[Spreading of fungi of Fusarium Lk : Fr. genus in the soil of mountain-forest reservation of Chatkala].
The species composition of Fusarium genus is more rich and diverse in agrophytocenoses than in natural soils of vertical zones of the Chatkala mountain systems. Soils at the height of 600-700 m were the poorest in the number of Fusarium genus fungi while agrophytocenoses were the richest in the fungi. Certain differences in the species diversity and the number of Fusarium genus were found in the soil of the root zone of plants Poa bulbosa, Juniperus sarevschanica and Festuca valesiaca. The maximum of their development was observed in the alpine soils in summer and in autumn and in alpine soils in spring and in summer. The possibilities of plants affection increase in the period of biological activity of these fungi. Representatives of Fusarium genus are an important component of phyto and agrophytocenoses; they take active part in the processes of soil formation.
