The authors study the effect of growth regulators on seed germination of Larix gmelinii
(Rupr.) Rupr. in the laboratory. These are: salicylic acid and the chemical preparation
“Zircon”. They found out two concentrations of salicylic acid: 10-3M and 5*10-4M to low
germination time parameters of larch seeds. Seed treatment with chemical preparation
“Zircon” (0.02 ml / l) and mixture of “Zircon” with salicylic acid does not affect to the speed
of seed germination. The authors put their attention on analysis of sequence of morphogenetic
stages of seedling growth and got data on existence of salicylic acid stimulation activity for
the root and stem growth with all concentrations tested, but the most pronounced effect was
observed at concentrations of 5*10-4 and 10-4M. Also they study the effect of seed treatment
with salicylic acid and “Zircon” on content of chlorophyll in seedlings. Salicylic acid in a
concentration of 10-3M contributed to the increase of chlorophyll A, but reduced chlorophyll B. Total chlorophyll content increased by the “Zircon”. Combined use of growth regulators
is accompanied by some reduction in the content of chlorophyll A and content increases
of chlorophyll B. The authors mark the increasing of activity of catalase by 37–50 % in
seedlings grown from seeds treated with salicylic acid and “Zir con”.
