Features of the photosynthetic activity of millet (Panicum miliaceum L.) in drought conditions

In the Pre-Kama zone of the Republic of Tatarstan, the main limiting factor of the yield of most crops is the drought. One of the ways of solving this problem is the selection of early ripening varieties, able to form seed harvest before the onset of adverse conditions. This paper presents a comparative characteristics of samples of millet (Panicum miliaceum L.) of mid-early and mid-season groups in terms of photosynthetic activity. We revealed the significant differences in area and dry biomass of leaves, photosynthetic potential of the samples of different maturity groups. Significantly lower values of some indicators of photosynthetic activity of mid-season group are due to drought conditions, coinciding with the functioning of assimilation surface. In dry weather conditions, the productivity of the main shoot is highly affected, directly and indirectly, by economic coefficient of the main panicle, the photosynthetic potential of leaves of the plant in general and the photosynthetic potential of the leaves of the lower and middle tiers

Evaluation of resistance to lodging of buckwheat varieties on the basis of anatomical features

Lodging crops is one of the reasons for shortage of crops and reducing its quality. For common buckwheat, the tendency to lodging is one of the factors limiting the production of this valuable crop. At the moment, the main area under buckwheat in Russia is taken by the varieties created on the basis of new morphobiotypes: restrictedly branching, determinant, with the physiological determination of growth. The present study aims at evaluating the resistance to lodging varieties, from different modern selections of buckwheat in Russia. We used the method of anatomical studies. It was found that the capacity of growth of woody tissues (sclerenchyma and wood) in the stem of buckwheat can serve as an indicator of resistance to lodging. Quality varietal differences in the anatomical features have not been found. The varieties significantly differed in area of lignified tissues in cross sections of the stem; this feature manifests itself in different varieties, regardless of their affiliation to a particular morphobiotype. It was concluded that in the process of selection of significant increase in thickening lignified tissues of buckwheat varieties did not happen. In addition, the positive correlation of mean strength between the area of woody tissues and the stem thickness and root maintenance of plants

Pollen productivity and fertility of pollen in the genus Fagopyrum mill

In recent years, a lot of hopes to improve buckwheat breeding are set on interspecific hybridization. To improve the efficiency of hybridization and in further successful seed reproduction of plants the quantity and quality of pollen released are of great importance. The objective of this paper was a comparative evaluation of pollen productivity and fertility of Fagopyrum esculentum Moench, Fagopyrum tataricum (L.) Gaertn. and Fagopyrum giganteum Krotov pollen. In this paper was used a comparative-embryological method and iodine method for pollen fertility determination. The development of anther in all three species happened in a similar manner, the difference was in the number of developing mother cells of microspores in the anther nest. Here were calculated average and potential pollen productivity of a flower, and p/o ratio of three representatives of Fagopyrum Mill. Realization of potential pollen productivity prevents violations during embryological processes. All three representatives of the genus revealed pauses in the development of sporogenous tissue and abnormalities in meiosis. Cytomixis was found only in Fagopyrum esculentum. The number of normally developed stamens in Fagopyrum esculentum and Fagopyrum giganteum was close to eight and in Fagopyrum tataricum samples was 4.9 and 6.0. The weakening of control over the development of Fagopyrum tataricum outer circle stamens is due to the fact that pollen from autogamous species produces more than it is necessary for its self-pollination. In all three species was discovered significant percentage of sterile pollen. Even in favorable for the plant's growth and development conditions the pollen fertility of Fagopyrum tataricum and Fagopyrum giganteum tetraploid sample did not exceed 56 %. On the example of Fagopyrum esculentum there was proved a significant impact of drought on pollen fertility

The historic city as an object of cultural tourism (on the example of Yelabuga)

This paper deals with the experience of the existence of historic cities, their opportunities as centers for tourism development. At present, there are 41 historic settlements in Russia with different status. The tourist appeal of historic cities is determined primarily by their historic and cultural heritage. In recent years, such form of tourism as cultural has become more popular. Among the objects of cultural tourism is the historic and cultural heritage in its material and non-material, intangible forms. These are historic territories, including historic cities, architectural structures and complexes, archaeological excavations, art and historic museums, folk crafts, festivals, folklore, household ceremonies, traditional values, activities and the daily life style of the local population. Within the framework of cultural tourism, an individualization of demand occurs. Travelers are interested not only in getting acquainted with the well-known sights, but also in a kind of "immersion" in the historic environment, in the knowledge of the traditions and customs of the local population. Management of their historic and cultural heritage is carried out, for the most part, by reserve museums. The project activity of Yelabuga Reserve Museum is being studied as a means to increase the tourist flow and attract new partners

The author reviews several projects devoted to the heroism of Soviet people during the Great Patriotic War. She characterizes the virtual projects, i. e. the project by TASS IA – “The Great Patriotic War through the eyes of Soviet journalists. TASS presents the frontline reports and newspaper articles of 1945” (January 19 – May 16, 1945); series of articles by Udmurtia information agency (covering the period of January 30, 1942 – May 9, 1945 as presented in the newspapers). The author compares these two projects to the NAB project “One hundred days before the Great Victory. Belarus newspapers in 1945” (January 30 – May 9, 1945) by the goals, contents and depth, and completion. The projects follow the day chronicle on the verge of the Victory, demonstrate the heroism of people in the front and behind the lines, and use information potential of historical newspapers. The author also characterizes the project by Gomel V. I. Lenin Regional Universal Library “The Victory Echo” (May 9, 1945–2020) and the joint multimedia project by Belarus Telegraph Agency and Belarus State Museum of the History of the Great Patriotic War: “The Victory chronicle: The living need the memory…” This experience can be used for designing similar virtual projects and other digital information resources.Рассмотрено несколько проектов, посвящённых подвигу советского народа в Великой Отечественной войне.
