Présentation
Mesquite (Prosopis alba Grisebach), an important species in arid and semiarid regions of where is native to South America and North America, Africa and Asia, is currently commercially propagated by seeds, however this method of propagation generates a large genetic variability in commercial plantations, introducing undesirable to commercial production characteristics. The main objective of this work was to evaluate vegetative propagation using the mini-cutting technique and indolebutyric acid (IBA) at different concentrations (0, 3000, 4500, 6000 and 7500 mg L-1) on rooting of P. alba clones. Rooting was achieved in 98-100% of the mini-cuttings at all concentrations tested. Increasing the concentration of IBA the observed an increase in the number of leaves and leaflets of clonal seedlings, as well, fresh matter weight and in number and length of roots to reach its optimum concentration. We propose the mini-cutting technique as a tool for the P. alba cloning.
