Prace Instytutu Badawczego Lesnictwa, Seria A (937/943): 19-41
The vitality of Norway spruce (Picea abies) seeds collected from 55 trees in Jugow forest district (Poland) were analysed before and after 5 years of storage. Four different storage temperatures were applied: -15, -20, -25 and 3 degrees C. After storage, the vitality was satisfactory in all tested temperatures. Small decrease in germination was observed in seeds stored at 3 degrees C. A small decrease (1000 seeds) in weight was observed in all temperatures.
