The botanical garden in Surgut is the northernmost in Western Siberia and one of the northernmost botanical gardens in Russia. It is the major point for promoting new agricultural and biological technologies to the Far North. Currently, the collection of ornamental plants of the Surgut botanical garden comprises about 200 species and varieties of herbaceous plants belonging to 60 genera and 32 families, and about 210 species, forms and cultivars of woody plants. The research objective is to study the adaptation mechanisms of some ornamental plants from the collection of the botanical garden using the up-to-date portable flavonoid and chlorophyll meter DUALEX. The research objects are five species of herbaceous plants of genus Iris L. - Iris hungarica Waldst. &Kit., Iris variegata L., Iris sibirica L., Iris glaucescens Bunge, Iris sulfurea C. Koch. and eight species of woody plants of genus Acer L. - Acer pseudoplatanus L., Acer rubrum L., Acer trautvetteri Medw., Acer tataricum L., Acer ukurunduense Trautv. & C.A. Mey., Acer spicatum Lam., Acer mandshuricum Maxim., Acer ginnala Maxim. The range of nitrogen balance (Nbi) in herbaceous plants varied from 32.2 to 39.7, and the chlorophyll content was from 48.1 to 58.6 mg/cm2. In woody plants, the content of chlorophyll (Chl) ranged from 23.9 mg/cm2 ( Acer spicatum ) to 31.3 mg/cm2 ( Acer rubrum ), i.e. only 1.3 times within the group species growing on one flank. The content of flavanols in woody plants ranged from 1.3 mg/cm2 in Acer mandshuricum to 1.9 mg/cm2 in Acer ukurunduense . The maximum values of Nbi, Chl indices for Iris hungarica and Acer pseudoplatanus are an adaptive reaction to growing conditions and indicate the formation of plantprotective functions. The pigment content of leaves in ornamental plants indicates their satisfactory physiological state, as evidenced by a slight variation in biochemical parameters among the tested groups of ornamental plants.
