Cyanobacteria has a highly
diversity group that consists of photosynthetic prokaryotic microorganisms.
Cyanobacteria that produce lots of metabolites such as amino acids, proteins,
vitamins etc. have a wide spread. In this study, the effects of different concentrations
of Spirulina platensis extracts on
the germination of wheat and barley seeds and root-stem length, lateral root
number and fresh-dry weight were investigated. The application of S5 (100% cell
extract) showed an inhibitory effect on seed germination on both wheat and
barley. S2 (25% cell extract) and S4 (75% cell extract) applications had a
positive effect on germination and seedling development in wheat. In barley, S2
(25% cell extract) application activated germination and seedling growth and
other concentration applications did not create a positive effect. As a result;
cyanobacterial extract has positive effects on seed germination and plant
growth-development and it is possible to produce a commercial and ecological
biostimulant by developing different extract concentrations.
