Gorczanski (winter rape) and cv. Mlochowski (spring rape), grown in vitro, were subjected to direct electric current (DC) of different polarity, duration and voltage. The positive orientation of DC, i.e. anode attached to the apical part and cathode to the medium, markedly enhanced the differentiation of the apical meristem in winter rape. The reverse polarity was without effect. DC treatment of positive polarity resulted in spring rape in transition of all explants to generative state while 70 % of non-treated plants remained at vegetative stage. Even negative orientation of DC brought about a rise in percentage of flowering plants with regard to control. The developmental effects of DC were dependent only to a low degree or not at all on duration and voltage of the treatment.
