Abstract
ABSTRACT Fridericia chica (Bonpl.) L. G. Lohmann has medicinal properties and potential for commercial cultivation; however, the propagation characteristics of this species have been poorly evaluated. This study aimed to analyze the length of cuttings, indolebutyric acid (IBA) doses and substrates containing different proportions of cocoa shell in F. chica cuttings. Two experiments were carried out. In the first one, the treatments were basal cuttings of 10 cm and 20 cm in length and four IBA concentrations (0 mg L-1, 2,000 mg L-1, 4,000 mg L-1 and 6,000 mg L-1). In the second experiment, substrates obtained from five proportions of cocoa shell (CS) and expanded vermiculite (EV) compost were tested: 100 % CS; 100 % EV; 50 % CS + 50% EV; 30 % CS + 70 % EV; 70 % CS + 30 % EV. The rooting percentage, sprouting height and dry biomass production were evaluated. The production of F. chica seedlings can be performed by basal cuttings with 20 cm in length, which allow achieving a rooting rate of 91 %. The ideal IBA dose to obtain a maximum sprout length is 3,600 mg L-1. Mixtures composed of 50 % CS + 50 % EV and 30 % CS + 70 % EV were the best substrates for the production of F. chica seedlings.
Highlights
IntroductionThe species is used in folk medicine as an anti-inflammatory, healing and anti-anemic agent, as well as for the treatment of intestinal colic, hemorrhage, diarrhea and leukemia (Behrens et al 2013)
This study aimed to evaluate the effect of indolebutyric acid (IBA) concentrations and substrates with proportions of cocoa shell and vermiculite on the rooting of F. chica cuttings
In the first experiment, which evaluated the length of cuttings and IBA doses, a significant interaction between the factors was observed only for the variable sprout length
Summary
The species is used in folk medicine as an anti-inflammatory, healing and anti-anemic agent, as well as for the treatment of intestinal colic, hemorrhage, diarrhea and leukemia (Behrens et al 2013). Ferreira et al (2013) carried out the chemical characterization of F. chica leaf extract and evaluated its antimicrobial activity against Salmonella typhimurium, Lactobacillus acidophilus, Escherichia coli and Shigella sonnei bacteria, and the results showed that the classes of secondary metabolites (triterpenes, steroids, saponins, tannins, phenols and flavonoids) identified in the leaves of this species have medicinal potential, mainly as anti-inflammatory, antimicrobial and healing agents. Despite being a species with a great therapeutic value, F. chica has not yet been commercially The species is used in folk medicine as an anti-inflammatory, healing and anti-anemic agent, as well as for the treatment of intestinal colic, hemorrhage, diarrhea and leukemia (Behrens et al 2013).
