Total dehydrogenase activity and formation of polyribosomes in embryonic axes and cotyledons of field bean seeds from different harvest years were studied. 3H-uridine incorporation experiments showed that seed ageing was accompanied by decreased capability for RNA synthesis and polyribosome formation. The embryonic axes of seeds with reduced vigor contained lower levels of polyribosomes
