Aging in Pinus sylvestris L. seeds: changes in viability and lipids

Aging of Seats pine seeds (Pinus sylvestris L.) leads to changes in seed qu ality, such as loss of germinability, delayed growth and abnormality in dev eloping seedlings. The knowledge of biochemical changes responsible for the se aging processes is plentiful in some seeds, which are of world-wide inte rest, but for pine seeds these studies are rare. The aim of the present stu dy, mras to analyse pine seeds of varying ages in order to identify biochem ical changes occurring in aged pine seeds, and to see if a correlation exis ted between these results and traditionally used seed-quality parameters, s uch as germinability and electrolyte leakage.
