Resumo: | Gladiolus is an important cut flower commercialized in Brazil, and the use of gibberellic acid (GA3) to cultivate it in a protected environment may promote the production of high quality flower spikes. This study aimed at evaluating the production of flower spikes and corms of gladiolus (‘White Friendship’ cultivar) submitted to high concentrations and application methods of gibberellic acid, in a protected environment. The experimental design was randomized blocks, in a 2 x 4 factorial arrangement, being two application methods (foliar spraying and corm soaking) and four concentrations (0 mg L-1, 250 mg L-1, 500 mg L-1 and 1,000 mg L-1) of gibberellic acid, with six replications and two plants per experimental unit. The following traits were evaluated: plant height, number of leaves per plant, marketable harvest point of flower spikes, number of florets per flower spike, flower panicle length, stem and floret diameter, corm perimeter, number of cormels per plant and production of corm fresh matter and leaf dry matter, flower spikes, corms and cormels. High concentrations of GA3 are not recommended for the production of flower spikes and corms of the gladiolus ‘White Friendship’ cultivar. The corm soaking application method anticipates the harvest of flower spikes and produces a higher number of cormels per plant. Regardless of the application method, the concentration of 550 mg L-1 ofGA3 increases the cormel yield of the ‘White Friendship’ cultivar. |

Objetivou-se avaliar a produção de hastes florais e cormos de gladíolo cv. ‘White Friendship’ submetido a modos de aplicação e altas concentrações de ácido giberélico, em ambiente protegido. O delineamento experimental foi em blocos casualizados, em esquema fatorial 2 x 4, sendo dois modos de aplicação (pulverização foliar e imersão do cormo) x quatro concentrações (0 mg L-1, 250 mg L-1, 500 mg L-1 e 1.000 mg L-1) de ácido giberélico, com seis repetições e duas plantas por unidade experimental. Avaliaram-se a altura da planta, número de folhas por planta, ponto de colheita comercial das hastes florais, número de floretes por haste floral, comprimento do pendão floral, diâmetro do florete e da haste floral, perímetro do cormo, número de cormilhos por planta, produção de matéria fresca do cormo e de matéria seca de folhas, haste floral, cormo e cormilhos. Altas concentrações de GA3 não são recomendadas para a produção de hastes florais e cormos de gladíolo cv. ‘White Friendship’. O modo de aplicação por imersão do cormo antecipa a colheita das hastes florais e produz maior número de cormilhos por planta. Independentemente do modo de aplicação, a concentração de 550 mg L-1 deGA3 incrementa a produção de cormilhos da cultivar ‘White Friendship’.Escola de Agronomia - Universidade Federal de Goiás2017-01-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/42418Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 4, Oct./Dec. 2016; 450-457Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 4, out./dez. 2016; 450-457Pesquisa Agropecuária Tropical; v. 46, n. 4, out./dez. 2016; 450-4571983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/42418/22314Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessCarvalho-Zanão, Maristela PereiraVilla, FabíolaTsutsumi, Claudio YujiPereira, Natália2020-07-13T18:21:44Zoai:ojs.revistas.ufg.br:article/42418Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2020-07-13T18:21:44Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)false |
