Critical velocity of transportation, basic dimensions (length, width and thickness) as well as the mass of parsnip seeds was determined. Based on the measurements which were carried out, a geometrical hydraulic diameter, proportion index, spherical index and unit mass were calculated. A test of seeds germination was carried out by checking out the effects every 12 hours and then appropriate value of the germination time index was assumed to each seed. The above features and indexes were compared with the use of t test for independent tests and the correlation analysis. It was stated that germinated and non-germinated seeds differ statistically significantly only on account of their thickness. Some improvement of the germination ability of the seed material may be obtained by separating lighter seeds therefrom. In the tested seed material, obtaining 65% of germination ability was related to losses of seeds, which correctly produce sprouts at the level of approx 27%.
