Resumo: Bactris gasipaes produces heart-of-palm. Peach palm is a perennial crop that has a tillering capacity, being an alternative to illegal extraction. There is a lack of studies about vegetative propagation technics for this species. The present study aimed to analyze different tillering induction methods in Bactris gasipaes var. gasipaes seedlings in four different seasons. The treatments were: 1) stem bending; 2) stem bending and application of 150 mg kg-1 of benzylaminopurine; 3) stem bending and application of 150 mg kg-1 of gibberellic acid and; 4) stem girdling. The experimental design was random with 4 replicates of 20 plants per treatment. Anatomical analyses were conducted at the stem, and the tillering and mortality of the treated plants were evaluated. It was possible to identify the stem tissues and the meristematic apex site by anatomical analysis. The stem bending treatments were inefficient; but girdling presented potential as tillers inducer.

Tendo em vista a importância e escassez de estudos sobre a propagação vegetativa dessa espécie e que o aumento do número de perfilhos é pré-requisito chave nessa metodologia, o presente trabalho teve por objetivo estudar diferentes métodos para indução de perfilhos em mudas de pupunheira em quatro épocas diferentes. Os tratamentos constituíram-se de: 1) arqueamento do caule; 2) arqueamento do caule com aplicação de 150 mg kg -1 de benzilaminopurina; 3) arqueamento do caule com aplicação de 150 mg kg-1 de ácido giberélico e; 4) anelamento do caule. O delineamento estatístico foi inteiramente casualizado, com 4 repetições de 20 plantas por tratamento. Estudos anatômicos dos caules foram realizados e a formação de perfilhos e mortalidade das plantas submetidas aos diferentes tratamentos avaliados. As análises anatômicas possibilitaram caracterizar os tecidos do caule e localizar o meristema apical. O arqueamento do caule não foi eficiente, enquanto o anelamento apresenta potencial para a indução de perfilhos.Embrapa Florestas2014-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/54910.4336/2014.pfb.34.77.549Pesquisa Florestal Brasileira; v. 34 n. 77 (2014): jan./mar.; 39-48Pesquisa Florestal Brasileira; Vol. 34 No. 77 (2014): jan./mar.; 39-481983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/549/355Copyright (c) 2014 Ernani Augusto Ochekoski Mossanek, Ivar Wendling, Henrique Soares Koehler, Katia Christina Zuffellato-Ribashttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMossanek, Ernani Augusto OchekoskiWendling, IvarKoehler, Henrique SoaresZuffellato-Ribas, Katia Christina2017-04-28T12:47:45Zoai:pfb.cnpf.embrapa.br/pfb:article/549Revistahttps://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:2017-04-28T12:47:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
