Table 4 shows the mean values of the geometric equivalent diameter \(D_{g}\), the aspect ratio \(R\), and the sphericity ratio \(\Phi\), as well as the unit weight \(m_{D}\) calculated on the basis of measurements of the physical traits of the seeds of the species under analysis. The winter barley seeds with a moisture content of 17.5% were characterized by the highest mean value of the equivalent geometric diameter \(D_{g}\) and unit weight, whereas the lowest values of these parameters were noted in the dressed winter rye seeds with moisture content values of 13.5% and 11.5%. The barley seeds with a moisture content of 11.5% were characterized by the highest mean aspect ratio \(R\). The highest mean value of the sphericity index \(\Phi\) was noted in the dressed winter triticale seeds with a moisture content of 15.5%. The mean values of the seed indexes were similar to the data presented by other authors for these species of cereals [47, 50, 51, 52]. The values of these coefficients, calculated based on the dimensions of the seeds, are significant for various separation processes. They also characterize the shape of the seeds to a certain extent, and their numerical value can be used as a criterion for the selection of seeds.
