Resumo: | Gibberellic acid (GA3) induces flowering of plants of various genera of the Araceae family. Therefore, it was evaluated the effect of GA3 on the growth and yield of Anthurium andraeanum cv. 'Apalai'. For this purpose, micropropagated seedlings were planted in nursery beds under 70% shade. The experimental design was completely randomized in subdivided plots with eight replications. The growth regulation effect was assessed in each plot and the time to flowering after the start of the treatments was assessed in each subplot. The GA3 concentrations were 0, 150, 300, 450 and 600mg L-1, applied every 60 days by spraying on the leaves. The applications and evaluations started after the production of marketable floral stems. Every month the number of leaves was counted and their dimensions were measured, while every week the presence of inflorescences and the point of their commercial harvest were assessed and the respective dimensions were measured. Application of GA3 at 150, 300 and 450 mg L-1 promoted an increase in the leaf area. However, there was no increase in the number of inflorescences produced or their quality, making it impossible to recommend the use of this growth regulator for commercial production of this flower. |

Assim sendo, foi avaliado o efeito do AG3 no crescimento e produção de Anthurium andraeanum cv. 'Apalai'. Para tal, mudas micropropagadas foram plantadas em canteiros sob viveiro com 70% de sombreamento. O delineamento experimental foi inteiramente casualizado em parcelas subdivididas com oito repetições. O efeito do regulador de crescimento foi avaliado na parcela, e o tempo após o início dos tratamentos, avaliado na subparcela. As concentrações de AG3 foram 0, 150, 300, 450 e 600mg L-1, aplicadas a cada 60 dias, por meio de pulverização foliar. As aplicações e avaliações foram iniciadas após a produção de hastes florais comercializáveis. Mensalmente, foi avaliado o número de folhas e determinadas suas dimensões. Semanalmente, foi avaliada a presença da inflorescência e, no ponto de colheita comercial, suas dimensões. AG3 a 150, 300 and 450mg L-1 promoveu aumento na área foliar da planta. No entanto, não houve aumento do número de inflorescências produzidas ou qualidade, o que torna inviável a recomendação deste regulador de crescimento para uso em área de produção comercial.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista Júlio de Mesquita Filho Câmpus Experimental de RegistroAgência Paulista de Tecnologia dos AgronegóciosUniversidade Estadual Paulista Júlio de Mesquita Filho Câmpus Experimental de RegistroUniversidade Federal de Santa MariaUniversidade Estadual Paulista (Unesp)Agência Paulista de Tecnologia dos Agronegócios (APTA)Lima, Juliana DominguesAnsante, Nathalia FelipeNomura, Edson ShigueakiFuzitani, Eduardo JunSilva, Silvia Helena Modenese-gorla Da2015-02-02T12:39:43Z2015-02-02T12:39:43Z2014info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article1327-1333application/pdfhttp://dx.doi.org/10.1590/0103-8478cr20120586Ciência Rural.
