CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Considerando o grande potencial de exploraÃÃo agroindustrial da cajazeira (Spondias mombin L.) e as dificuldades para a produÃÃo de mudas por estaquia realizou-se este trabalho com o objetivo de avaliar a propagaÃÃo vegetativa de cajazeira por estaquia de caule do clone Lagoa Redonda, com o uso de Ãcido indolbutÃrico e de diferentes tipos de estaca. As estacas foram retiradas de plantas adultas, sadias com nove anos de idade do clone copa de cajazeira Lagoa Redonda enxertado sobre umbuzeiro. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 3x2, sendo os fatores: tipos de estaca (apical, mediana e basal) e doses de AIB (0 e 1.000 mg.L-1), com cinco repetiÃÃes e oito estacas por parcela, totalizando 240 estacas. ApÃs a aplicaÃÃo dos tratamentos, as estacas foram colocadas para enraizar em sacos plÃsticos de polietileno contendo como substrato uma mistura de solo hidromÃrfico, esterco bovino e areia quartzosa, na proporÃÃo 1:1:1. As avaliaÃÃes foram realizadas 165 dias apÃs o plantio, sendo avaliado o nÃmero de estacas mortas (EM), de estacas dormentes (ED), de estacas com brotaÃÃes ativas (EBA), de estacas com brotaÃÃes dormentes (EBD), de estacas com calo (EC), de estacas enraizadas (EE), o nÃmero de brotaÃÃes ativas (NBA), de brotaÃÃes dormentes (NBD), de folhas (NF) e de folÃolos (Nfo), a massa seca foliar (MSF) e radicular (MSR), e tambÃm, o nÃmero de mudas aptas para plantio. Observou-se que, apenas para o fator tipo de estaca, houve efeito significativo para as seguintes variÃveis: ED, EBD, NF, Nfo, MSF e MSR. A aplicaÃÃo de AIB ou a sua interaÃÃo com os tipos de estacas nÃo tiveram efeito sobre as variÃveis. A sobrevivÃncia dos trÃs tipos de estacas pode ser considerada elevada. Nas estacas apicais percebeu-se que o efeito da dominÃncia apical, influenciou algumas variÃveis, como o nÃmero de ED, EBA, o NBA, NF e, consequentemente o Nfo. Observou a formaÃÃo de calo nos trÃs tipos de estacas, no entanto, as estacas basais apresentaram maior tendÃncia à formaÃÃo de raÃzes adventÃcias. A parte aÃrea formada nas estacas basais foi quantitativamente superior ao das estacas apicais e medianas. CorrelaÃÃes significativas foram encontradas para EBA, NBA, Nfo e MSF quando correlacionadas com MSR. As estacas retiradas da porÃÃo basal dos ramos de cajazeira apresentaram melhores condiÃÃes para desenvolvimento de raÃzes. / Considering the great potential of agro-industrial exploration of Spondias mombin L. and the difficulties in the production of seedlings by cutting this work was carried out in order to evaluate the vegetative propagation of stalk cuttings, with the use de IBA and different cuttings of types. Cuttings were taken from adult plants, healthy nine years old clone cup Lagoa Redonda grafted onto the rootstock of Spondias tuberosa. The experimental design was completely randomized in factorial scheme 3x2, with the following factors: types of cuttings (apical, median and basal) and IBA (0 and 1000 mg. L-1), with five replicates of eight cuttings each, total 240 cuttings. After the treatments, the cuttings were placed for rooting in polyethylene plastic bags containing as substrate a mixture of soil hydromorphic, cattle manure and quartz sand in proportion 1:1:1. Evaluations were performed 165 days after planting, being rated the number of dead cuttings, of dormant cuttings, of buds cuttings active, of cuttings with dormant buds, of cuttings with callus, of cuttings rooted, the number of active buds, of dormant buds, of leaves and leaflets, the leaf dry mass and root, and also, those suitable for planting. It was observed that only for the factor type of cuttings, was significant effect for the following variables: dormant cuttings, cuttings with dormant buds, number of leaves, of leaflets and leaf dry mass and root. The application of IBA or its interaction with different types of cuttings had no effect on the variables. Survival of three types of cuttings can be considered high. In apical cuttings it was found that the effect of apical dominance, influence some variables, as the number of dormant cuttings, of active buds cuttings, the number of active buds, of leaves, and consequently the number of leaflets. Callus formation was observed in three types of cuttings, however, the basal cuttings presented more tendencies to form adventitious roots. The shoots formed in the basal cuttings were quantitatively higher than the median and apical cuttings. Significant correlations were found to number of active buds cuttings, number of active buds, number of leaflets and the leaf dry mass when correlated with root dry mass. Cuttings removed from the basal portion of the branches of Spondias mombin L. presented better conditions for root development.
