In vitro germination of Abricó-de-Macaco (Couroupita guianensis aubl.)zygotic embryos in different culture media and light spectra

ABSTRACT: Couroupita guianensis Aubl. is an Amazonian forest species with important medicinal and ornamental value. This study evaluated the effect of different culture media light spectra on in vitro germination development zygotic embryos C. guianensis. The media, MS WPM, were without addition plant growth regulators associated four LED spectra: white (CW), 70% red + 30% blue (R2B), 100% (R), (B). One hundred percent seeds successfully underwent germination, did not interfere embryo development. In to this, induced morphogenesis R2B treatment significantly promoted production secondary roots. may aid rooting acclimatization seedlings this species.
