Abstract

The established correlations between geometric and gravimetric parameters of varietal seeds of Scots pine are characterized by varying degrees of dependence. A close correlation was found between the surface area and the volume of the seed (correlation coefficient С.V. = 0.89), the length and surface area of the seed (С.V. = 0.88), the width and surface area of the seed (С.V. = 0.88), the width and volume of the seed (С.V. = 0.81), the weight and volume of the seed (С.V. = 0.80), the thickness and volume of the seed (С.V. = 0.77), the length and volume of the seed (С.V. = 0.75), the weight and surface area of the seed (С.V. = 0.72). A moderate correlation was revealed between the parameters of seed mass and length (С.V. = 0.64), seed mass and width (correlation coefficient 0.62), seed mass and thickness (С.V. = 0.59), seed length and width (С.V. = 0.55). A low level of correlation was established for such parameters as the thickness and width of the seed (С.V. = 0.41) and the thickness and surface area of the seed (С.V. = = 0.40). For the entire sample of varietal seeds, there is no correlation only between the parameters of the length and thickness of the seed (С.V. = 0.29). The main sowing qualities of the seeds of the Pine ordinary of sort Negorelskaya were determined (weight of 1000 seeds – 6.39 g, seed purity – 96%, technical germination of seeds – 88%, seed germination energy – 80%, the average seed rest of the seeds is 5.5 days) and the moisture content of the seeds is 5.8%.
