The use of perennial decorative lianas in vertical landscaping in the city of Samarkand

\nLiana species is a well-growing plant with moderate humidity and moderate temperatures. Therefore, in the conditions of Uzbekistan, some species are most common. As with other ornamental plants, different ways of propagation of lianas have been developed, and it is important to study in which environment the methods are effective. Liana species reproduce using cuttings and seeds. The positive effect of lianas on Urban Environmental Quality (reducing the concentration of dust in the air, reducing noise intensity, cleaning the air from gasoline vapors, mastering carbon dioxide, etc.) is directly related to its environmental sustainability, which in particular manifests itself in maintaining optimal gas balance, maintaining improved radiation, heat and acoustic regimes. It is known that the sanitary and hygienic role of greened urban areas in conditions of increased man-made pressure is a means of eliminating the harmful effects of man-made pollution on urban residents. During the study, 12 species of perennial lianas recommended for landscaping the city were studied.\n
