Abstract – The influence of treatment of millet (Panicum miliaceum L.)
seeds with the solutions of salicylic and succinic acids on the heat
resistance of plantlets and activity of antioxidant enzymes –
superoxide dismutase (SOD), catalase and peroxidase – in them have been
investigated. In the micro-field experiment the influence of these
acids on the millet yield was estimated. The action of salicylic (10
μM) and succinic (1 mM) acids caused the increase of plantlets
resistance to the damaging heating that expressed in the rise of
relative quantity of survived plantlets in 5 days after heating at the
temperature of 47°С and in the reduced content of lipid peroxidation
product malonic dialdehyde during the poststress period. The increase
of activity of SOD, catalase and peroxidase took place in millet
plantlets under the influence of salicylic and succinic acids. The
increase of productivity of millet grain under the action of salicylic
and succinic acids on 13,3-52,0 and 6,4-38,8% respectively depending on
weather conditions in the field experiments was noted.
