FIELD: agriculture.SUBSTANCE: invention relates to agriculture. Evaluating biological activity of preparations for improving sowing properties of grain seeds, identical weights of compared seeds are placed in cups, filled with sand in an amount which is 4 times greater than weight of seeds, and water is added to ones, and solutions of tested preparations-stimulants - to others, held and carbon dioxide concentration is measured in vessels with compared seeds. Higher value of carbon dioxide concentration characterises best sowing quality of seeds and quality of stimulant preparation.EFFECT: invention allows evaluating biological activity of stimulants for seed sprouting and solve task of selection of stimulant preparations for presowing treatment of seeds.1 cl, 1 dwg, 5 tbl, 4 ex |
