FEATURES ADAPTATION REARRANGEMENTS NEEDLES PINUS SYLVESTRIS L. UNDER WASTE DUMP COAL CUT "KEDROVSKY" ^{[№ 6 ' 2016]}
In the Kuzbass Pinus sylvestris L. is one of the suitable species for the growth of the waste industry in the dumps, but the identification of relevant growth conditions of its biological requirements on the waste dumps so far not been sufficiently studied. The complex of various diagnostic methods of P. sylvestris needles in the territory of the waste dump coal mine "Kedrovsky" was spend. Defining the parameters of the water regime of the leaves (water scarcity, loss of subsistence, water retention), was carried out by repeated weighing method, peroxidase activity — by A.N. Boyarkin method, ascorbic acid content — by titrimetric method with using 2,6-dichlorophenol sodium and content of tannins — by Leventhal-Neubauer method in A.L. Kursanov modification. Some specific features of adaptive rearrangements in P. sylvestris L. on-planned waste dumps revealed. In explored plants showed an increase of the area of vascular bundles and resin ducts. The changes of water regime of pine needles toward enhance water retention and reduce the daily losses been established. An increasing of peroxidase activity and tannins, reducing activity of ascorbic acid. Identified anatomical and morphological, physiological and biochemical adjustment in P. sylvestris L. needles can be seen as adaptive reactions aimed at the survival of plants in terms of environmental waste dump. The experimental data can be used in the assessment of woody plants and as an informative parameter in the surrounding environment bioindication.
