摘要
Tests of new natural non-polluting regulators of growth Verva （vegetative terpenoids from Abies sibirica） and Larixin （vegetative flavonoids from Larix） on growth, development and productivity of fibre flax are conducted. The level of phytohormones in vegetating plants （IAA, ABA, zeatine and zeatinriboside） is studied. Preparations stimulate germination of seeds and growth of plants. Field experiment fixed yield increase of flax straw and the seeds of flax-fibre with the use of growth regulators. Industrial experiment represents VERVA product effectiveness on yields increase of flax straw, seeds and flax fiber output.
