Broad bean (Vicia faba L. “Inovec”) seeds were artificially aged by means of storage at 30 %, resp. 25 % water content at 25 °C for 7-days to study the consequences on germination, root length and frequency of chromosomal aberrations. Under these conditions, significant changes in all parameters were observed. An increase of frequency of chromosomal aberrations in ana-telophase cells was confirmed by evaluation of c-metaphase cells. Synergic effect of artificial seed ageing was studied on different harvests of old seeds. Possible principles of this effect on cell level are discussed.
