THE INFLUENCE OF LIGHT QUALITY IN THE in vitro CULTIVATION OF Cattleya crispata

ABSTRACT: Micropropagation technique is a valuable alternative for high quality genetic preservation of endemic species such as the orchid Cattleya crispata from “Campo Rupestre Ferruginoso”. This study aims to evaluate influence light on in vitro multiplication and elongation phases, offering new insights limiting factors C. crispata. Seeds extracted capsules were used inoculation culture medium. Four sources evaluated culture, namely: fluorescent lamp, white LEDs, red LEDs red/blue LEDs. Data about number shoots, shoot length, shooting vigor pigment content assessed at 90 days culture. Based recorded results, are most suitable ones phases It offers higher seedling production increases chances conservation species. Keywords: ‘Campo Ferruginoso’; propagation; wavelength;
