Due to low rates of rooting it is difficult to propagate selected clones of Acacia mearnsii by cuttings. The purpose of this study was to define a protocol for disinfection of nodal segments for in vitro introduction, aiming to improve the species genetically for forest plantation. Combination of different products concentration (70% ethyl alcohol, sodium hypochlorite, plant preservative mixture and mercuric chloride), immersion period and size of nodal segment were tested. The best disinfection treatment was the combination of 70% ethanol, 0.4% mercuric chloride, sodium hypochlorite at 2% in nodal segments of 10 mm, with 80% survival. |
