Abstract

The influence of the cyanobacteriumNostoc muscorumon vital activity of barley seedlings of the species Novichok was researched. In the experiments different ways of cyanobacterial treatment were used: introducing microorganisms in the growth medium and pre-sowing inoculation of barley seeds with cyanobacteria. The influence of cyanobacterial treatment on biochemical indices and linear growth of barley plants was assessed. The share of plastid pigments and intensity of the processes of lipid peroxidation were assessed in a spectrophotometric way, standard methods were applied. It was stated thatNostoc muscorumhas a phytostimulating effect which consists in inhibiting oxidation processes in barley cells, accumulating substances with antioxidative activity, and activating growth processes. Pre-sowing inoculation of barley seeds with cyanobacteria is the most effective one.

Highlights

Cyanobacteria (CB) is a group of gram-negative morphologically various procaryotes, they include one-celled, colonical, and filamentary forms
Cyanobacterial symbioses can be of different types: epithytical (CB concentrate on outer surfaces), which is typical of the genus Nostoc with the moss (Sphagnum); endophytic (CB concentrate within intercellular spaces), which is typical of Nostoc or Anabaena with some mosses, ferns, and gymnosperms; intracellular (CB concentrate within filaments or vesicles), for example, Nostoc with herbaceous plants of the genus Gunnera [1, 2]
Such cyanobacterial and plant complexes are less vulnerable to unfavourable influence of the environment [4, 5]

Summary

Introduction

Cyanobacteria (CB) is a group of gram-negative morphologically various procaryotes, they include one-celled, colonical, and filamentary forms They are the most ancient organisms upon the Earth and they are ubiquitous, they live everywhere, including hot springs, water bodies and soils of different type, even polluted ones. Such cyanobacterial and plant complexes are less vulnerable to unfavourable influence of the environment [4, 5]
