Abstract
Effects of different combinations of short days and dark treatment and different light intensities during the short days on in vitro tuberization of three potato cultivars were examined. Tuberization in Desiree, Cleopatra and Gracia was induced by short-day-treatment after 4 weeks culture under long days. To pre- serve natural endogenous hormonal balance of in vitro plantlets growth regulators were not added to the medium. The shorter the duration of short-days period the higher light intensity necessary for earlier tuber initiation. There was also a synchronizing effect of the high light intensity on tuber initiation but it depended on photoperiod-treatments and genotypes. The higher the light intensity during induction peri- od the less favourable the effect of light applied after the induction period.
