Induction of rooting in cuttings of Malvaviscus arboreus Cav. with different concentrations of Indolbutiric Acid (IBA) - DOI: 10.4025/actasciagron.v31i2.799

Abstract

The study evaluated the effect of three concentrations of auxin (0; 2,000 and 6,000 ppm) (indolbutiric acid - IBA) in inducing the formation of adventitious roots in three types of stem stakes (herbaceous, woody and semi-woody) of wax mallow (Malvaviscus arboreus Cav.). The stakes were cut into a bezel angle, with approximately 12 cm each, treated with the fungicide Benlate and later with IBA. The assessments were made 30 days after planting, evaluating the appearance or absence of calluses, roots and shoots. Among the stakes, the woody ones showed the best regenerative capacity, reaching the maximum corpus callosum, rooting and shooting, regardless of IBA concentration. In the treatment with 2000 ppm IBA concentration, herbaceous and woody stakes showed the best results for rooting.
