RESUMONo presente trabalho foram avaliados o efeito de quatro concentrações de ácido indol butírico AIB (0, 500, 1000 and 1500 mg L -1 ) e dois substratos (areia e vermiculita) na estaquia de Pariparoba-do-Rio Grande do Sul [Piper mikanianum (KUNTH) Steud var. Mikanianum (Piperaceae)]. O experimento baseou-se no delineamento experimental inteiramente casualizado, constando de 15 repetições composta de 30 estacas por tratamento. Verificou-se que o AIB possui efeito no que se refere ao índice de sobrevivência das estacas, independente do substrato utilizado, areia ou vermiculita. Os resultados sugerem que estacas cultivadas no substrato constituído por vermiculita são capazes de formar maior número de folhas, raízes e brotações, cujos valores são proporcionais ao aumento da concentração de AIB, devido a boa retenção de água e ótimo espaço de ar na capacidade de retenção, fatores que lhe possibilitam a manutenção de um adequado suprimento de água para o enraizamento de estacas.Palavras-chave: areia; vermiculita; enraizamento; Piper mikanianum. ABSTRACTThis work was made to study the effect two different substrate (sand and vermiculite) and four concentration (0, 500, 1000 and 1500 mg L -1 ) indol butyric acid IBA on the cutting of "Pariparoba-do-Rio Grande do Sul" [Piper mikanianum (KUNTH) Steud var. Mikanianum (Piperaceae)]. The experiments were basal, randomly distributed in 15 repetitions of 30 cutting for treatment. It was detected for AIB was affected survival rate independ to used substrate, sand or vermiculite. The results suggest that cutting cultivated in sand substrate are capable to form bigger number of roots with lesser concentration of AIB due to bigger aeration, in detriment of those composed by in corporate substrate for vermiculite. Because there was water retention and excellent air space in the maintenances of adequate water supplement for the rooting of cuttings.
