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)

TEXTURE OF YOUNG PLANTED FOREST (PINE AND FIR SPECIES) IN MARI HIGH PLAINS AND ITS OPTIMIZATION
DescriptionDistribution 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

USE OF NONTRADITIONAL FERTILIZERS IN CULTIVATION OF PLANTED SCOTCH PINES ON THE RECULTIVATED GROUNDS
06.00.00 Agricultural sciences
DescriptionThe results of use of nontraditional organic fertilizers on the basis of wastewater sludges and sawdust in sand pits earth stabilization are considered. It was ascertained that a dose of introduced fertilizers has higher influence on hydrophysical and agrochemical properties of soils than shelf life of the fertilizers. A tendency of enhancing growth of intended purpose planted pines on the back of improvement of physical and chemical and biological properties of sandy soils, enrichment of species composition with grassland vegetation after nontraditional organic fertilizers treatment is revealed

GROWTH AND PRODUCTIVITY OF POPULUS TREMULA L. IN THE KOSTROMA REGION
06.00.00 Agricultural sciences
DescriptionA comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation
