The article considers the enzymatic activity and some other ecological and biological properties of zonal soils of the Crimea (cambisol, Chromic cambisol, different subtypes of chernozems). We have revealed significant differences in catalase, dehydrogenase, polyphenol oxidase, peroxidase,
invertase for soils of the Crimea, which can not be explained only by the content of soil organic matter. Despite the low humus content of the soil, some have a high level of some enzymes. The level of enzyme activity depends on the reaction medium, the content of carbonate and other soil properties. We have also revealed that the agricultural use of brown
soils under vineyards leads to a significant change in their properties and enzymatic activity
The influence of climate factors on adaptiveness of Actinidia deliciosa strange cultivars is ascertained in damp subtropics of Russia. The basic limiting factor of its cultivation is precipitation quantity during flowering phase and fetal maturity
The article analyzes the problems that arise when evaluating biodegradation of materials, items, structures and products in natural environments.. The causes of biodegradations are revealed
In the article, we made an estimation of pine cultures’ (Pinus silvestris L.) sanitary condition in the Savalsky Forestry area of the Voronezh region. The obtained results show their considerable weakness, passing to the drying phase because of pine fungus
Estimation of blast resistance of rice breeding lines, carrying resistance genes Pi-b, Pi-z and Pi-40 has been done. For phytopatological test isolates of pathogen from Krasnodar territory were used. As the results of the study Pi-40 gene showed maximal resistance to blast isolates. On the other part, rice line, carrying both genes – Pib and Pi-z showed significantly higher level of resistance with compare to standart variety Khazar
The possibility of the ISSR-markers application for systematization and genetic certification of the genus Rhododendron is showed on the basis the research of 25 species and intraspecific taxons. The way of recording of genetic passport on the basis of amplicons size is suggested
As result of evaluation 24 common wheat introgression lines with genetic material Agropyron glaucum the considerable variability of resistance to leaf rust was revealed. Genetic control of leaf rust in introgression lines 60 and 109 was studied using hybridological analysis. Both lines contained single dominant genes differed from each other and from the known effective Lr19 and Lr24.
The investigated lines with genetic material Agropyron glaucum are valuable donors of the genes for leaf rust resistance
This article provides an overview of the results obtained on the basis of monitoring heavy metals’ pollution of agrotechnogenic zone in Stavropol. It includes the analysis of more contaminated areas
The article presents the results of the state evaluation of trees and shrubs in landscaping plantings of different types situated in four parks in Petrozavodsk. The species and number of plants in good, satisfactory, and unsatisfactory states were determined. The conducted analysis of species distribution and the number of trees and shrubs in each category of state allows working out the activities for planting reconstruction
This article presents an assessment of the stability of the black soil of the Crimea to contamination with heavy metals (Pb, Cu, Cr, Ni) and oil using biological indicators
