Modificação da técnica de ramaer para obtenção de plantas gêmeas de seringueira Modification of ramaer's technique to obtain twin plants of rubber tree

O objetivo deste trabalho foi aumentar a porcentagem de sucesso na obtenção de plantas gêmeas de seringueira de tamanhos iguais pela modificação da técnica de Ramaer, que utiliza sementes em fase final de germinação, quando a radícula atinge mais de 3 cm de comprimento, dificultando o seccionamento longitudinal em duas metades, a partir da inserção das alças cotiledonares. Foi testado o corte longitudinal em duas etapas, primeiro da ponta emergente da radícula, com 3 mm de comprimento, até 1 cm acima do coleto. Após a regeneração de duas radículas iguais, foi concluído o seccionamento conforme a técnica de Ramaer. A porcentagem de plantas gêmeas de tamanhos iguais foi de 82,5 com o método modificado e de 52,5 com a técnica de Ramaer.<br>The objective of this work was to enhance the success of obtaining twin rubber plants of equal size, by turning easy the Ramaer's technique, which consist of using seeds in the final stage of germination when radicle shows more than 3 cm length and the longitudinal splitting in two halves of equal size up to the cotyledonary arms. A longitudinal sectioning in two stages was tested, first of emerging tip of the radicle, 3.0 mm long, up to 1.0 cm above the root collar. After the regeneration of two equal radicles, the sectioning was concluded according to the Ramaer technique. The percentage of equal sized twin plants was 82.5 with the modified method and 52.5 with the Ramaer technique
