Tsitoekologicheskie Issledovaniya Berezy Povisloy (Betula Pendula Roth)

Tsitoekologicheskie issledovaniya reshayut odnu iz vazhneyshikh problem biologii - vzaimootnosheniya organizma so sredoy. Vazhneyshey zadachey tsitoekologii yavlyaetsya izuchenie adaptivnykh izmeneniy vnutrikletochnykh protsessov v otvet na kolebaniya temperatury, osveshcheniya, khimicheskogo sostava, davleniya, drugikh abioticheskikh elementov sredy, v tom chisle i antropogennykh faktorov: zagryazniteley khimicheskoy i fizicheskoy prirody.Ob"ekty issledovaniy: kletka i geneticheskiy apparat kletochnogo yadra, poetomu tsitoekologiya vidov tesno svyazana s ikh tsitogenetikoy. Tsel' nastoyashchey raboty sostoyala v provedenii sravnitel'nogo izucheniya tsitogeneticheskikh kharakteristik u semennogo potomstva berezy povisloy (poluchennogo ot svobodnogo opyleniya i samoopyleniya) v ekologicheski bezopasnykh usloviyakh i pri antropogennom zagryaznenii. Tsitogeneticheskie kharakteristiki berezy povisloy (tsennoy dekorativnoy i lesoobrazuyushchey porody) mogut byt' ispol'zovany dlya monitoringa sostoyaniya okruzhayushchey sredy, dlya predvaritel'noy geneticheskoy otsenki kachestva semyan materinskikh derev'ev v zavisimosti ot ikh genotipa, sposobov opyleniya, usloviy proizrastaniya, chto mozhet predstavlyat' interes dlya ekologov, lesnykh selektsionerov i semenovodov.
