Fagopyrum Esculentum Moench

The paper presents results of the complex research of different species of Fagopyrum (F. esculentum Moench, F. tataricum (L.) Gaertn., F. cymosum Meissn.) on rutin content and their usage prospects as a resource of flavonoids. Relation between rutin content in the overground mass and the plant colour was found. Biological significance of rutin, prospects of its usage as a diagnostic trait in selection, are also shown in the article. Bio-chemical and technological traits of F. esculentum varieties cultivated in the Far East Russia were also studied and reflected in the paper. We therefore examined rutin content in the overground phytomass of the three species of Fagopyrum on the phase of mass flowering and discovered that high indices belong to: F. esculentum (Izumrud variety) ‒ 3.8 %, F. tataricum (sample k-62 from Canada) ‒ 4.4 % and F. cymosum (k-4231 from India) ‒ 4.1 %.  Rutin content in the hull of common buckwheat ranged from 0.08 till 0.20 %. Maximum rutin quantity was determined in the hull of Ussurochka (35.7 kg/ha), and minimum (17.8 kg/ha) in the hull of Pri 7. The studies show that the ash content, obtained after burning the hull of F. esculentum (600°C) is in average 2 %. The following elements were found in the ash: potassium, sodium, copper, silver, calcium, magnesium, zinc, aluminum, manganese, iron, nickel, chromium, phosphorus, and their concentration depend on variety and type of raw material of F. esculentum. Key words: Fagopyrum esculentum, F. tataricum, F. cymosum, overground mass, hull, rutin   Izvleček V prispevku so predstavljeni rezultati kompleksne raziskave različnih vrst rodu Fagopyrum (F. esculentum Moench, F. tataricum (L.) Gaertn., F. cymosum Meissn.) o vsebnosti rutina in možnosti njihove uporabe kot vira flavonoidov. Ugotovljeno je bilo razmerje med vsebnostjo rutina v nadzemni masi in barvo rastlin. V članku je prikazan tudi biološki pomen rutina, možnosti njegove diagnostične uporabe pri selekciji oziroma njegov pomen pri selekciji. V delu so bile proučene tudi biokemijske in tehnološke lastnosti sort F. esculentum, ki jih gojijo na Daljnem vzhodu Rusije. Zato smo določali vsebnost rutina v nadzemnih delih treh vrst rodu Fagopyrum v fazi cvetenja in ugotovili, da visoki indeksi pripadajo: F. esculentum (sorta Izumrud) ‒ 3,8 %, F. tataricum (vzorec k-62 iz Kanade) ‒ 4,4 % in F. cymosum (k-4231 iz Indije) ‒ 4,1 %. Vsebnost rutina v luščinah navadne ajde je znašala od 0,08 do 0,20 %. Največja količina rutina je bila določena v luščinah Ussurochka (35,7 kg/ha) in najmanjša (17,8 kg/ha) v luščinah Pri 7. Študije kažejo, da je vsebnost pepela, pridobljenega po upopelnjenju luščin F. esculentum (600°C), v povprečju 2 %. V pepelu so bili določeni naslednji elementi: kalij, natrij, baker, srebro, kalcij, magnezij, cink, aluminij, mangan, železo, nikelj, krom, fosfor, njihova koncentracija pa je odvisna od sorte in rastlinskega dela vrste F. esculentum. Ključne besede: Fagopyrum esculentum, F. tataricum, F. cymosum, nadzemna masa, luščine, rutin

The Impact

The results of studies of anthropogenic landscapes functioning with an assessment on the processes of natural self revegetation are summarized. The principles of accelerated restoration of the ecological and aesthetic value of disturbed landscapes at the permafrost zone are substantiated, based on the data obtained during studying the selfrevegetation processes on disturbed complexes. Development of placer and ore deposits of mineral resources is leading to deep transformation of landscape and to destruction of soil-vegetable complexes. The processes caused by mining-technical activity are leading to variable mechanisms of degradation of soil and vegetables often having complex impact. Results of study of sustainability of soil-vegetable complexes to the impact of mancaused activity have showed the dependence from the structure of the soil profile and it characteristic, from the character of genetic horizons, frozen status of the landscape elements, form the structure and biomass and productivity of vegetation cover.

Socio-economic indicators of the Irkutsk region, Buryatia and the Far East, dynamics of their development in 2016-2017, and problems and prospects are considered in this paper. Today, the priority for the regions of Siberia and the Far East, which possess unique natural resources and a vast territory, is the complex task of increasing the living standard of the population and launching a new economic strategy. The Irkutsk region is one of the largest industrial regions of Russia. The city of Irkutsk was formed as an administrative, commercial and cultural-educational center. Currently, it is home to more than 50% of the urban population of the Irkutsk region. Some enterprises of the city have a machine-building profile. The production of food (more than 45% of the total volume), the construction material, and wood processing also play an important role. External migration has a significant impact on the demographic situation in the region. Most of the migration processes with the crossing of the boundaries of the region take place within Russia. According to statistical data, external migration can be divided as the three main flows of foreign citizens entering the territory of the Irkutsk region: the Central Asian direction (Uzbekistan, Tajikistan, Kyrgyzstan, and Kazakhstan 44.3%); the East Asian direction (China, Mongolia, DPRK, Japan, and Vietnam 30.8%); and the Western direction (Germany, France, and Poland). It should be also noted that 13.9% of all migrants are migrants from Ukraine, Armenia, Belarus, and Moldova, these are mainly young people of working age. The Baikal region is famous in Russia for its natural landscapes: there are more than 1,500 objects of excursion and cognitive significance (natural, architectural, cultural and historical monuments) in the region. The region has a great industrial potential that is of national importance. Several basic complexes and industries compile a modern industrial structure. There are opportunities for further development of the industrial production in the oil and gas industries, diamond mining industry, the production of composite materials, fibers and mineral fertilizers. On the Far East, priority is given today to the raw material economy and the related infrastructure facilities, including the modernization of the Trans-Siberian Railway and the Baikal-Amur Mainline.
