Seeds of Norway maple ( Acer platanoides L.) differing in water content (10, 20 and 30%) were stored for 6 weeks at 20 to 30°C. During this period changes in phospholipids and fatty acids as well as in seed viability and germination capacity were studied. A considerable decrease in the phospholipid content was observed, which depended on the water content in the seeds and was related to the decrease of the seed germination capacity. The level of linoleic (18:2) and linolenic (18:3) acids in the phospholipid fraction decreased considerably in the course of the accelerated seed ageing. The results obtained suggest that phospholipid degradation and peroxidation of unsaturated fatty acids, followed by membrane destruction, play a considerable role in maple seed ageing.
