This study analyses the influence of auxin and wounding on the rooting of stem cuttings of Protea ‘Susara’ (P. magnifica × P. susannae) prepared from proleptic shoots. Two assays were carried out. Terminal cuttings, 10-15 cm long, treated with 4000 mg L–1 of indole-3-butyric acid (IBA) and wounded or not were used in the first experiment. The combination of wounding + IBA did not significantly improved rooting compared with the use of IBA alone (70% and 53.3% of transplantable cuttings, respectively). Three levels of IBA (0, 2,000 and 4,000 mg L–1 ) , with or without wounding, and cuttings including the total length of the shoot were used in the second assay. At the end of the trial (24 weeks), wounded cuttings treated with 2,000 mg L–1 or 4,000 mg L–1 of IBA yielded 90% of transplantable cuttings. The combination of wounding + IBA significantly favoured rooting in comparison with the use of IBA or wounding alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
