Growth and phenological development of Caucasian species Lilium L. (Liliaceae Juss.) in Kola Subarctic

In the Polar-alpine botanical garden (67o 38' N lat, 33o 37' E long.) 17 samples 3 species of Lilium L. from Caucasus (L. kesselringianum Miscz., L. monadelphum M. Bieb. and L. szovitsianum Fisch. et Avé-Lall.) were tested. At the present time collection contains 3 kinds 7 samples of three kinds. Authors studied growth and phenological development of introductional plants of genus Lilium beyond the Arctic Circle. As a result of researches is established, that the periods of currence of phenophases and their duration may vary in different years depending on weather conditions. The absence or irregularity of fruiting is explained by climatic conditions, in particular, short periods of vegetation. The results of the ecological-geographical analysis testify that the plants of a sort Lilium submit to general laws of resettlement of plants on Polar North. For the practice of green building in cities and towns of the Murmansk region, we can recommend the studied types of Caucasian lilies. At the cultivation of plants in artificial plantings the preference should be given back of a vegetative to a way of duplication of plants.
