Abstract: A method for monitoring and/or calibrating a device designed for three-dimensional X-ray optical inspection of seedlings in different growth phases may optically or X-ray optically measure natural seedlings in three dimensions at predetermined times during their growth phase. The method may create a control program for a device which is designed for the three-dimensional printing of artificial seedlings as reference samples which are replicas of the natural seedlings in each case using the recorded measured values. The method may also produce artificial seedlings with a plastic using the device in accordance with the created control program. The artificial seedlings thus produced may be measured three-dimensionally by X-ray optics and the measured values thus acquired may be recorded in a control chart or an already created control chart is adapted, with which control chart monitoring and/or calibration of the device designed for the three-dimensional X-ray optical inspection of seedlings is performed.

Abstract: A device for arranging seed includes a container with a container wall having an upper edge and a lower edge at a perpendicular distance from one another, a germination paper extending along the inside of the container wall, and a retaining device which cooperates with the germination paper in such a way that the seed is carried on the germination paper at or above an intermediate height above the lower edge and below the upper edge of the container wall in such a way that germs of the seed can grow upwards and roots of the seed can grow downwards.

Abstract: The invention relates to a method for evaluating germination properties of plant seeds and/or of sprouts developed from the plant seeds, on the basis of anatomical characteristics (x, y) at a particular point in time, wherein determining the anatomical characteristics (x, y) at a particular point in time comprises analyzing the plant seeds and/or sprouts using at least one imaging method and obtaining three-dimensional analysis data (410) at a particular point in time, segmenting the analysis data (400) at a particular point in time and associating segments (516-519) thus obtained into anatomical units of the plant seeds and/or sprouts, and determining the anatomical characteristics (x, y) of the anatomical units of the plant seeds and/or sprouts at a particular point in time from the associated segments (516-519) at at least one point in time.

Abstract: The present invention concerns a method for classifying (704) objects (3) contained in seed lots, in which characteristics of the objects (3) are determined using at least one non-invasive process (702, 703), wherein a light-sectioning procedure (702), by means of which the objects (3) are three-dimensionally recorded and at least one spatial characteristic of the objects (3) is determined, is used as at least one non-invasive process (602, 603), and wherein characteristics which have been determined by the laser light-sectioning procedure (702) or by the laser light-sectioning procedure (702) and at least one further non-invasive process (602, 603) are used jointly for describing the objects (3) to perform the classification.
