Distribution of viable seeds on the bare ground slope in a sand quarry located in the vicinity of Saint-Petersburg was studied in relation to the relief of the ground surface, species composition of pioneer communities and surrounding vegetation, as well as the timing of a growing season. Seeds were found even on bare ground and poorly vegetated sites. Ground contains three times more seeds in autumn than in early summer. Most of seeds belonged to perennial grasses (mainly anemochorous, apophytes, and weeds), with a few coming from other life-forms (from annuals to trees), which were spread in the quarry or in the surrounding vegetation. Seeds concentrated on the slope, their number was the lowest in the quarry bottom in both observation periods, since conditions favored to plant germination there. The microrelief of the ground surface can also influence seed distribution: in June, viable seeds mostly located in depressions. We suppose that in dissemination period, seeds of anemochorous plants concentrate on hillocks which trap them; however, more data is needed to conclusively prove this hypothesis. The paper contains 3 Tables, 3 Figures and 49 References.

We studied the effect of soft wheat seed treatment (Triticum aestivum L.) with two bacterial strains (Aeromonas media GS4 and Pseudomonas extremorientalis PhS1) isolated from earthworm coprolites on the growth and development of wheat seedlings in a 12-day laboratory experiment, as well as on root rot disease and the activity of guaiacoldependant peroxidase under optimal conditions and abiotic stress (elevated and low temperatures and moisture content). We established that growing nonbacterized wheat plants under stress abiotic conditions reduced the height of plants compared to growing under optimal abiotic conditions, and seed bacterization with P. extremorientalis PhS1 strain increased wheat plant height (by 9-15%) under stress abiotic conditions compared to the nonbacterized plants. Bacterization with both strains decreased infestation of wheat seedlings (2.5-4 times) by root rots under unfavorable abiotic conditions compared to nonbacterized plants. In addition, under optimal and arid conditions, bacterization with P. extremorientalis PhS1 strain was the most effective, and under humid conditions it was bacterization with A. media GS4 strain. We showed that the activity of guaiacoldependant peroxidase correlates with the development of plant resistance to abiotic stress. In our experiments, plant bacterization resulted in a 2-fold increase in peroxidase activity both in leaves and roots of wheat plants compared to the nonbacterized plants. As the result, the ability of bacteria to activate peroxidase can serve as an information indicator of strengthening protective mechanisms of plants during bacterization. The paper contains 4 Figures and 34 References.

The life form and the ontogenesis of the perspective medicinal plant Saussurea controversa DC. (Asteraceae) are described. The species is considered as polycentric, perennial, summer-green, herbaceous polycarpic half-rosette plant with rhizome. The aerial part of the plant includes the polycyclic rosette vegetative and elongated generative shoots. In the ontogenesis, four periods and nine ontogenetic states are distinguished. The ontogenetic and vital structures of four populations were studied in the vicinity of Efremkino village (Republic of Khakassia). Populations are incomplete with accumulation of virginal individuals and predominance of individuals of intermediate and high classes of vitality. Analysis of the distribution and resource research in the population with the highest density and area makes it possible to classify the species as the 3rd category of resource species due the necessity to observe the regime of sustainable use. The diagnostic features of the S. controversa’s raw material are the structure of the middle vein of the leaf which includes a large number of vascularfbrous beams and the abaxial epidermis containing stomata of the anomocytous type and 4 types of trichomes. The paper contains 3 Figures and 27 References.
