Abstract

Growth stimulants are substances that provide the growth and development of plants. The aim of this study was to assess the effect of growth stimulants Albit, Energen and Epin-Extra on the cultivation of annual seedlings of Mongolian oak (Quercus mongolica Fisch. ex Ledeb.) in a forest nursery of Primorye Territory. These stimulants were used as a pre-sowing seed treatment in various concentrations of solutions. Control – seeds which have not been treated with preparations. At the end of the growing season, the parameters of seedlings were determined: height, diameter of the root neck, length of the root system, number of leaf blades, leaf surface area and dry mass. It was revealed that the growth stimulator Albit had a more positive effect on the height of seedlings, and Epin-Extra was more effective on the diameter of the root neck. The total dry mass was influenced by Energen. The rest of the parameters were within the control group, or their decrease was observed. In the future, it is planned to study the effect of these stimulants on the subsequent growth of oak seedlings.
