Аннотация: The ultrastructure of three parts (endosperm, rootlets and cotyledons) of aged seeds of Pinis sylvestris L. has been studied. In dry seeds no clear differences resulting from ageing are seen as compared with resting living cells, but during inbibition clear differences are evident. Inhibition of development of the DNA-containing structures, mitochondria and plastids, was the first indication of senescence. Lypolysis usually preceded proteolysis, in contrast to the course of events in living cells.
