The article discusses morpho-functional features of 25 species of woody subtropical plants (Acca sellowiana (O.Berg) Burret, Myrtus communis L., Murraya paniculata (L.) Jack , Coussapoa microcarpa (Schott) Rizzini, Cascabela thevetia (L.) Lippold, Podocarpus macrophyllus (Thunb.) Sweet, Podocarpus salicifolius Klotzsch & H.Karst. ex Endl., Phyllanthus juglandifolius Willd., Nandina domestica Thunb., Asparagus falcatus L., Ficus pumila L., Ficus cyathistipula Warb., Ficus binnendijkii Miq., Ficus retusa L., Ficus sagittata Vahl, Cinnamomum camphora (L.) J.Presl, Laurus nobilis L., Olea europaea L., Ligustrum japonicum Thunb., Ceratonia siliqua L., Tamarindus indica L., Pittosporum tobira (Thunb.) W.T.Aiton, Camellia japonica L., Magnolia obovata Thunb., Hibiscus sinensis Mill.) growing in the greenhouse of the Botanical Garden of Samara University. To assess the adaptability of the species, the following parameters are used: the reflectivity of the leaves (upper and lower sides), the thickness of the leaf blade, the specific area of the leaves (SLA), the content of caratinoids and chlorophylls (a, b). The collection of leaf material was carried out during two growing seasons. The analysis of the parameters takes into account climatic factors, such as average monthly temperatures, air humidity, illumination. In the species studied by us, the values of the specific leaf area index range from 58 to 363 sq.cm / g, the thickness of the leaf blade from 100 to 305 microns. During the analysis, a correlation (average conjugacy) was established for the studied species the thickness of the leaf blade with the reflection of the leaf blade (R=0.65) and the content of photosynthetic pigments hl.a (R= -0.79) and carotenoids (R= -0.59), illumination (R=0.43).
