METHOD OF OIL-PRODUCING PLANTS GROWTH AND DEVELOPMENT STIMULATION

摘要

FIELD: agriculture. SUBSTANCE: method involves applying gibberellin growth regulating agent "Gibbersib" on vegetating plants at the dose 10-40 g/ha that contains 42-50% gibberellin sodium salts. Plant treatment is carried out by spraying (0.005-0.01% aqueous solution, 400 l/ha) or by aerosol generator at controlled particle dispersity (2-4% solution, 0.5-1.5 l/ha). Treatment is carried out preferably at the phase of head formation (rosettes)-flowering onset. Method provides sunflower yield increase by 4-5 centers/ha (12-15 %), oil content in seeds by 3-13 absolute %. The corresponding values for rape: 47% and 2.5-2.8%. EFFECT: improved method, enhanced effectiveness and biological effects.
