摘要：

The sowing qualities of the seeds of Abies sibirica Ledeb. from trees of I to V Kraft grades and the total content of nitrogen in the seeds were determined. The best qualities are found in the seeds taken from the middle part of the cones growing in the upper part of crowns of trees of I and II Kraft grades. The 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.
