要約:In order to assess the effect of the dose of indole-3-butyric acid on rooting of cuttings of Mulberry (Morus spp.), is a deciduous tree, which is used for the feeding of the silkworm and domestic species feed. This species has shown good potential as forage shrub in tropical countries. Currently, Ecuador is investigating its use and this is why it is important to study their spread, the different hormone levels in inducing roots on cuttings of Mulberry (Morus spp.), including indole-butyric acid (IBA), at a dose of 2000 mg kg-1 of IBA, 4000 mg kg-1 of IBA, 6000 mg kg-1 of IBA, 8000 mg kg-1 of AIB and a control (without hormone)combined with the substratum Earth and sand that make up treatments in study. A design fully applied at random with five treatments and five replications and ten observations per experimental unit. 45 Days assessed the percentage of rooting percentage, mortality, greater root and root mass, length, number of roots by applying the Tukey test to determine significant differences between measures of treatments. In general the best response was obtained in the T2 concentration of indolebutyric acid (IBA) of 4000 mg Kg - 1 AIB was the best number of roots 15.80; 15.26 root length cm; root mass 5.50 gr; the percentage of rooting of 85.6% and mortality of 1440% surpassing the witness and other treatments, and also .with 13.75% return; so it can spread vegetatively morera, applying 4000 mg Kg-1 AIB Key words: Rooting of cuttings of Mulberry; Indole-butyric acid
