Resumo: | Due to low rates of rooting it is difficult to propagate selected clones of Acacia mearnsii by cuttings. The purpose of this study was to define a protocol for disinfection of nodal segments for in vitro introduction, aiming to improve the species genetically for forest plantation. Combination of different products concentration (70% ethyl alcohol, sodium hypochlorite, plant preservative mixture and mercuric chloride), immersion period and size of nodal segment were tested. The best disinfection treatment was the combination of 70% ethanol, 0.4% mercuric chloride, sodium hypochlorite at 2% in nodal segments of 10 mm, with 80% survival. |

O objetivo deste estudo foi o desenvolvimento de um protocolo de desinfestação para introdução in vitro de segmentos nodais de clones selecionados de A. mearnsii, visando aprimorar o melhoramento genético da espécie para plantios florestais. A desinfestação de propágulos, provenientes de jardim clonal, foi realizada combinando diferentes produtos e concentrações (álcool etílico 70%, hipoclorito de sódio, plant preservative mixture e cloreto de mercúrio), tempo de imersão e tamanho dos segmentos nodais (4 mm e 10 mm). Segmentos nodais de 10 mm responderam melhor ao tratamento de desinfestação, com 80% de sobrevivência, combinando álcool etílico 70%, cloreto de mercúrio a 0,4% e hipoclorito de sódio a 2%.Embrapa Florestas2017-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/139210.4336/2017.pfb.37.92.1392Pesquisa Florestal Brasileira; v. 37 n. 92 (2017): out./dez.; 485-491Pesquisa Florestal Brasileira; Vol. 37 No. 92 (2017): out./dez.; 485-4911983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1392/607https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1392/1378https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1392/1379Salles, Ecléia Alexandra Poltronieri BudaAlcantara, Giovana BomfimQuoirin, Marguerite Germaine GhislaineGonçalves, Antonio NatalHiga, Antonio Rioyeiinfo:eu-repo/semantics/openAccess2019-01-02T18:39:23Zoai:pfb.cnpf.embrapa.br/pfb:article/1392Revistahttps://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:2019-01-02T18:39:23Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
