METHOD AND APPARATUS FOR PRESOWING TREATMENT OF PLANT SEEDS Russian patent published in 1998 - IPC

FIELD: plant growing, in particular, changing of hereditary characters of one plants by the action of biological radiation of other plants. SUBSTANCE: method involves measuring biological radiance flux density of germinating control seed of plant-emitter within wave length spectral range of 2 micron to 2 mm; determining time interval from swelling termination moment to the moment at which radiation flux density drop is observed upon reaching second maximum value; providing electromagnetic informational stimulation of plant-recipient seeds from plant-emitter seeds from the moment swelling process has ended during mentioned time interval, with seeds being isolated from action of ambient electromagnetic fields by shielding chambers. Apparatus has shielding metal chambers formed as hollow thin-walled elliptical shells with internal reflective surface. Shells are disposed in parallel one with another in common plane on common base, with larger axis of each shell being perpendicular to plane at which shells are disposed on base. Each shell has throats at its top and capsule disposed in one of throats and adapted for receiving germ of plant-emitter and arranging it in one focal plane of shell. Other throat is formed as elliptical shell cut made at the level of other focal plane so that concentrated radiation of plant-emitter germ is directed on seeds of plant-recipient. Plant-recipient seeds are disposed on flat metal pan adjoining shell cuts. EFFECT: increased efficiency, simplified construction and method and increased productivity of treated seeds. 5 cl, 2 dwg
