Abstract
Invention is the innovative apparatus to determine plant seeds quality rate in a dormant stage. Aim of the invention is measuring quantity of carbon dioxide radiance on active seeds to calculate average of the germination, the vigor, and a proportion of the value of the light radiated seeds to calculate viable. Apparatus use process of the spectral lighting to warm up seeds to obtain thermal contrasting Infra-red images, to visualize seeds embryos metabolism. The contingent seeds embryos intensity of the radiance is taken in account to determine seeds measurement of the viability, of the vigor indicative. Due to order to create the specimen seed embryo radiometric profile data, recording digital images of the seed unit's specimen data enable to derive, and then calculate the Infra-red contrast value of seed specimen profile. Light titrations of the seeds thermal exposition, due to seeds specimen rotation, eliminate irregularity of the seed layer lighting.

Description
DETAILED DESCRIPTION OF INVENTION
[0005] Invention, an apparatus for the contrasting thermography as shown on the FIG. 1, includes 1, halogen quartz lamp, lamp pointed directly to light up the circularly rotating base for the light titration, motorized turntable 2. The seed specimen resided on the motorized turntable surface layer for light exposition and titration. A plant seeds specimen exposing to the quartz lamp through the emitted light thermal stream, to light up plant seed cluster in a contrast .sub.I, given by formula (1), to create contrasting .sub.L. (layer-seed surface) of the thermal profile given by equation (2), as shown in the FIG. 2. The light titration technique, seed specimen rotation, eliminate irregularity of the light source to provide identical exposition of each seed units in an equal rotating treks. Thermal image camerathe longwave imager 3 pointed to the seed specimen to acquire the record of the radiometric data image, immediately after exposure to the light stream from quartz lamp 1, as shown on the FIG. 3. The thermal radiance aperture of the CO.sub.2 band spectrum of the seeds recording, and measuring by thermal imager, longwave camera to create a thermal profile of the specimen seed unit, to determine radiance contrast values by given formulas (1), (2) as shown on the FIG. 4. Apparatus, calibrated in a CO.sub.2 spectrum, support measure of the concentration profile of the CO.sub.2, as a product of seed metabolism. Seed unit physical property, the thermal image profile, depict the layer-seeds surfaces radiance intensity contrast in proportion to the CO.sub.2 concentration in a dormant seed. Seed metabolism presented through the embryo radiance image. The active seed status, indicated by the CO.sub.2 radiance, is determine the selection of the viable gradation seed for a dormant stage. Positive value of the seed/layer contrast 1 indicate dormant seed viability, instead negative rate of the seed/layer contrast <1 is a sign of a nonviable seed. Average of the radiance distributive allow measure of the CO.sub.2 concentration value to determine the vigor of the seeds specimen. The dormant stage seed longwave radiance intensity value there has engaged as indicator of the plant viable.
