DURATION OF THE MITOTIC CYCLE IN THE APICAL BUD OF RUDBECKIA BICOLOR

Authors


Summary

Duration of the mitotic cycle and its component phases is estimated in the different regions of the apical bud of Rudbeckia bicolor by means of pulse-labelling with tritiated thymidine and autoradiographic techniques. The average length of the mitotic cycle is around 30–33 hours in all regions of the bud, except in the central zone where it is far longer.
