Tagirov B.B., Yanbaev Yu.A., Tagirova A.A., Redkina H.H. INDIVIDUAL VARIABILITY OF HEIGHT INCREMENT OF SCOTS PINE`S UNDERGROWTH IN ABANDONED AGRICULTURAL LANDThe article contains results of analyses of individual variability of annual height increment of Scots pine (Pinus sylvestris L., Pinaceae). Region of research is presented by forest-steppe of Bashkir Trans-Urals, where in recent decades a large-scale of natural reforestation of Scots pine in out-of-use agricultural land — abandoned arable, hayfields and pastures is occurred. 30 areas of Scots pine`s self-seeding were selected on the territory of Uchaly region of Republic of Bashkortostan on a provisional transect `north-south` length of nearly 100 km. The amount of the annual increment in height in the years 2009–2013 was measured at 4 000 copies of undergrowth (30 plants / year for each test area). The study proved that the variability of a feature within separate reforestation areas is mainly determined by genetic characteristics of undergrowth rather than by environmental conditions.Key words: abandoned agricultural land, growing over of woody and shrubby vegetation, Scots pine, undergrowth, variability, annual increment in height.
