The use of complex treatment of corn seeds with oligochitosan and melanin to stimulate growth processes.

Pre-sowing treatment of seeds of hybrid Polesskiy 185 with aqueous solutions of oligochitosan (OX) with molecular weight (MW) 28.6 kDa, melanin from chaga, and their complex was used to stimulate the growth processes of corn in laboratory experiments. Treatment of seeds with oligochitosan solutions with concentrations: 0.0005%, 0.001%, 0.005%, 0.01% stimulated an increase in the mass of seedlings and root growth. Melanin also stimulates growth processes. Complex treatment of corn seeds with oligochitosan in combination with melanin has the maximum stimulating effect on the morphometric parameters of seedlings. Stimulation of the growth processes of corn seedlings under the influence of the studied substances is associated with an increase in the synthesis of steroid phytohormones. [ABSTRACT FROM AUTHOR]
