- Аннотация: Treatment of Polessky 185 hybrid maize seed with 0.001% aqueous solutions of oligochitosans ( OC ) with molecular weights ( MW ): 6.9 kDa ; 18.4 kDa ; 28.6 kDa stimulates root growth and increase in mass of seedlings. Oligochitosan with MW 28.6 kDa had the greatest elicitor activity.Treatment of seeds with 0,001% OC aqueous solutions with varying degrees of acetylation (AD): 7.0 %; 9.7 % ; 16.4 % ; 34.7 % led to an increase in the total mass of seedlings, regardless of AD. Analysis of metabolites content using GC-MS in methanol extracts of the roots of corn on the 14th day of the vegetation showed, that the seeds that were processed with OC with MW 28.6 kDa and AD 28.3% showed relative increase of the content of intermediate metabolites of hormone synthesis pathways: brassinosteroids , abscisic acid.
