Abstrakt
Lower content of hexane extractable lipids and much higher acidic number of this fraction were found in seeds subjected to long-term storage than in seeds of respectively shorter period of storage. No significant differences in lipid content were found between seeds of different resistance to the accelerated aging test (Machaniceka). There is a possibility to lower the seed-moisture with the vacuum dehydration method down to 1 % without loss of seed vitality. Common use of this method in the storage practice enables significant extension of the preservation period of seeds of spruce or other forest tree species.
