The paper presents the results of studies on the effect of calibrating Scots pine (Pinus sylvestris) seeds on the morpho-biological characteristics of seedlings. The studies were carried out in 2017-2019. Scots pine seeds were used as the object of research. In the course of the research, laboratory and field methods were used. The seeds were calibrated using a sieveless separator, which makes it possible to obtain several tens of seed fractions with a size gap of 0.02 mm. It was found that plants of large seeds were characterized by a higher starting growth. Throughout the growing season, the advantage of these fractions persisted. Due to the higher growth rate of small fraction plants, the difference between plants decreased by the end of the growing season. By the end of the first year of vegetation, there was some advantage of large seedlings, the height of which varied from 6.95 cm (second fraction) to 7.18 cm (fourth fraction). The seedlings of these fractions were characterized by the highest uniformity (17.0%). At the end of the second growing season, the most intensive growth was noted in seedlings of large seeds, due to which a large planting material is formed, characterized by high uniformity.

本文介绍了校准苏格兰松（ Pinus sylvestris）效果的研究结果。) 种子对幼苗形态生物学特性的影响。这些研究是在 2017-2019 年进行的。苏格兰松种子被用作研究对象。在研究过程中，使用了实验室和现场方法。使用无筛分离器对种子进行校准，这样可以获得几十个大小间隙为 0.02 mm 的种子级分。发现大种子植物的特征在于较高的起始生长。在整个生长季节，这些部分的优势持续存在。由于小部分植物的生长速度较高，植物之间的差异在生长季节结束时减小。到植被第一年结束时，大苗具有一定的优势，其高度从6.95厘米（第二部分）到7.18厘米（第四部分）不等。这些部分的幼苗具有最高的均匀性（17.0%）。在第二个生长季节结束时，在大种子的幼苗中观察到最密集的生长，因此形成了具有高度均匀性的大种植材料。
