In this article we have shown the results of studying of biologically active connections in bentonite clays, carotene containing raw materials for the purpose of receiving functional feed additive for agricultural birds
The article considers the multiple use of lagenaria or bottle gourd in different countries of the world. It presents the information of the different types of lagenaria that in each country have their own purposes. Attention is paid to the origin of culture, in this
context, considered a variety of the use of culture. A distinctive feature of the culture is that lagenaria is one of the ancient plants that were cultivated by mankind as functional and decorative purposes. We have analyzed lagenaria using on the territory of our country. Total analysis with iconic images of plants allowed us to evaluate new opportunities in the use of
culture. In the work we have applied methods of analysis, synthesis and descriptive method
Complicated compost is used for recultivation of soils and represents a new direction in practical husbandry and ecology defining the artificial creation of complex mixtures of different wastes of industrial and agricul-tural production, as well as household residues and natural materials for the enrichment of organic and mineral dispersed and colloidal systems with purpose to improving their physical, chemical, biological and ecological functions
The number of microarthropods in the black soil de-creased with an increase in the number of oil. The same pattern was observed until a certain concentra-tion of lead in soil (von 250 mg / kg), after which high doses (500 and 1000 mg / kg) was recorded an in-crease in the number of microarthropods. Gamasid mites and ticks of akaroid-trombidiform complex have proven more resistant to lead, and armored mites and springtails - to oil, vise versa
In cell biology, actinomycin D is shown to have the ability to inhibit transcription. Actinomycin D does this by binding DNA at the transcription initiation complex and preventing elongation of RNA chain by RNA polymerase. When soaking the seeds in a solution of actinomycin D, antibiotic blocks RNA synthesis and seed germination occurs at the expense of long-living RNA, available in the mature seed. In the article we present experimental data indicating that as storage seeds of winter barley are changing the action actinomycin D on the growth of coleoptiles. It is shown that actinomycin D at a concentration of 40 µg/ml in October reduced the growth, in December it was not authentically, and in February it was paradoxical amplified growing coleoptiles. We suggest the part of the actinomycin D fastened with growth inhibitor coleoptiles, whose structure changes during seed storage and increase the affinity of actinomicyn D to the inhibitors. At a concentration of 60 µg/ml actinomycin D effectively reduced of the coleoptiles growth. Suppression of seedlings roots growth was proportional to the concentration of the actinomycin D and exposure time
We know, that in the development of the natural ecosystems of the Western Priazovye its biomass predominates. This ensures the maximum protection from noticeable changes of habitat. Basic succession defining a significant shift of energy flow in the direction to increase of their expenditures to maintain forming populations determined by broad specialization of natural systems on ecological niches, and their individuals have rather small size, the life cycles of many of them are very simple and short. The coastal strip of the Azov Sea has been seriously degraded due to powerful recreational load, especially in the summer. Presumably one should expect an increased anthropogenic load on ecosystems of this area. Quite obvious is a regularity of overload agroecosystem which occupies the territory between the river and other water formations. The relatively low productivity of agricultural systems of the Eastern Azov is limited by number of factors, among which the main place is occupied with the moisture, nutrients and high weediness of sown areas
The article cites the results of our studies of species composition of moths and their trophic communication as well as alternative types of plants used by owlet moths on the Nordovy island. Also, the article presents the species composition of fauna found on the island
We have assessed the effect of the new generations of fungicides on the vital activity of daphnia. The data of the chronic experiment allowed us to determine non-effective and threshold concentrations of the substances studied. The toxic effect of the xenobiotics is shown to be of different intensity. When entering water they may be dangerous, first of all, for the zooplankton that is the food base of young fish, and may have unfavorable effects on fish development
In the article we have conducted the estimation of
breeding population of salix acutifolia. We have
studied the following indicators of the measured trees:
the percentage of salicylates, bark content in relation to
the wood. For these two indices we have calculated the
"complex" productivity of the trees. Based on that, the
trees are assigned to these breeding categories:
Category 1: trees with high productivity - ( 49.7 - 39.9
kg / t of raw materials) Category 2 : trees with average
productivity - ( 39.1 - 33.8 kg / m raw materials)
category 3 : trees with low productivity - ( 31.8 - 24.3
kg / t of raw materials)
It this article, the situation in dairy practice with nutrition factors caused metabolic diseases such as ketosis, acidosis, lameness and a decline in fertility is shown. The article has the proposes on the nutrition of highly productive cows in transition period
