%X Propagation of the fig tree predominately uses hardwood cuttings obtained from pruning stock plants. With a view to optimising fig tree propagation, the effects of auxin and misting on the rooting of herbaceous and hardwood cuttings from the fig tree were evaluated. An experiment was set up in a 2x2x2 factorial design, with two types of cuttings (softwood and hardwood), two levels of auxin (0 and 1000 mg L-1 indolbutyric acid) and two environments (with and without misting). Thirty days after starting the experiment, rooting, root length, sprouting and losses were all evaluated. The interaction of the type of cutting and the auxin was significant for rooting, sprouting, root length and cutting loss. Misting did not affect the variables analysed. In the absence of auxin, there was no difference between the type of cutting for rooting, length of root and sprouting, while the application of auxin (1,000 mg L-1) produced a reduction in these variables. The production of fig tree seedlings can be made from either softwood or hardwood cuttings and does not require the use of auxin or misting. A propaga  o da figueira predomina com o uso de estacas lenhosas obtidas ap¨®s a poda de plantas matrizes. Visando otimizar a propaga  o da figueira, avaliou-se os efeitos da auxina e da nebuliza  o no enraizamento de estacas herb¨¢ceas e lenhosas de figueira. Foi implantado um experimento em fatorial 2x2x2, sendo dois tipos de estacas (herb¨¢ceas e lenhosas), dois n¨ªveis de auxina (0 e 1.000 mg L-1 de ¨¢cido indolbult¨ªrico) e dois ambientes (com ou sem nebuliza  o). Aos 30 dias ap¨®s a implanta  o do experimento, avaliou-se o enraizamento, comprimento da rad¨ªcula, brota  o e perdas. A intera  o do tipo de estaca e auxina foi significativa para enraizamento, brota  o, comprimento da rad¨ªcula e perdas de estacas. A nebuliza  o n o interferiu nas vari¨¢veis analisadas. Na aus¨ºncia de auxina n o houve diferen a entre os tipos de estacas para o enraizamento, comprimento da rad¨ªcula e brota  o, enquanto, a aplica  o de auxina (1.000 mg L-1) proporcionou redu  o para estas vari¨¢veis. A produ  o de mudas de figueira pode ser realizada a partir de estacas herb¨¢ceas ou lenhosas e dispensa o uso de auxina e nebuliza  o.
