In the article, new data of the influence of salts of zinc in doses of 40 mg/kg and 60 mg/kg on haemopoetic cells of a red marrow of a bird at ultra structural level are presented
The researches of degradation of oil products in fresh-water reservoirs at the expense of the activity of petrooxidizing bacteria of Acinetobacter speivs SN-2 are carried out. The decrease in the content of oil products in 25 days prior to maximum concentration limit (0,05 mg/l) and the increase in concentration of oxygen in the reservoir are defined
The article features a basic algorithm for determina-tion of tree health classes in terms of park planta-tions, which will reduce the effect of an expert's sub-jective judgment on the survey results
An important element in the technology of growing
seed plants of onion is the use of physiologically active
substances to protect plants from frost in early spring
growing season. Damage to plants during this period
affects seed production. In the experiment we used
preparation called Epin-Extra R, with which the leaves
of plants were treated a day before expected frost. Test
results have shown high efficiency of preparation in the
field and in the film unheated greenhouse. Treatment
helps to balance the negative impact of low
temperatures and obtain an additional seeds yield 92-95
kg / ha more compared with the control, due to the
increase of seed of productivity of plants to 3.2 g
The article presents the long-term data (2007-2015.)
biometric aboveground plant parts and the estimation of
the prospects of the three introduced botanical species
of juniper and recommendations for their use in
landscape design. We have established very promising,
promising and unpromising varieties for landscaping in
the conditions of the foothill zone of the Krasnodar
region out of 16 varieties of juniper species: China,
ordinary and rock
In the article it is offered to count the spatial sign with provision for mosaic-tiered structure of wood when estimating rising trees. It is noted that the diameter of stems has mediated (indirect) relationship with average distance to the nearest tree
The research of the territory adjacent to Novocherkassk state district power station, for the content of polycyclic aromatic hydrocarbons (on an example of benzo(a)pyrene) is presented. The benzo(a)pyrene content in soils has been determined with a method of subcritical water extraction. The content of benzo(a)pyrene in soils of the territory adjacent to Novocherkassk state district power station has been estimated. It is shown, that contents of benzo(a)pyrene excess over maximum permissible concentration in soils of five-kilometer zone around the companies
This article presents the results of testing IRAP DNA
markers Cass1 and Cass2 applied to Prunus spinosa.
The findings suggest the high perspectiveness of
their using for the study of genetic diversity of the
gene pool of this species. According to the results of
the analysis of the sample 12 genotypes were
identified from 6 to 13 fragments in the spectrum of
Cass1 and from 5 to 11 fragments for Cass2. As a
result of cluster analysis in the sample formed three
groups of samples. In one of the groups, which is
most distant from the other two, includes samples
taken in Ukraine, while the remaining two groups
included samples from Armenia, the Krasnodar
region region, the Republic of Adygea, Ukraine and
Moldova, and three cultural large-fruited form. The
distribution of samples in clusters corresponded to
their geographical origin that favors the objective
assessment of genetic distances between the samples
using Cass1 and Cass2 markers. Thus, it was
concluded that the prospects of using DNA markers
to study the genetic diversity within a species of
Prunus spinosa
This article discusses the actual problem of using SSR-markers in studies of the genus Prunus. We have examined the works on the most important cultures of genus, collected and analyzed contemporary literature of the subject. Data of the initial stage of Prunus SSR-based genetic diversity study in the North-Caucasian region has been described in the presented publication
The results of study of production process of winter wheat amid of changing of agro ecological conditions such as seeding time, level of initial fertility, fertilizer system and variety throughout 3 year-research are shown in the article. Five hypotethetical systems are pointed out with the help of factorial analysis. Detached varieties and research years are pointed out in terms of their factorial influence
