Biological Institute of Tomsk State University, Tomsk, Russia.Towards the study of subsection Malacanthae (Roshev.) Probat., genus Poa L.(Poaceae). In Eurasia subsection Malacanthae (Roshev.) Probat. (Poa L.) is representedby 25 species. Three contemporary centers of diversity can be recognized there:European, Central-Asian and Pacifica. The last one is most rich in species and representedby 12 ones. Some species of that center - P. arctica, P. lanata, P. macrocalyxTrautv. et Mey. - are supposed to have passed to N. America via Beringia. For resolvingthe problems of phylogeny and phylogeography of subsection Malacanthae thesearch on molecular level should be undertaken.Key words: grasses; Poa L.; Siberia; biodiversity; biogeography.Rybina Tatiana A., Amelchenko Valentina P., Manassypov Rinat M. Siberian botanicalgarden of Tomsk State University, Tomsk, Russia. Modern condition of floraand populations of rare kinds of plants in especially protected natural territory«The forest park in area of the Academgorodok» in Tomsk. The modern conditionof flora of a forest park in Akademgorodok is considered. Botanical analyses, the list ofrare plants and perspective for inclusion in the Red book are given. The map of modernvegetation with accommodation of rare plants, the characteristic of its habitats andconditions of populations, a degree of anthropogenous transformation of flora, and therecommendation on protection of a vegetative cover are given. Work has a historicalvalue as since 2008 in territory of a forest park began active development of an infrastructure,that, undoubtedly, will lead to strong change of a floristic situation.Key words: especially protected natural territory; map of vegetation; anthropogenoustransformation; the Red book.BIOTECHNOLOGYDorofeev Vyacheslav Yu., Karnachuk Raisa A., Pulkina Svetlana V., KomlevaEkaterina V., Dubina Valentina B., Medvedeva Julia V.

Atragene speciosa Weinm. culture in vitro:the cytogenetic analysis and formation of triterpenoid glycosides and flavonoids.Atragene speciosa Weinm. can be used as nootropic, adaptogenic, etc. remedy fortreatment of some diseases. Biological features of this species do not allow its cultivation.Atragene speciosa cell culture in vitro has been received. Formation of physiologicallyactive substances, including flavonoides and triterpenoid saponins was discoveredin the cells callus culture in vitro. Genetic instability of callus culture and severalcytotypes on chromosomes number and aberration structure are found.Key words: Atragene speciosa Weinm.; cell culture; in vitro; triterpenoid glycosides(saponins); flavonoids; polyploides; aneuploides; chromosomes structure.MICROBIOLOGYTereshchenko Natalie N., Bubina Alla B. Department of Agricultural Biotechnology,Biological Institute of Tomsk State University; Laboratory of Microbiology, SiberianResearch Institute of Agriculture and Peat of SB RАS, Tomsk, Russia. Microbiologicalcriteria of soil ecological stability and efficiency of soil-protecting technologies.The comparative researches of microbiological properties of sod-podzoliclight loamy soil, within 8 years taking place under influence of cultivation systems ensuringopposite strategy of soils ecological transformation (from the degradation to thehumus accumulation) have allowed to reveal a number of significant microbiologicalcriteria of ecological soil stability and efficiency of soil-protecting technologies: Simpson'sindex of a variety of microbial community, designed both for rhyzosphere, andfor nearby rhyzosphere area; a mycotrophic degree of plant roots; frequency of mycorhizaoccurrence; parity of average levels of Pseudomonas growth stimulating activityin rhyzosphere and in nearby rhyzosphere area.Keywords: microbiological criteria; soil ecological stability; soil fertility; field vermicultivation;soil cultivation systems; a biodiversity.SOIL SCIENCE AND FORESTRYBender Olga G., Zotikova Albina P., Velisevich Svetlana N. Institute for monitoringof climatic and ecological systems SB RАS, Tomsk, Russia. Water relation featuresand pigment complex state of Pinus sibirica Du Tour needles in the North-Eastern Altai mountains. Morphology and anatomy, water relation specific featuresand pigment complex states of Pinus sibirica Du Tour needles at North-Eastern Altaimountains were studied. The needle length decreases across altitudinal transect, but theareas of resin canals, central cylinder and mesophyll on cross section increases. Thenumber of stomata per leaf volume unchanges with increasing elevation. Ratio ofbound water to free water changes across altitudinal transect, water contents decreasesand water deficit increases. Maximum transpiration is observed at the lowest and thehighest sites of transect and is influenced by both soil and climatic conditions. Chlorophylla and b contents decrease with up gradient, but chlorophyll a is affected to agreater extent than chlorophyll b. The both carotinoid contents and ratio of chlorophyll(a+b) to carotinoids increase at the highest sites.Key words: Pinus sibirica; altitude; water relations; photosynthetic pigments; needlestructure.Annotations 111Velisevich Svetlana N., Khutornoy Oleg V., Chitorkina Ol'ga Y. Institute formonitoring of climatic and ecological systems SB RАS, Tomsk, Russia. Growth andreproduction of Pinus sibirica Du Tour subpopulation on altitudinal transect inthe North-Eastern Altai. The vegetative and generative morphogenesis of Pinus sibiricaDu Tour subpopulation on altitudinal transect was investigated. It was determinedthat the value of growth traits and quantitative traits of generative developmentthat characterize the micro- and macrostrobiles production decreased gradually alongaltitudinal transect. The maximal value of qualitative traits that indicates seeds viabilityand potential possibilities to forest reproduction had subpopulation on mountain taigaand subalpine zone.Key words: Pinus sibirica; growth; reproduction.Zakharikhina Lalita V. Geotechnological Scientific Research Center of the FEBRAS, Petropavlovsk-Kamchatsky, Russia. Distinctive features of soil formation in theconditions of active volcanisms (by the example of Kamchatka). It was shown thatvarious conditions of soil formation were typical for young basaltic volcanism and itsmature calderaforming stage. The above stages differ in scales, eruptions frequency andcomposition of their material which are the cause of differences in soils construction,intensity of illuvial processes in the soils, humus content, pH reaction of organogenichorizons, degree of soils saturation with bases.Key words: volcanism stages; eruptions frequency; soil formation.Kulizhskiy Sergey P., Blohin Aleksandr N.

Physicomechanicalproperties of soils on the example of the humus-accumulative soil horizonssouth of Siberia. The text of the article highlights the state of steppe soils of therepublic of Khakassia in the position of their resistance to mechanical stress.

Geochemical differentiation of soils ofthe hollow of lake Shira. Results of researches of element structure of a soil cover andsoils of Shirinsky island steppe on an example of modelling object - lake Shira depressionsare discussed. Geochemical specificity of soils and factors, its defining is considered.The basic properties of the components composing soil combinations are studied.The variation of size of local geochemical norm in space that testifies to non-uniformdistribution of elements within natural object - a lake hollow is revealed.Key words: Shirinsky island steppe; lake Shira; geochemical specificity of soils;lake hollow.
