Due to the increase in the average annual temperature and the increased frequency of forest fires leading to the death of forest plantations, our institute has developed a new method for obtaining oak seedlings characterized by high growth and development rates. Seedlings obtained by the new method are characterized by high growth and development energy accor-ding to such indicators as average annual growth, plant height, stem diameter and leaf surface index. Oak seedlings obtained by the method developed by us can be used in the repair of forest plantations with a high degree of survival and growth rate. Against the backdrop of recent years, the temperature regime on the globe is steadily growing, accompanied by serious consequences for the environment. Every year, forest fires occur in various parts of the world, caused by both weather disasters and human activity, as a result of which very significant areas of forest plantations are lost. Forest fires lead to severe damage, and sometimes to the destruction of forest cover, which affects the atmosphere, soil, hydrosphere, and fauna, it is also worth noting significant losses for human resources [2]. I would especially like to emphasize that, along with forest fires, significant harm is caused by human activities associated with deforestation, many of which are perennial plantations. For the European part of the mainland, one of the most valuable forest species is oak, which is listed in the Red Book of the International Union for Conservation of Nature and is valuable for its wood [1]. Oak plantations are characterized as long-lived massifs, however, the intensity of their growth is extremely low and it takes about 150-200 years to obtain plantations up to 20 m in height, which is an extremely long period [3].
