EVALUATION OF SELECTION OF TREES OF SALIX ACUTIFOLIA WILLD
DescriptionIn 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

PECULIARITIES OF ONTOGENESIS AND POPULATION AGE STRUCTURE OF PULSATILLA PATENS (L.) MILL
DescriptionIn 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

Description
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)

BROAD BEANS LEGUMES OF SUMMER PASTURES OF THE NAKHCHIVAN AUTONOMOUS OF REPUBLIC OF AZERBAIJAN
DescriptionThis 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)

GROWING DOMINANT SPECIES OF MICROALGAE IN NORTH EASTERN BLACK SEA
DescriptionIn 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

BIOTECHNOLOGY OF TRICHODERMA-BASED FEED ADDITIVE WITH CELLULOLYTIC PROPERTIES
DescriptionIn the work, we have presented the information of elaboration of a manufacturing process of Mycocel feed additive with the cellulolytic activity for poul-try industry. Manufacturing process includes follow-ing steps: stock culture maintenance and storage of Trichoderma lignorum 81-17, growing fluid culture of microscopic fungus in sucrose yeast extract me-dium, feed additive with cellulolytic properties out-put and quality control, packaging, storage and disposal of waste. We have shown that the Mycocel is non-toxic feed additive for protozoa and warm-blooded animals (laboratory mice and quails). This study demonstrated total population livability in the experimental group with feed additive. Quail body-weight of experimental group was higher by 6% as compared to the control and feed consumption per 1 kg of live weight of bird was 3,58 kg, 7,5% lower than the control
