concentrações de nutrientes, fornecidas por gotejamento, durante as quatro estações do ano. Após 11 coletas, as minicepas apresentaram 100% de sobrevivência. A maior produção ocorreu no verão, com 1.356 miniestacas.m-2.ano-1, e a menor no inverno, com 429 miniestacas.m-2.ano-1. As coletas de inverno apresentaram os melhores resultados de enraizamento, com média de 83% em casa de sombra, contra 31% das demais estações. O maior vigor radicial ocorreu nas coletas de primavera e verão e o menor, no inverno. A solução nutritiva mais concentrada propiciou maior produção de miniestacas e melhor vigor radicial, e todas as mudas resultantes da miniestaquia apresentaram hábito ortotrópico de crescimento. A técnica de miniestaquia com propágulos vegetativos de origem seminal mostrou-se potencial para a produção de mudas de araucária, sendo significativamente influenciada pela época do ano e pelas soluções nutritivas empregadas.Sociedade de Investigações Florestais2019-10-25T12:37:20Z2019-10-25T12:37:20Z2015info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPIRES, P. et al.
