摘要：

The influence of light quality on the proliferation of embryogenic tissue of three genotypes of Norway spruce (Picea abies [L.] Karst), with different capacities for mature somatic embryo production, was studied. The proliferating tissues were subjected to light from commercially available light sources: Philips TLD Warm White 36W/29, Philips TLD Blue 18W/18, Philips TLD Red 36W/15, Osram L Fluora 36W/77 and Sylvania Far Red 7080, for 18 h a day with the photon flux (PAR) at 30 μmol m-2 s-1. The effect of light quality on the growth of embryogenic tissue was strongly genotype dependent. In genotype 164-4 tissue proliferation was strongly inhibited by blue and red light. Genotype 86:52 reacted in a similar way, but not as strongly as 164-4, whereas the tissue of genotype 186-3 was almost insensitive to light quality and grew fast in all light conditions.
