Researches of phenolic compounds Coluria geoides (Pall.) Ledeb. by methods PC, TLC and HPLC chromatographies.
Contents of 15 compounds of the phenolic nature which are presented of fl avonoids, coumarins and phenolcarbolic
acids was established. Th e gallic, protocatechuic and ellagic acids, coumarin, aglycons quercetin, kaempferol, glycosides
of quercetin and kaempferol was identifi ed. Phenolic compounds in this plant are identifi ed for the fi rst time.
The variability of the morphological features of plants Astragalus austrosibiricus (Fabaceae) at diff erent heights above
sea level in diff erent years of observations was studied. Th e range of morphological variability in diff erent ecological
and geographical conditions was shown. Th e complex of traits was revealed, which are characterized by high correlation
coeffi cients and by set the degree of infl uence factors on the variability of some studied morphological attributes.
By method of X-ray fl yuorescencent analysis using of synchrotron radiation (RFA SI) Content of 19 chemical elements
in vegetative and generative organs Lathyrus vernus (L.) Bernh. and in soils, which he sprouts was studied. Th e
change of element composition during a vegetation period is shown. Th e coeffi cients of biological accumulation of
microelements (KBN) showing the degree of their concentration.
Th e objective of the research described in this paper was to evaluate genetic diversity of endemic species Hedysarum
theinum Krasnob. by inter-simple sequence repeats (ISSR) analysis of genomic DNA. Th ree ISSR markers were used
to analyze the genetic structure of two H. theinum populations from Altai Republic, Russia. Revealed high DNA
polymorphism allows using ISSR technique as a powerful and effi cient approach for research an interpopulation
diversity and genotype fi ngerprinting.
Th e method of studying of characteristics of the latent period for the species of the genus Viola was developed. Th e
seed production, ground and laboratory germination, conditions for seed germination and dynamics of its
germination were defi ned for species of section Mirabiles (V. mirabilis and V. subglabra). Th e dependence of the
germination, the energy of germination and the intensity of energy of germination were identifi ed. Th e duration of
preservation of seed viability were found.
Comparative analysis of leave series for two similar species of genus Euphorbia section Esula: Euphorbia borealis and
E. microcarpa is performed. New leaves parameters for the more accurate diagnostics of these species are revealed
and described: width and shape of lower leaves, width and shape of meddle leaves, form of the bract base, and some
others.
Th e infl uence of the air temperature, relative humidity and rainfall on the expression of sex polymorphism in plants
Th ymus elegans Serg. was investigated in the forest-steppe of Novosibirsk Oblast.

Th e results of primary studying of 21 onion species in conditions of a forest-steppe zone of the Altai Territory are
presented. Peculiarities of a seasonal development of species with the account of temperature factor are discussed. It
is proved, that all the species, with the exception of A. moly, are developed normally, A. neapolitanum has low winter
resistance in severe winters. Seeds quality is high. 7 species are recommended for ornamental horticulture.
Isolation of species Elymus pendulinus, E. brachypodioides and E. vernicosus is prejudiced by results of analyses of
herbaria and a live material in connection with their eсological and geographical specifi city. On the basis of the revealed
variation of the basic diagnostic characters the conclusion has been drawn that splitting of the complex E. pendulinus
s.l. on independent species is not to be proved.
Th e fl ora of steppes of the Baikal Siberia (BS) is rich enough (666 species of high vascular plants), that is a consequence
of features of a climate, orography, and also its buff er position between Northern and the Central Asia. In a variety of
steppe relicts BS are in some measure refl ected palaeogeographic events in open spaces of Northern Asia throughout
last 3-5 million years, from tertiary savannas and deserts to tundra-steppe landscapes of Pleistocene. Besides in an
exchange and transformation of fl ora the great value had as median position of territory BS in a trans-Asiatic
mountain belt, and climatic influence of Megaberingia, and also influence of glacial epoch, connected with
cryoaridisation. All it has formed a basis of high uniqueness of fl ora of steppes BS. It not only the most ancient relicts
of paleogen-neogen age (Peganum nigellastrum, Caryopteris mongolica, Craniospermum subvillosum), but also
pleistocene periglacial (Chamaerhodos altaica, Oxytropis eriocarpa, Patrinia sibirica, Gentiana decumbens, Artemisia
depauperata). Its perfect model for knowledge fl orogenesis not only in mountains of Siberia, but also the north of the
Central Asia.
