Peculiarities of pollen formation and morphological parameters of pollen grains in 4 Picea A. Dietr. species from
collection of Institute of Forest SB RAS Arboretum (Krasnoyarsk) were determined. High pollen quality of ornamental
form of local species P. obovata and introduced species P. ajanensis and P. mariana has been shown. Decreased
viability (71.6 %) and high frequency of abnormal grains (14.1 %) were character for P. pungens pollen.
Th e data about a genetic variability, structure and degree of diff erentiation populations of Siberian larch, Gmelin larch
and Cajanderi larch were obtained. It was established that studied species are diff ered in genetic structure, and the
most signifi cant diff erences are observed between populations of Siberian larch and group of populations of Gmelin
larch and of Cajanderi larch.
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.
