Resumo: Piptocarpha angustifolia Dusén ex. Malme (Asteraceae) is a brazilian native and pioneer tree species, occuring in Araucária Forest, with potential to ecosystem restorarion and introduction in forest, agriculture and pasture systems. Its propagation by seed presents irregular production and low number of feasible seeds while vegetative propagation by cutting of mature plants with semihardwood shoots didn’t present rooting response. This work aimed to evalue adventitious rooting by minicutting technique using minisprouts from seeds. The minisprouts were collected and dipped in ascorbic acid solution (1%) and minicuttings were produced with 5 cm lenght mantaining a pair of leaves in the apex installed in a medium with vermiculite and carbonized rice husk (1:1 v v-1). The evaluation was made after 90 days considering percentage of rooting minicuttings, number and lenght average for minicuttings, percentage of living minicuttings, percentage of minicuttings with callus and dead minicuttings. The higher production of minicuttings was verified in winter and spring, varying between 113.4 to 259.2 units for square meter a month. The adventitious rooting reached 45% in winter with 6.3 roots and an average of 9.8 cm of length, without using plant growth regulator.

Malme é uma espécie arbórea nativa brasileira, pioneira, pertencente à Floresta   Ombrófila Mista, com potencialidades para recuperação de   ecossistemas degradados e implantação em sistemas agrossilvipastoris. Sua propagação pela via seminal apresenta  produção irregular e número reduzido de sementes viáveis  além de experimentos de estaquia com ramos semilenhosos não apresentarem resposta para enraizamento adventício. Este trabalho buscou avaliar o potencial de enraizamento da espécie pela técnica da miniestaquia com uso de minicepas originadas por sementes e cultivadas sob sistema semi-hidropônico. As brotações coletadas foram imersas em solução de ácido ascórbico a 1% e as miniestacas confeccionadas com 5 cm de comprimento e manutenção do par de folhas no ápice, instaladas em substrato contendo vermiculita média e casca de arroz carbonizada (1:1 v v-1). Decorridos 90 dias, verificou-se maior produção de miniestacas no inverno e primavera, variando entre 113,4 e 259,2 miniestacas por metro quadrado ao mês. O enraizamento adventício chegou a 45% no inverno com número de raízes igual a 6,3 e comprimento médio de 9,8 cm, sem utilização de fitorregulador.Embrapa Florestas2011-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/17210.4336/2011.pfb.31.67.257Pesquisa Florestal Brasileira; v. 31 n. 67 (2011): jul./set.; 257Pesquisa Florestal Brasileira; Vol. 31 No. 67 (2011): jul./set.; 2571983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/172/224Copyright (c) 2011 Aurea Portes Ferriani, Katia Christina Zuffellato-Ribas, Cristiane Vieira Helm, Adriana Boza, Ivar Wendling, Henrique Soares Koehlerhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessFerriani, Aurea PortesZuffellato-Ribas, Katia ChristinaHelm, Cristiane VieiraBoza, AdrianaWendling, IvarKoehler, Henrique Soares2018-05-29T12:15:02Zoai:pfb.cnpf.embrapa.br/pfb:article/172Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-05-29T12:15:02Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
