The article presents the seed productivity of five cultivars of Poa pratensis L. for lawn purposes and three wild-growing specimens of Poa pratensis L. and Poa angustifolia L. from natural populations in the south-east of Kazakhstan and in the south-west of Siberia, summarized over three years. The onset of the main phenological phases was determined, taking into account the weather conditions of the region where the experiment was held, and a comparative analysis between the samples was carried out. The correlation connection between three signs of the reproductive sphere and their consistency with weather conditions was researched. For all varieties, a significant conjunction was revealed between the number and weight of seeds per spike, a considerable variation in the coefficient of seed production over the years. The best indicators of seed productivity were noted in the plant variety ‘Novosibirskiy’ and wild forms ‘C-2’ and ‘D1-78’ in Western Siberia, in the plant variety ‘Balin’ and wild specimen ‘K-0027’ in Kazakhstan. The influence of environmental conditions on the organogenic process of P. pratensis was revealed. Additional moisture contributes to the manifestation of the potential capability for seed reproduction of the researched samples of P. pratensis.

Geological Interpretation

In the South of Western Siberia oil-perspectivity Jurassic deposits are characterized by multi – and small-scale. The interpretation of earth remote sensing materials in the visible, near and far infrared ranges allowed to evaluate the oil potential of numerous domes and depressions on the basis of combining geodynamically stressed zones and calculating the physical characteristics of the earth's surface (albedo, radiation coefficient, thermal inertia, convective heat flow, daily evaporation of moisture, DEM, weather conditions, etc.), including the procedure of reference classification, where the standards are the nearest oil and gas condensate fields. The forecast boundary of “oil and gas condensate” lands of the South of Western Siberia is displaced to the latitude of u.v. Lebyazhye of the Eastern part of the Kurgan region.

Grape Varieties

Introduced grape varieties were studied in the south of Western Siberia in order to identify the effects of unfavourable factors of the growing season on the ripening of grape shoots. Weather conditions in the south of Western Siberia during the vegetation periods 2012-2017 were characterized by large fluctuations in water and temperature conditions; there were sharp changes not only in different years, but also during one season. Compared with long-term average data, a significant increase of relative air humidity and the amount of precipitation was noted from May to September. In 2016-2017 sharp changes of the amount of precipitation by months were marked (dry June, over-moistened July). The most unfavorable weather conditions for grape crop were the conditions of the growing season of 2013 with excessive rainfall (410.3 mm), very low average monthly air temperatures in May, June, July, September and the sum of active temperatures (2031.7°C). Under the influence of meteorological conditions, the terms of the beginning of the studied phenological phase changed very significantly over the years (30-62 days). Shoots ripening in years with favourable weather conditions (2012, 2015) began from July 14-August 1, with unfavorable (2013, 2017) — September 11-15. In one grape variety, insignificant variability of the degree of the studied character was revealed by years, in two — medium, in eight — high. Shoots ripened better in warmer and less humid 2012 (66.8-94.1 %) and in 2015 (58.4-92.5 %). Varieties with very poor ripening (33.0-46.9 %) Arkady, Kodryanka, Tomaysky are unsuitable for cultivation under production conditions and recommended for cultivation in amateur gardens with additional shelter. Varieties with maximum ripening of shoots on average over the years were selected from the American group White Pearls, Latvian Pink (83.1-84.9 %), Amurian Adel, Vaskovsky Souvenir, Hasan Bousa (65.5-79.3 %).

In the forest-steppe zone of Western Siberia, a comparative study of seed productivity, flowering features, fruit and seed morphology, pollen fertilization ability was conducted for the first time in representatives of the Hosta Tratt genus: H. decorata, H. sieboldiana, H. lancifolia, H. albomarginata, H. crispula, H. kikutii, H. montana, H. rectifolia, H. undulata and varieties Golden Tiara, Night before Christmas, and Stiletto. It is noted that the reproductive potential and fertility of pollen in 9 species and 3 varieties of host have intraspecific and varietal specificity and are associated with seasonal weather conditions. The results of free pollination of the host were studied. It was found that fruit formation within a single generative shoot is heterogeneous, with the exception of the species H. decorata. The coefficient of productivity of species is 16—93%, varieties 12.5—36.4%. Morphometric indicators of length of generative shoots, fruits and seeds are presented. It is shown that the fruit is a freely opening loculicidal tricuspid capsule. Seeds are linear to oval in shape. It was revealed that with high viability of pollen grains (46—82.6%) in H. albomarginata, H. rectifolia, H. sieboldiana, the productivity coefficient is 2—3.8 times lower than in H. decorata. The flowers are characterized by geitonogamy with the phenomenon of peterandre, chasmogamous pollination and flowering in acropetal direction. H. decorata has a high adaptive advantage of seed productivity. The studied species and varieties consistently pass all the phenophases of development and are characterized by vitality. The growing season from spring growth to fruiting in Novosibirsk is 98—112 days. The reproductive capabilities of the host during introduction in the forest-steppe zone of Western Siberia are realized partly due to seed reproduction and are distinguished by species and variability.

