ON SOME FEATURES OF ECOMORPH COMPOSITION OF PLANTINGS WITH DIFFERENT GENETIC WAYS IN URBAN ENVIRONMENT

The features of ecomorph specters for urban plantings (including cenomorphs, hygromorphs and trophomorphs proposed by A.L. Belgard) in forest-steppe continental conditions are considered in the paper. Leading tendencies for plantings ecomorph composition changes in urban environment are discussed.

A COMPARATIVE ANALYSIS OF THE EFFECT OF DIBAZOLE AND 1-CYANODIBAZOLE ON THE MORPHOFUNCTIONAL CONDITION OF LEUCOCYTES

The effect of dibazole and its new analog 2-benzyl-1-cyanodibazole on the rat white blood is studied. Results of the comparative analysis of leucocytary responses to azoles indicate a preliminary activation of non-specific resistivity of the organism. More pronounced response is highlighted after the application of 1-cyanodibazole.

SOIL MICROFLORA AS INDICATOR OF FORESTGROWING CONDITIONS

An ecotrophic connection of the soil microflora and the leaf-litter at the eight forest phytocenoses in the low terrase and the arena of Samara river in Krasnosamarskoye forestry (on the Volga dependent), which are diferred by the planting of trees and forestgrowing conditions, is researched. The everyday microorganisms numbers dynamics of the three size groups and soil respirations under the influence of aqueous extracts from the native and unnative for the researching soils coniferous litter is explored. The data prioritate for the soil indication of the planting of trees and forestgrowing conditions are revealed.
