A. V. Bgatov, O. N. Sorokoletov, V. A. Mamakhatova, V. M. Tokaev
Gigantism of plants in many cases is due to release of endogenous carbonic gas that goes through their roots. It characterizes the initial phase of photosynthesis. Our experiments study vegetation of Yakut and Altai Mountains. The paper also gives examples of vegetation occurrence on tectonic faults, where there is usually no soil cover. This vegetation is related to depth gases, principally carbon dioxide. The examination of gas and mineral nutrition of plants (PFM) in various parts of Siberia resulted in the firm conclusion that depth gases decisively contributed to the giant natural growth in such areas. Other endogenous gases, such as nitrogen dioxide, carbonic oxide, ethane, ethylene, methane and others, rarely influenced on vegetation growth and development in the young folded zones. Flora is sensitive to environment changes and, above all, in terms of nutrition. The proportion of endogenous CO2 clearly prevails over that of exogenous one, i. e. atmospheric CO2. Thus, the dark period of photosynthesis begins from roots which absorb CO2 combined with soil water through carbonic acid.
Key words: area of mineral nutrition, carbon dioxide, photosynthesis, Verkhoyanye, Gorny Altai, ecogeology, soil, ground, natural growth.
