Possibility of natural reforestation hearth root fungus

Objective: the study within 5 years of the processes of differentiation of pine trees and natural regeneration of forests in the dieback of trees from root sponges. Material and methods research. The research was conducted in the period between 2010 and 2014 in 6 existing dieback. The lesions had a rounded shape with an average diameter of 41 m. For comparison, Melchakova space was laid a control area with similar homes characteristics the size 35×40 m, comparable in size to the dieback. On each control area and each of the foci drying was carried out solid are very rare trees with their division 6 status categories. The average area of the lesion and control area amounted to 0.14 ha, the average number of trees at each of them is 100 PC. Results. Within 5 years the number of healthy trees in the control areas decreased from 45 units in 2010 to 40 in 2014 At the same time in the dieback the number of healthy trees decreased with tree 41 in 2010 to 14 in 2014In dieback and, especially in the Windows of the canopy may produce an ample amount of mixed-age self-sowing and undergrowth of different wood species. In the surveyed forest cultures a marked increase in the number of self-seeding pines in dieback as they evolve from emerging (2010) to progressively existing (2014). Conclusion. In the process of differentiation of trees in the dieback remains a certain number of trees without signs of disease, indicating their resistance to infection. Healthy pine trees in the centers of the root sponges can serve as a good gene pool for natural regeneration of the forest. In the dieback as they progress, formed a certain amount of self-sowing and undergrowth of tree species.
