Abstract:
Caesalpinia ferrea Mart. ex Tul. var. ferrea is a tree of northeastern Brazil and has use medicinal, timber, ornamental and forage. The seeds have dormancy which hinders the production of seedlings. The aim of this work was to evaluate the rooting of cuttings from aereal part and rhizome of C. ferrea in 12 experiments at different times to collect cuttings, cuttings types, substrates and use of indole butyric acid (IBA). The percentage of rooting of cuttings from aereal part was less than 30% even with the use of IBA. At 50 days after planting was found 85% of rooting of cuttings from rhizome treated with 6000 mg L-1 IBA. The lowest average rooting (40%), number of roots (1.8) and root length (3.2 cm) occurred in cuttings without IBA, highlighting the importance of using rooting hormone. Propagation by cutting from aereal part of C. ferrea is not feasible. C. ferrea can be propagated by cuttings extracted from rooting system of plants with 16 months of age, with 18cm long and treated with 6000 mg L-1 of IBA.
