ARTIFICIAL AGING OF VICIA-FABA L SEEDS CAUSED BY PROLONGATION OF G-1-PHASE

Broad bean (Vicin faba L.;'Inovec'') seeds were artificially aged by m eans of storage at 30 %, resp. 25 % water content at 25 degrees C for 7-days to study the consequences on germination, root length and frequ ency of chromosomal aberrations. Under these conditions, significant c hanges in all parameters were observed. An increase of frequency of ch romosomal aberrations in ana-telophase cells was confirmed by evaluati on of c-metaphase cells. Synergic effect of artificial seed ageing was studied on different harvests of old seeds. Possible principles of th is effect on cell level are discussed.
