Abstract
Sowing qualities of the seeds of Abies sibirica Ledeb. from the trees of I to V Kraft grades and total content of nitrogen in the seeds were determined. The best qualities characterize the seeds taken from the middle part of the cones growing in the upper part of crowns of the trees related to I and II Kraft grades. Nitrogen content in the seeds varies within the range 2,7–3,46 mg/g and depends on the growth and development of the trees. The correlation between these characteristics was found to be 0,81–0,94.
