In spite of the readiness of seeds of Luehea divaricata, your collection is a difficult and onerous task, sees the maturation to be irregular along the time, generating difficulties for production of seedlings through seeds. With base in this, it was aimed to evaluate the most appropriate concentration of IBA in rooting cuttings for the production of seedlings of Luehea divaricata. The cuttings were picked from branches of adult trees and natural regenerations in the spring of 2003, prepared with 10 to 15 centimeters (with a pair of cut leaves to the middle, treated with IBA (0, 2000, 4000, 6000 and 8000 mg L-1) and rooted in greenhouse during 85 days. The medium survival in the exit of the shade house was 29.2%, with superiority for the treatment with 4000 mg L-1 of IBA (42.5%) and, at outdoor conditions, average of 19.8% of survival, with superiority for the treatment of 2000 mg L-1 of IBA (26.5%). None of the studied concentrations was shown technically viable for the production of seedlings of Luehea divaricata with rooting cuttings.Downloads
