The article provides information about phytochemical
investigation, medical and nutritional importance of
fruits of Capparisherbacea L. including
CapparaceaeJuss. family in the area of the Nakhchıvan
Autonomous Republic. Some solvents had been applied,
fruit and leave extracts had been bought. The
purification and identification of content of plant
extracts had been investigated with spectroscopic and
chromotographic methods. The saponins, carotinoids,
chlorophyll pigments and flavonoids had been revealed
in the content of extracts. The extracts have been
acquired from fruits of this species by use of polar and
nonpolar solvents and the composition of extracts have
been studied with different applied methods. The
column and thin layer chromatography carried out in
order to purification of contents and extracts were
fractionation and Rf values were calculated
In the present study, fauna of small mammals of the
Taman Peninsula is analyzed. It is shown that the
complex of rodents and insectivores inhabiting the
study area differs considerably from the adjacent
continental areas and is an isolate. Structure of its
fauna and population resembles that of the steppe parts
of Crimea and, at the same time, North-West NearCaspian
areas. Analyses of variation of the D-loop
regions of mtDNA in yellow-bellied mouse Sylvaemus
witherbyi, as well as certain peculiarities of the species
diversity, show the priority of faunal and genetic
connections of the Taman Peninsula’s mammal fauna
with the North-West Near-Caspian one
The pathogenic agent of apple scab disease, Venturia
inaequalis (Cooke) Winter, causes significant damage
to the industrial production of apples. Studying the
pathogen in pure culture is important for solving the
theoretical and practical issues of its biology. The
sporulation ability of the Venturia inaequalis
laboratory culture is an important diagnostic feature in
morphological culture analysis, in the test for
sensitivity to fungicides, when creating a collection
inoculum for an artificial infection. We have studied
the morphological features of conidiogenesis of pure
V. inaequalis culture, such as the location of
conidiogenic structures and their form. For the first
time in the laboratory culture of the pathogen,
sporulation in the thickness of agar on the substrate
mycelium was demonstrated. Conidiogenesis
proceeded according to the blastic-annellidic type.
Depending on the location of the conidiogenic
structures on the aerial or substrate mycelium, their
morphology was different. Conidiogenic areas in the
substrate mycelium could be observed with the
unaided eye, in the form of hyphal grit, while they
were conidia conglomerations in each annelid.
Annellide had a curved shape. On the aerial mycelium,
annelids were straight and always had only one
conidium. Differences in the morphology of
conidiogenic structures are supposed to be related to
the physical conditions of the environment in which
sporulation takes place. In the agar, each mature
conidium remaining at the apex of the annelid
interferes with the formation of the next one, which
results in its bending. The fixed arrangement of
conidiogenic structures and forming conidia in the
thickness of agar allows the use of substrate
sporification for model studies of the conidiogenesis
process
The article presents the results of the studies on the
variability of morphological traits of the
cenopopulations of Allium prostratum, Allium
ramosum on the natural territory of the Yakutsk
Botanical Garden and in cultura. We have performed
researches of biometric parameters, which revealed the
structural features of the plant and the nature of the
variability of their parts. The article also gives an
estimation of coenopopulations vitality
The article presents the results of the genetic analysis of the trait ‘plant height’ for six crosses involving the forms related to different subspecies of rice. There have been estimated the types of inheritance and a number of genes, which assist to determine this quantitative trait. We have found out that the variance of the trait ‘plant height’ is determined by 3-5 pairs of genes having additive and dominant activities and the degree of dominance reduces in case the variance among parental forms increases. The non-allelic interaction of the genes of the initial forms produces transgressive dwarf and tall forms. The cross ‘Lampo’x’Virazh’ showed the highest degree of transgression in ‘plant height’ due to short height of both parental forms (61.7%), but the frequency of transgression was larger than that of the cross ‘Lampo’x’Komandor’(17.6%). This combination (‘Lampo’x’Komandor’) produced more tall forms (up to 135 cm). The segregation of a great number of tall forms into F2 testifies that the parental forms of these hybrids vary in the allelic state of several pairs of genes, whose various combinations form phenotypes with a longer stem. Thus, the semi-dwarf feature of the varieties ‘Lampo’, ‘Komandor’ and ‘Virazh’ is determined by various non-allelic genes
Clonal micro-multiplication – is this the basic method
of obtaining the qualitative virus-free planting
material. The high quality specificity of the explants
reaction of the grapes varieties to the composition of
nutrient medium requires the individual selection of
the medium components for the most successful multiplication
in vitro. In the article we present the results
of studies on the cultivation of the grapes apexes
in vitro the modified medium with the reduced
content of macrocells. As a result of conducted investigations
we have established that for the grapes varieties
of Academic Trubilin, Artemis, Gurman
Kraynova, Maria Kallas, Nizina, Petit Verdo and
Traminer Black the most effective introduction into
the in vitro culture (acclimatization of apexes 80-
100%) occurs on modified nutrient medium to
Murasige and Skoog (1962), by being differed in
terms of the content macro-elements (mG/l):
NH4NO3 – 1237; KNO3 – 1425; MgSO4 ·
7N2O – 277,5; KN2PO4 · H2O – 277,5, of the
vitamin Of v1 – 10,0 mG/l, nicotinic acid – 4 mG/l.
