EFFECT OF METABOLIC PRODUCTS OF STREPTOMYCES RECIFENSIS VAR. LYTICUS ON THE VEGETABLES SPROUTS GROWTH
Journal Title: Мікробіологія і біотехнологія - Year 2014, Vol 0, Issue 1
Abstract
Purpose. To study the effect of the preparation P3X of strain Streptomyces recifensis var. lyticus 2435 and supernatant cultural liquid (SCL) of strain Streptomyces recifensis var. lyticus 2R -15 on the vegetables sprouts growth and compare with the action of plant growth regulators emistym and heteroauxin. Methods. Biometric and biochemical changes of sprouts of squashes, cucumbers, tomatoes, radishes for the actions of microbial preparations and plant growth regulators were investigated. Changing of germination energy of seeds, roots length, proteinase, peroxidase, poliphenoloxidase activity was studied. Results. It was shown that the action of SCL and P3X was the most effective for accelerate the growth of sprouts of squashes, cucumbers, tomatoes, radishes. These preparations stimulated germination energy and length of roots on 8–30% and 5–20%. Emistym stimulated only the length of roots on 10–40% and did not affect positively to germination energy of seeds. It was found that heteroauxin inhibited biometric indicators on 12–50%. Stimulation of proteinase activity of seeds was effectively carried by emistim (stimulation in 1.5–5.0 times) and SCL (1.3–2.9 times); peroxidase activity of roots – emistim (1.3–3.5 times) and SCL (1.4–3.0 times); polyphenoloxidase activity of leaves – SCL (1.3–4.0 times) and emistym (1.2–3.8 times). Conclusions. Study of microbial preparations and plant growth regulators of sprouts of vegetables showed that positive change of biometric parameters and enzymatic activities that occur in sprouts is a response to the action of biotic factors and it depends on the a type of preparation and a type of vegetable. Stimulation of biometric and biochemical parameters which was observed for the sprouts after action of preparations SCL, P3X and emistym may be used to accelerate growth of plants.