Active Substances

Grapes is a highly valuable food product due to the presence in it of a number of biologically active substances, among which vitamins occupy a special place. One of the most important and studied in grapes is vitamin C (ascorbic acid). The ascorbic acid contained in plant tissue participates in redox metabolism, thereby increasing the resistance of plant organisms to infections and low negative temperatures. Studies aimed at determining the concentration of vitamin C in plant material are important both for breeding and for identifying the most sustainable competitive varieties. The purpose of these studies is to study the content of vitamin C in grapes cultivated in the South of Western Siberia. Conducted research with 12 introduced varieties and selected forms growing in the collection of the Research Institute of horticulture of Siberia M.A. Lisavenko, allowed to establish dependence of accumulation of ascorbic acid in berries on weather conditions; to allocate 5 genotypes with high content of vitamin C. It is noted that the ripening period of berries, their color, as well as the direction of use and ecological and geographical origin of varieties and selected forms did not affect the accumulation of vitamin C in the period 2014–2016.

Aim. The study of the phenology and seed productivity of golden root plants in the 2nd‐4th years of life in the Moscow region under the influence of meteorological conditions. Methods. The objects of research were plants of golden root from the biocollection of VILAR in Moscow. The studies included field and laboratory experiments, which conducted in 2016‐2019 according to methods adopted in medicinal plant production. Weather conditions in the Moscow region during the research period were identified on the Internet. Seed productivity was assessed according to generally accepted methods. Determination of seed sowing qualities was carried outaccording to National Standard 34221‐2017.Results. The influence of weather conditions on the passage of phenological phases of young golden root plants in 2016‐2019 in the Non‐chernozem zone of the Russian Federation under experimental field conditions was studied for the first time. The duration of phenological phases depending on conditions in the year of observation was determined. The composition of the population of young golden root plants for the second, third and fourth years of vegetation wasestablished. Adverse factors which reduce seed productivity and affect the quality of seeds were identified.Conclusion. The favourable meteorological characteristics of the growing season contributed to an increase in the mass of 1000 seeds by an average of 43 mg and increased seed germination to 82%. Differences in seed quality and productivity of seeds depending on the conditions of the year of observation may indicate the necessity for measures for adaptation of the plants to harmful environmental factors.

The aim of the present work was to identify strawberry Fragaria × ananassa Duch. varieties, valuable for breeding on large-fruitfulness. The research objectives included the assessment of varieties by large-fruitfulness and the identification of sources of this trait, that allows to develop not only large-fruited, but also yielding varieties that are in demand in the market and it will lead to an increase in the production of strawberries, satisfying the population’s demand in poly-vitamin products. 64 varieties of strawberry were studied. The studies were carried out in the department “M. A. Lisavenko Research Institute of Horticulture of Siberia” of “Federal Altai Scientific Center of Agrobiotechnology” in the south of Western Siberia in conditions of a sharply continental climate in 2005-2018. The degree of large-fruitfulness was defined according to the generally accepted method, the assessment of large fruitfulness (average mass of berries) – according to the scale, proposed by N. P. Stolnikova for Siberian conditions. The coefficient of variation was calculated by the method, described by O. V. Masyukova. As a result of studies, it was found that 26 strawberry varieties had an average mass of berries less than 7.0 g, 17 varieties – 7.0-7.9 g, ten – 8.0-8.9 g, nine – 9.0-9.9 g, two – more than 10 g. The variability of large-fruited trait of the studied varieties seemed to be significant almost in all varieties, except for Alena and Zvezdochka varieties, in which the variability was insignificant and the coefficient of variation was 8.1-9.3 %. At Yaponka variety, the variability was average, the coefficient of variation was 13.9 %. For use in breeding the varieties Pervoklassnitsa and Tsunami with very large (12.8 and 10.3 g, respectively) and the varieties with large berries Alena, Atlas, the Bulgarian velikan, Bylinnaya, Vengerka, Vesper, Geyser, Yaponka (9.0-9.9 g and 10 varieties (8.0-8.9 g) were selected. It is necessary to use such strawberry varieties as sources of large-fruitfulness, which have a large-fruited degree of 5 points, 25 varieties turned out to be with this parameter. The parent forms selected for breeding turned out to be adapted to weather conditions during fl owering and ripening of berries, to recurrent spring frosts.

New data were obtained in favor of “Eastern transfer” – the transfer of material from the North-East to the South-West during the formation of the ridge system in Late Pleistocene. They consist in two positions: first, they are longitudinal furrows in the axial part of the ridges, which are fan-shaped split at their South-Western ends; second, the inextricable genetic link of the ridge relief with the spillways is confirmed. The Eastern transfer is interpreted as convincing evidence of the water origin of the ridge relief.