Remaining varieties of Kishmish luchistiy, Preobrajenie,

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 results of scientific investigations in specifying
environmental and faunal composition of soil
invertebrates at agricultural landscapes of steppe zone
of the Krasnodar region are presented this article.
Observed territory is represented with four main
classes of animals: Insecta (insects), Crustacea
(cancroid), Myriapoda (myriapod), Olygochaeta
(worms with small bristles). Those animals were the
subject of further descriptions of territory. Some
peculiarities and regularities of quantity and taxonomic
compound of mesofauna, depending on technological
methods that are being used for cultivation of
agricultural crops in experimental farming JSC
“Zavety Il’icha” of the Leningrad district, are
considered. The observed area is mostly populated
with soil inhabitants (68,7%) that include such families
as Geophilomorpha (geofila), Lithobiomorpha
(drupes), Julidae (millipede), Enchytraeidae,
Lumbricidae (earth worms). It was found that the use
of complex compost (as an alternate method of
cultivating the winter wheat and the sugar beet) has a
positive impact on a biological activity of ordinary
chernozem. The introduction of complex compost
optimized the ecological state of agrolandscape
system, which is associated with activation of biophilic
elements at upper soil layer. An upgrade of soil
structure, water-holding capacity and agrochemical
properties creates enabling environment for the vital
activity of invertebrates and for their trophic
cooperation with the habitats
Researches on non-root additional fertilizing of grapes with complex water-soluble fertilizer called Nutrivant plus have been conducted in corporation "Pobeda" in Temrjuksky area of Krasnodar territory on the implanted plantings of technical grade Rhine Riesling. In the test, the following kinds of Nutrivant plus were used: oleiferous (N0P20K33), sugar beet (N0P36K24), grapes (N0P40K25), universal (N19P19K19), grain (N6P23K35). Each mark of Nutrivant plus contained a certain set of microelements. The test consisted of six variants:1 variant - without additional fertilizing(control); 2 variant: grapes - before flowering, grapes - a growth phase of berries (a berry about a pea), oleiferous - the beginning of maturing of berries; 3 variant: universal - before flowering, universal - a growth phase of berries (a berry about a pea), oleiferous- the beginning of maturing of berries; 4 variant: grain - before flowering, grain - a growth phase of berries (a berry about a pea), oleiferous- the beginning of maturing of berries; 5 variant: Sugar beet - before flowering, a sugar beet - a growth phase of berries (a berry about a pea), a sugar beet - the beginning of maturing of berries; 6 variant: universal - before flowering, grain - a growth phase of berries (a berry about a pea), grapes - the beginning of maturing of berries. Norm of the expense of fertilizer is 3 kg/hectares. The expense of a working liquid - 700 l/hectares. The result was, that in the third, fourth and fifth variant of the test the increase in a crop from a bush happened accordingly on 7,5, 13,8 and 17,8 %. The maximum increase of a crop in the fifth variant was accompanied by increase in mass concentration of sugars in juice of berries on 0,6 g/100 см3и decrease titratable acidities for 0,6/dm3 As a result triple not root additional fertilizing of grapes plants grade Riesling with Nutrivant plus (universal - before flowering, grain - in a growth phase of berries and grape - in the beginning of maturing of berries) promoted more optimization of a water mode of leaves, increase in weight of a cluster, a crop from a bush and productivity, mass concentration of sugars and phenolic substances in juice of berries
