Moreover we have revealed some strains possessing the ability to stimulate simultaneously roots formation and growth of coleoptiles. These are strains Streptomyces sp. 503
7, Streptomyces sp. 9, and Streptomyces sp. 42. Besides that, these strains cause an increase in length and weight of primary rootlets. Previously we have shown that some other Streptomyces strains from the same soil samples have the ability to stimulate growth of maize seeds (Boortseva et al., 2006, Maslobrod et al., 2009, 2010). Therefore, on triticale seeds, with the use of the new Streptomyces strains, it was shown once again the specific activity of Streptomyces strains from different soil samples on plant objects. CONCLUSIONS Thus, it was reviled that the metabolites of Streptomyces isolated from soils of Moldova significantly influence the process of seeds’ germination, which is reflected in growth stimulation of roots and coleoptiles, as well as in increasing of rootlets’ weight. This allows considering the studied strains of Streptomyces to be potential producers of growth regulators for plants. Biopreparations created on their basis can be successfully used in crop production. REFERENCES Aldesuquy H.S., Mansour F.A. and Abo-Hamed S.A., 1998.
