Аннотация: In this investigation the working out and the standardisation of the x-ray contrast method for determination of the germinability of Picea abies (L.) Karst. seed is described. 84 samples from different countries and with various germination values were used for the study. Treatment of a sample with a 40 per cent solution of sodium iodide for 15 minutes at room temperature was found to be suitable for calculating its germinability
