Antagonistic Activity of Bacterial Association of Apple Shoots Against Phytopathogenic Fungi

Microbial associations on surfaces and internal environment on shoots of apple sorts Golden Delicious, Wealthy and Berkutovka with symptoms of fungal infections were studied. 195 strains of epiphytic and endophytic bacteria, of which 8 strains had marked antagonistic activity against phytopathogenic fungi Alternaria alternaria, Aspergillus tubiengensis, Fusarium incarnatum equiseti, Fusarium tricinctum and Phoma fungicola were isolated. Antagonistic bacterial strains are identified as Bacillus amyloliquefaciens SA77, B. badius SA68, B. gibsonii SA104, B. methyloprophicus SA94, B.

Effect of Exopolysaccharides of the Bacterium Paenibacillus Polymyxa 1465 on Growth and Defense Responses of Wheat

Authors: Konnova S. A., Ignatov V. V., Konnova S. A.

Rhizobacteria of the genus Paenibacillus promote plant growth and induced systemic resistance to diverse environmental stresses. Here we present the results for the effect of exopolysaccharides (EPS) obtained from growth of Paenibacillus polymyxa 1465 with different carbon sources on the early stages in the development of wheat (Triticum aestivum L. cv. Saratovskaya 29) and on the peroxidase activity in wheat seedling tissue.

Light Influence on Morphogenesis Wheat

Authors: Strapko A. M., Kasatkin M. Y., Stepanov S. A.

In work results of research morphogenesis wheat are presented at presence or absence of the light factor. Influence of light on growth of all leaf shoot, activity of a cone of increase and growth of germinal root system of a seedling of wheat is established. In the presence of the light factor growth epicotyl begins with the moment of the termination of growth coleoptile. Growth epicotyl occurs synchronously to growth of a sheath of 1st leaf. In the absence of light growth coleoptile and epicotyl proceeds and after end of growth of a plate and a sheath of 1st leaf.
