This article discusses the use of nuclear magnetic resonance spectroscopy for the determination of biologically active substances-producing plants in the culture of in vitro and in situ. The same is said about the benefits of obtaining biologically active substances from plants in culture in vitro. Formulated a number of problems for theoretical study and experimental development basic principles on the use of nuclear magnetic resonance spectroscopy in pharmaceutical analysis for standardization and quality assessment of BAS
In order to identify high-genotypes in natural stands of
Sacutifolia Willd we worked to identify the categories of breeding trees. Experimentally proved, that for breeding to increase the productivity of bark of Salixacutifolia Willd the selection would be best carried out with plants, the diameter of the barrel of which is in the range of 9 to 16 cm, tree age 15 - 19 years
In the article we have investigated the ontogeny and
the peculiarities of the passage of its stages from
Pulsatilla patens (L.) Mill. We have characterized the
morphological features of the developmental stages.
The age structure of populations and the influence of
anthropogenic factors on it have been set
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)
Distribution peculiarities of planted Pine and Fir species (I and II age classes) in different sites of Mari high plains in accordance with their relative density and share of participation of target tree-species are described in this article. Based on the obtained
data, some actions for enhancement of ecological and
resource potential of the species are elaborated
This article includes the value of forage and species composition of legume forage plants of summer pastures in Nakhchivan region. We have found that the forest, subalpine and alpine meadows and covers are regularly arranged in the vertical zone. We have also learned the species content. Flora of summer pasture forage plants rich in resources which have 1588
species (56% of the flora of Nakhchivan region)
In the present article the authors provide an overview
of the results of experimental works for the use of electro activated water solutions in agroindustrial complex
In this article we present data on the effect of addition
of mineral nutrition elements in the structure of the
phytoplankton community in the north-eastern part of
the Black Sea in the different seasons. Experimental
studies have shown that the increase in biomass of
microalgae occurs at the simultaneous addition of
nitrogen and phosphorus in the accumulative cultures.
In the spring can get biomass Emiliania huxleyi,
P.pseudodelicatissima, Chaetoceros curvisetus and
Skeletonema costatum, in the summer – E. huxleyi, C.
curvisetus, P.pseudodelicatissima, S.costatum,
Thalassionema nitzschioides, Leptocylindrus danicus,
Dactyliosolen fragilissimus, Proboscia alata,
Pseudosolenia calcar-avis, in the autumn - C.
curvisetus, S.costatum, Th. nitzschioides, L. danicus,
D. fragilissimus
The purpose of the article is an examination of plus trees clones based on growth study in the seed orchard. The studied clones differ with the characteristics of growth. The perspective clones were selected by using an integrated examination
The article describes the environmental conditions and plant communities with Iris laevigata for the selection of optimal locations of its growth. The structure of natural populations can be a model for the creation of artificial populations of these species
