We studied how light from different light sources influences germination and postgerminative growth of plants from somatic embryos and seeds of Norway spruce (Picea abies [L.] Karst). Somatic embryos of three spruce genotypes and seeds were subjected to light from commercially available light sources: Philips TLD Blue 18W/18 (BL), Osram Fluora (FL), Philips Cool White TL 50W/33 (CW), Osram Warm White 18W/30 (WW), Philips Yellow 36W/16 (YE) and Philips TLD Red 36W/15 (RE), 18 h a day, with a… CONTINUE READING
