Summary: In the paper we study the stability of the pine trees of various forms and categories to the root sponge. The differences in terms of resistance to root sponge trees of pine-trees, depending on the shape of the crown, the type of sexualization shoots, forms and apophis cones.
Аннотация: Изучена устойчивость деревьев сосны обыкновенной различных форм и категорий к корневой губке. Выявлены различия по устойчивости к корневой губке деревьев сосны обыкновенной в зависимости от формы кроны, типа сексуализации побегов, формы и апофиза шишек.

Among infectious diseases, bringing significant damage to pine ordinary forest stand, is the root rot caused by heterobasidion. Infectious beginning of this pathogen is present in almost all plantations of pine-trees. This is due to the long and abundant sporulation fungus, the possibility of the easy transfer of infection for long distances, the ability to grow on the dead vegetation residues and a long time to maintain a viable mycelium. Especially strong distribution of the disease is observed in the pine plantations established on lands emerged from agricultural use.
To identify the forms pine resistant to time-off heterobasidion, a survey was conducted of net 45-year-old pine with damped centers of root rot. Culture created on lands emerged from agricultural use and is currently characterised by relatively good growth and productivity. Forestry and stand characteristics of the forest cultures follows: forest site type – pine stand mossy, the initial density – 7143 pieces per 1 ha, composition – 10P, the average diameter of 18.5 cm, average height is 19.5 m, relative density – 0.7, bonitet class – I, volume of stande – 250 m3/ha. Culture established on the territory of Negorelsky educational-experimental forestry enterprise unit.
