Abstract
ABSTRACT: Couroupita guianensis Aubl. is an Amazonian forest species with important medicinal and ornamental value. This study evaluated the effect of different culture media and light spectra on the in vitro germination and development of the zygotic embryos of C. guianensis. The culture media, MS and WPM, were evaluated without the addition of plant growth regulators and were associated with four LED light spectra: white (CW), 70% red + 30% blue (R2B), 100% red (R), and 100% blue (B). One hundred percent of the seeds successfully underwent in vitro germination, and the culture media did not interfere with embryo development. In addition to this, the different light spectra induced in vitro morphogenesis and R2B treatment significantly promoted the production of secondary roots. This effect may aid in the rooting and acclimatization of seedlings of this species.
Highlights
Couroupita guianensis Aubl., known in Brazil as the Monkey-Apricot, is a species of medicinal plant from the Amazon and is popularly used as a potent anti-inflammatory agent, administered through infusions made from its leaves, flowers, and bark (PINHEIRO et al, 2010)
In some countries, such as India, it is widely used as an ornamental plant known as the Cannon Ball Tree
Tissue culture is a tool that could contribute to the multiplication of this species
Summary
Couroupita guianensis Aubl., known in Brazil as the Monkey-Apricot, is a species of medicinal plant from the Amazon and is popularly used as a potent anti-inflammatory agent, administered through infusions made from its leaves, flowers, and bark (PINHEIRO et al, 2010). This study investigated the effect of different culture media associated with different spectra of LED light on the in vitro germination and development of C. guianensis embryos. No significant differences were observed between the culture media for most of the characteristics evaluated in the C. guianensis embryos (Table 1). A different effect was observed in studies with native plants such as baru (Dipteryx alata Vog), cajú do cerrado (Anacardium othonianum Rizz), and caçari (Myrciaria dubia Kunth), which evaluated different concentrations of salts and culture media in the in vitro development of explants from these species. In vitro germination of Abricó-de-Macaco (Couroupita guianensis aubl.) zygotic embryos in different culture media and light spectra. The combination of the spectra in the R2B treatment favored the greater formation of secondary roots during the in
