- W2912952390 abstract "O interesse na fruta pitaia tem crescido nos últimos 20 anos e estudos sobre a propagação e uso de fitorreguladores nesta cultura são incipientes. Este trabalho teve como objetivo estudar o efeito da aplicação de 6-Benziloaminopurina (BAP) na estaquia da pitaia. O experimento foi conduzido na Casa de Vegetação de Propagação do Departamento de Fitotecnia da Universidade Federal Rural do Rio de Janeiro. Em delineamento fatorial inteiramente casualizado (DIC) com 2 formas de inoculação (imersão e Aplicação em corte no ápice da estaca) e 4 doses de BAP (0,50,100 e 150 mg L-1). Foram avaliados os dados de Sobrevivência (S), o Número de brotações Emitidas (NB), a Soma do Comprimento das Brotações (CB), a Massa Fresca (MFB) e Seca das Brotações (MSB) aos 100 dias após o plantio das estacas (DAP) e o efeito na Rebrota aos 200 dias (DAP). Houve sobrevivência de 100%. Verificou-se um padrão linear crescente no incremento de NB por dose de BAP, e um padrão quadrático para as avaliações de CB, MFB e MSB com ponto máximo de 80 mg L-1 de BAP. Nenhum efeito significativo foi observado nos dados da Rebrota.Palavras-chave: Hylocereus undatus, propagação, citocinina. EFFECTS OF CYTOKININ BENZYLAMINOPURINE IN PITAYA CUTTINGS ABSTRACT: The interest in the pitaya has grown in the last 20 years and studies on the dragon fruit propagation and use of phytorregulators are incipient. This work aimed to study the effect of application of 6-Benzyloaminopurine (BAP) on pitaya cuttings. The experiment was conducted at the Propagation Vegetation House of the Crop Science Department of the Federal Rural of Rio de Janeiro University. In completely randomized factorial design (DIC) with 2 forms of inoculation (immersion and Application in cut at the apex of the stakes) and 4 doses of BAP (0, 50, 100 and 150 mg L-1). The data of Survival (S), Number of sprouted shoots (NB), Sprouting length (CB), Fresh mass (MFB) and Sprout drying (MSB) were evaluated at 100 days after planting the cuttings (DAP) and the effect on regrowth (Rebrota) at 200 days (DAP). There was 100% survival. There was a linear pattern in the increase of NB per dose of BAP, and a quadratic pattern for the evaluations of CB, MFB and MSB with maximum point of 80mg L-1 of BAP. No significant effect was observed in the data from regrowth.Keywords: Hylocereus undatus, propagation, cytokinin." @default.
