Resumo: Obtaining the rootstock is one of the time consuming steps in the production chain of citrus seedlings, due to the time required for seed germination and early seedling development. In this context, the objective was to evaluate the effects of the use of plant growth regulator on initial seedling rootstock citrus mandarin "Cleopatra". The treatments were related to the concentrations of the commercial product Stimulate ®: control (without plant growth regulator), 6, 12, 18, 24 and 30 mL.kg-1 seed. The seeds were sown in trays of 72 cells. After 70 days of germination, the following characteristics were evaluated: length (cm) and diameter (mm) of the stem, number of leaves, leaf area (dm2 ), dry weight of leaf, stem and root (g), root length (cm) and concentration of chlorophyll "a", "b" and total (mg.m-2 ). The application of Stimulate ® growth at a dose of 6 mL.kg-1 promoted the growth of seedlings of citrus rootstock 'Cleopatra' mandarin, and its use is promising, leading to a reduction in production time rootstock focus on achieving grafting.

Neste contexto objetivou-se avaliar os efeitos do uso de bioestimulante no desenvolvimento inicial de plântulas do porta-enxerto cítrico tangerineira “Cleopatra”. Os tratamentos utilizados foram correspondentes às concentrações do produto comercial Stimulate ®: testemunha (sem bioestimulante), 6, 12, 18, 24 e 30 mL.kg-1 de sementes. As sementes foram semeadas em bandejas de 72 células. Após 70 dias da germinação, foram avaliadas a seguintes características: comprimento (cm) e diâmetro (mm) do caule, número de folhas, área foliar (dm2 ), massa seca de folha, caule e raiz (g), comprimento da raiz (cm) e teores de clorofila “a”, “b” e total (mg.m-2 ). A aplicação do bioestimulante Stimulate®, na dose de 6 mL.kg-1 promoveu o crescimento das plântulas do porta-enxerto cítrico tangerineira “Cleópatra”, sendo seu uso promissor, promovendo a diminuição no tempo de produção do porta-enxerto visando a realização da enxertia.Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Horticultura, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Horticultura, Botucatu, SP, BrasilUniversidade Estadual Paulista (Unesp)Souza, Jackyson Mirellys Azevedo [UNESP]Gonçalves, Bruno Henrique Leite [UNESP]Santos, Adelana Maria Freitas [UNESP]Ferraz, Rafael Augusto [UNESP]Leonel, Sarita [UNESP]2016-07-07T12:36:11Z2016-07-07T12:36:11Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article1-8application/pdfhttps://www.scientiaplena.org.br/sp/article/view/1462Scientia Plena, v. 9, n. 8, p. 1-8, 2013.1808-2793http://hdl.handle.net/11449/140962ISSN1808-2793-2013-09-08-01-08.pdf7493261433527075Currículo Lattesreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPporScientia Plenainfo:eu-repo/semantics/openAccess2024-04-30T14:33:26Zoai:repositorio.unesp.br:11449/140962Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T16:13:31.536153Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
