On diurnal mitotic activity in root tip meristem ofPicea abies (L.)Karst

The determination of mitotic frequency was made in two variants: one part of seeds was germinated in darkness, the other-under periodical artificial lighting. The diurnal mitotic activity varied from 6.2 to 13.5 per cent. After germination under periodical lighting two peaks of mitotic activity [at 6°c a.m. and 4°c p.m.] were found whereas after germination in darkness there was only one [at 12°c a.m. or 6°c p.m. in different repeats].
