Study of water regime and annual growth of shoots in woody plants growing on spoil dump Kedrovskiy coal mine

The Kuznetsk Basin is the largest in Russia in terms of the quantity of coal reserves and mining. In the result of coal mining there is a change of ter-rain, a full or partial soil disturbance, water, air and food regime of the soil, which leads to alteration of the ecosystem as a whole. In this regard, the eco-logical rehabilitation of technogenic lands becomes relevant and socially important problem. One of the criteria for evaluation of plant resistance to adverse environmental conditions is the stability of indica-tors of the water regime. The paper presents the results of a study of the water regime and growth of the annual escape of woody plants growing under the conditions of the dump coal mine "Kedrovsky", located in the Central part of the Kemerovo region. The object of the study was to trees Pinus syl-vestris L. and Betula pendula Roth., 10-15-years of age. Studied the following characteristics: annual growth of lateral shoots; free, bound and total wa-ter. The studies were performed according to standard techniques. The results of the experi-ments show a trend to reduce total water pine and birch trees growing under conditions of satiety. The study of the fractional composition of water showed that the studied species growing in terms of satiety, there is an increase in its associated forms in all periods of observation in comparison with the con-trol. The changes in fractional composition of water in the direction of increasing its connected form in woody plants under conditions of satiety, on the one hand, increases the resistance of plants and promotes the conservation of this species in ex-treme environment conditions, on the other hand, leads to slower plant growth, to reduce the intensity of metabolic processes. This fact is confirmed by the results of the study of growth of shoots of plants. In terms of satiety, despite the extreme liv-ing conditions for plants, marked increase in the annual escape as the Scotch pine and silver birch, however, at all-time of observations it is much less than in plants of control plot.
