Abstract

Studies of morphometric features of seven introduced taxa of bird cherry (genus Prunus L.) were carried out on the basis of a unique scientific installation «Collection of living plants of the Polar Alpine Botanical Garden Institute» (registration number 499394). The morphometric parameters of the leaf blade, generative and vegetative shoots and flower were studied, and the level of their individual variability was estimated by calculating the coefficient of variation during introduction into the Arctic zone of the Russian Federation (using the example of the Kola Peninsula). A very high level of variation has a parameter - annual linear growth - it is characterized by the greatest variability for all taxa. The least variable parameter is the diameter of the flower. 68 % of the values of all measured parameters have an average level of variability. The study of morphometric features of seven alien species Prunus L. conducted on the basis of the Collection of living plants of the Polar Alpine Botanical Garden Institute revealed that most of the labile symptoms found in P. virginiana, P. pensylvanica, P. padus and least - in P asiatica and P. maackii. The taxa P. padus L. f. mlorata Almquist and P. padus subsp. borealis (Schubeler) Cajander are ranked intermediate.
