Propagation of Theobroma cacao by Rooted Cuttings in Mini-Tunnels

Cacao is an economically important crop that currently planted in Asia, Africa, and America. Cuttings a technique of vegetative propagation suitable for the conservation selected desirable characteristics cacao trees. The objective this study was to evaluate rooting cuttings mini-tunnels with different doses indole-3-butyric acid (IBA) obtain simple viable protocol. experiment carried out under completely randomized design (CRD). 5 7 cm long were collected from middle area tree crowns treated 0, 1000, 2000, 3000 ppm IBA; then they placed Jiffy© pellets set root plastic-covered fog irrigation. results indicate treatments 0 1000 IBA produced highest values survival (100%, both treatments) percentage (87.7 90.0%, respectively) as well number length roots (4.3 roots-4.21 4.5 roots-5.32 length, respectively); likewise, rooted after 24–40 days, followed by (24–46 days). All without (0 ppm) achieved 100% acclimatization nursery. In general, best obtained application (Control all parameters evaluated, similar those these success efficiency protocol proposed study.
