ВИВЧЕННЯ БIОРIЗНОМАНIТТЯ КОМПЛЕКСУ ПРОКАРIОТНИХ МIКРООРГАНIЗМIВ ПIДЗОЛИСТИХ ГРУНТІВ

Using the method of DNA cloning the comparative analysis of the complex procaryotic microorganisms of podsolic soils is carried out for a long term cultivation of flax and in bare fallow. The method has allowed to reveal and identify the species belonging, to estimate the biodiversity of soil procaryots on which basis it is possible to judge the soil microbiological communities generated under the influence of various agroreceptions. It is established that finally the permanent culture of plants causes genetic resources degradation of soils microflora and basic change of its qualitative structure. It is directly connected with decreas in stability of plants to natural and anthropogenous stresses. Crop succession of agricultural crops in the crop rotation link causes specific updating of microcenosis.
