1. A method for automated objective evaluation of germination properties of plant seeds and of seedlings developing from the plant seeds, comprising: providing the plant seeds in a dense medium, including filter paper or soil, as a germination substrate; examining at least one of the plant seeds or developing seedlings a plurality of times in said dense medium using at least one imaging computer tomographic process to obtain three-dimensional, time point-related examination data ( 400 ) from a plurality of cross-sectional images according to a sequence of time during germination of the plant seeds into the seedlings; segmenting the three-dimensional, time point-related examination data ( 400 ), and allocating the segments ( 516 - 519 ) obtained to anatomical units of the plant seeds or seedlings, the anatomical units of the seedlings including one or more of the following: radicle, hypocotyl and cotyledons of the seedlings; and determining time point-related anatomical features (x, y), in the form of at least one of a volume, an area, and a dimension of the anatomical units of the plant seeds and seedlings from the allocated segments ( 516 - 519 ).
