Resumo: | The natural flowering of the pineapple plant is constituted in one of the most serious problems of its management, due to desuniformization and harvest in unsuitable times, lifting up the cost of production and reduction of the sale price. The objective of this study was to evaluate the behavior of diquat and urea as growth regulators in delaying floral induction of pineapple cv. Pearl. It was tested concentrations of 0; 15 mg L-1; 23 mg L-1; 30 mg L-1 of diquat, with and without urea (20 g L-1), using 50 mL-1 syrup over the leaves of pineapple only once. The experimental design was randomized blocks with four repetitions. It was evaluated the inhibition of natural flowering in three dates, the mass of fruits, the mass of the crown, the mass of the offspring and the number of offspring per plant, the length and width of leaves "D" and soluble solids (ºBrix). The results showed that the application of 30 ml L-1 diquat have delayed the natural flowering, but caused reduction in the fruit mass. The treatment of 23 ml L-1 with urea also established a reduction in flowering natural, without; however, cause reduction in the fruit size. The doses of diquat did not interfere in the mass and production of offspring, length of leaf "D" and the content of soluble solids (ºBrix) of the fruit juice. The urea potentiated the action of diquat in delaying the natural flowering. |

The objective of this study was to evaluate the behavior of diquat and urea as growth regulators in delaying floral induction of pineapple cv. Pearl. It was tested concentrations of 0; 15 mg L-1; 23 mg L-1; 30 mg L-1 of diquat, with and without urea (20 g L-1), using 50 mL-1 syrup over the leaves of pineapple only once.

O objetivo deste trabalho foi avaliar o comportamento do diquat e da ureia como fitorreguladores no retardamento da diferenciação floral do abacaxizeiro cv. Pérola. Foram testadas as concentrações de 0; 15 mg L-1; 23 mg L-1; e 30 mg L-1 de diquat, sem e com ureia (20 g L-1), aplicando 50 mL-1 de calda sobre as folhas do abacaxizeiro uma única vez. O delineamento utilizado foi o de blocos casualizados, com quatro repetições. Avaliaram-se a inibição da floração natural em três datas, a massa dos frutos, a massa da coroa, a massa dos filhotes e o número de filhotes por planta, o comprimento e a largura da folha "D" e os sólidos solúveis (ºBrix). Os resultados mostraram que a aplicação de 30 ml L-1 de diquat retardou a floração natural, mas causou redução na massa dos frutos. O tratamento de 23 ml L-1 com ureia também determinou uma redução na floração natural, sem, no entanto, causar diminuição dos frutos. As doses de diquat não interferiram na massa e na produção de filhotes, no comprimento da folha "D" e no teor de sólidos solúveis (º Brix) do suco dos frutos. A ureia potencializou a ação do diquat no retardamento da floração.Sociedade Brasileira de Fruticultura2020-01-08T16:37:25Z2020-01-08T16:37:25Z2011-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfKIST, H.
