The aim of this work was to study the effect of different diameters of cuttings on the propagation and growth of Lippia alba. Cuttings of 25 cm length, with three different diameters: 0.3-0.5 cm, 0.6-0.9 cm and 1-1.2 cm, were tested. At 30 and 60 days after the planting of cuttings, the following biometric parameters were determined rooting percentage; number of buds, length of buds; dry matter of buds, cuttings and roots; and total dry matter. All diameters of cuttings presented high rates of rooting after 30 days, confirming that L. alba is an easy-to-root species. L. alba seedling production should use cuttings between 1-1.2 cm diameter, which was better than the others diameters considering most of the tested parameters.
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.
