In the article we present data of researches on bio productivity of forest plantations on sand-shell rock soils
The article gives an analysis of the elemental
composition in raw materials of stevia. Stevia plant is
able to regulate the flow of heavy metals, allowing
them, on the one hand, actively oppose the excessive
intake of toxic elements and on the other hand,
selectively cumulate essential elements. The contents
of essential elements in plant raw materials do not
exceed the acceptable standards regardless of the
growing conditions
The article provides information about the species
diversity of the family of Asteraceae in the natural area
of the Yakut botanical garden. We provide the
information about the method and the area of the
study, the description of the phytocenotic surrounding,
taxonomic analysis, areal analysis, bio-morphological
analysis (the variety of life forms) which was given by
the K. Raunkier, rhythmological analysis,
environmental analysis (by A.P. Schennikov),
analysis of phytocoenotic
Results of testing of multiplex sets SSR-markers for
genotyping of rice varieties are presented in the article.
Two sets of SSR-markers were formed:
1: RM1+ RM11+ RM70+RM122;
2: RM164+RM167+RM168.
The optimal combination of DNA markers in the
multiplex sets and PCR conditions allowed obtaining
accurate, easily interpretable results when performing
fragment analysis on automated genetic analyzer
ABIprism3130. Using multiplex sets, genotyping was
performed for several varieties of rice: domestic
breeding and one variety – IR36 from the breeding of
IRRI (Manila, Philippines). For all the studied
varieties specific SSR-fingerprints were obtained.
RM 168 marker showed in domestic varieties a low
level of polymorphism - one allele of 97 bp. However,
at the same time, the variety IR-36, showed a second
type of allele 107 bp. In addition, the loci of RM1,
RM11, RM167 and RM164 have unique alleles in this
variety. It is consistent with significant genetic
differences of these varieties and the rest of the
varieties in studied sample. The proposed SSR
multiplexes are promising for use in DNA certification
of rice varieties and assessment of genetic diversity
The article discusses the features of the accumulation of essential oil in the collection samples of Oregano studied in the foothill zone of the Crimea. The range of variability of the mass fraction of essential oil of Origanum vulgare (from trace amounts to 0.53% of the bone dry weight). We have revealed that the greatest
amount of essential oil accumulates in the inflorescences during the flowering phase
Soil degradation (erodere – eat away, lat.) - a process in which result pieces of rocks and soil are separated from of their initial location. Is then transferred and deposited in some new place. The factors of erosion are water, wind, landslides, rock particles and etc. Erosion is the process of destruction and demolition of the soil cover (or parent rocks) flows of water or wind what causes depletion of fertile top soil layer. The destruction of this layer occurs quickly, and for its restoration required the millennium. Reduction of soil fertility is one of the main problems that are associated with its pollution. Erosion is a natural process that occurs very slowly ever since as the Earth was formed (about 45-50 billion years ago). Realistically, mountains, valleys, plains and deltas on Earth's surface have been created by water and wind erosion as a result of their joint action over a long period of time. Geological erosion was acted at a slow pace for hundreds of years. With the emergence of the human occurred of invasion species which could transform their natural environment. Artificial type of erosion, which acts much faster than the natural erosion, was formed with the appearance human
The researches are devoted to the determination of physiological parameters of grafted apple-trees joining with the level of their resistance to the change of soil рН. The experiments were carried out in the conditions of lysimetric experience with the soils use characterizing by different value of рН. The scheme of experience included the following variants of soil medium reaction: neutral (рН 7,3), typical for black soils of plain part of the region (control); weak-acid (рН 6,2) existing in soils of foothill zone of the region (grey and brown forest); strong-acid (5.1) typical for brown forest soils; weak-alkaline(рН 8.3) occurring in black soils of south and sod-carbonate soils, strong-alkaline ( рН 8.8) typical for maternal types of many black soils. There were studied the varieties of apple-trees Prima, Florina and Renet Simirenko grafted on stocks M9 and MM106 and as well as corresponding the non-grafted stocks. The reaction of grafted apple-trees on change of рН of soil is specific and depends on adaptive possibilities of grafting components: varieties and stocks. At the stock M9 we can see the active growth of shoots and roots in the meaning of pH values from 5,1 (strong-acid reaction) to 7,3 (neutral). Plants MM106 prefer neutral (pH 7,3) and weak-alkaline (pH 8,3) soils. Independently from stocks for the variety Florina the most favorable weak-acid soils and the variety Prima – mainly neutral. The variety Renet Simirenko possesses enough high and stable functional activity in the conditions of wide range of the medium reaction: from very acid to alkaline one
Sunflower is one of the most important oilseed
crops, which are of great economic importance in
Russia and in the world. It is very adaptive crop
in terms of climatic conditions range, for that
reason it is cultivated on a vast territory of the
Russian Federation in various weather conditions.
Sunflower oil has high nutritional and taste
qualities, it is used numerously in food and is
applied in various fields of food industry. The
biologically active linoleic acid, phosphatides and
fat-soluble vitamins A, D, E and K, which are of
great nutritional value to humans, are contained in
the oil. According to its calorific capacity,
sunflower oil is on the first place among
vegetable oils. Due to biological characteristics of
sunflower, the Krasnodar region is the most
favorable region of the Russian Federation for
obtaining high and stable yields of this crop.
However, here the drought is observed during the
summer period and it affects adversely the
productivity and quality of sunflower seeds. The
increasing of resistance to unfavorable weather conditions is possible only based on detailed
study of physiological features of productivity
formation and seeds quality that is highly
important task in view of the current geopolitical
situation in Russia. One way of solving this issue
is the appliance of the growth regulators,
possessing anti-stress activity that improve the
quality of sowing seeds and increase the
productivity and plant resistance to stressful
environmental factors. These drugs include
growth regulator called Furolan, which was
created in KubGTU and is certified for use in
Russia. It is not toxic and is used in nano-dozes,
there is no its residual quantities in the products
and environment. Furolan has a positive effect on
physiological and biochemical processes,
improves the productivity of plants, their
resistance to unfavorable growing conditions by
increasing the resistance to dehydration as well as
to the risk of fungal diseases
