The article highlights the main aspects of the use of growth regulators in the cultivation of European larch seedlings by seed. In the research material of the article, laboratory studies were conducted to determine the effect of different concentrations of growth regulators on the formation of germination and germination energy of European larch seeds.
As a result of the research, it was found that the minimum concentration of agrostimulin also increased germination energy by 3.5 % and laboratory germination by 9.6 % compared to the control.
It was determined that the use of higher concentrations of agrostimulin concentrations (1 and 2 ml/l) led to an increase in germination energy by 7.8 % and 11.5 %, respectively, and to an increase in germination rate by 14.7 % and 20 %.
It was found that the concentration of 2.0 ml/l of emistim-C was the most effective, increasing germination energy by 12.1% compared to the control variant, and laboratory germination reached its maximum value at a concentration of 2 ml/l and exceeded the control by 15.9%.
The study revealed that an increase in the concentration of PABA solutions contributes to an increase in germination energy and laboratory germination of European larch seeds. The most pronounced effect is observed at a concentration of 100 mg/l and is 59.6 % and 72.8 %, respectively.
The results of the study show that solutions of Triman-1 in concentrations of 25 mg/l and 50 mg/l have a positive effect on germination energy, increasing it by 9% and 9.9% and laboratory germination of European larch seeds by 12.3% and 13.9%, respectively.
Also in the course of the research, it was determined that excessive concentrations of different types of growth regulators gave insignificant results compared to the control, which indicates the ineffectiveness of their use.
