FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Identical suspension processed and unprocessed preparations-stimulators of seeds are placed in a closed container filled with sand in an amount in 4 times greater than the weight of seeds, and added to the capacity equal to weighed portions of seeds amount of solutions of soil solutions, recovered from soil pastes, maintained and carbon dioxide concentration is measured, released at one central corn seed in germination of seeds in contact with soil solutions at room temperature during 16-28 hours in containers with compared seeds. Higher value characterizes the best sowing quality of seeds and quality of preparation-stimulator.
EFFECT: invention allows evaluating biological activity of promoters of seed germination and solving problem of selection of preparations-stimulant for presowing treatment of seeds.
