Abstract

Erythrina crista-galli L. is a tree species native to wetlands and pioneer
formations in Brazil, displaying significant ornamental and landscape potential due to its
vibrant clusters of red and pink flowers, which attract hummingbirds, bees, and other
pollinators. Additionally, the species exhibits medicinal properties and contributes to the
recovery of degraded environments and soils contaminated by petroleum. However,
seedlings of this species are not found in large-scale production or sale in nurseries and
flower shops in Curitiba and surrounding areas. Studies indicate that only 6% of Erythrina
crista-galli L. flowers produce seeds, and there is limited information on the viability and
germination of these seeds, posing challenges to cultivation. Therefore, this study aimed
to analyze the vegetative propagation of the species using different types of stem cuttings:
non-rejuvenated (from year-old shoots), mini-cuttings (produced from epicormic shoots of
non-rejuvenated material), and rejuvenated material cuttings (from matrix regrowth), with
the application of indole butyric acid (IBA) at different concentrations at the base of the
cuttings. The highest rooting percentage and lowest mortality rate were observed in the
mini-cutting experiment without IBA application. The rooting rate was 62.86%, and the
mortality rate was 18.57%. Thus, it is concluded that the stem rooting of Erythrina
crista-galli L. is influenced by the type and age of the cuttings, and the application of IBA is
irrelevant to the rooting percentage.
