Tilia cordata Mill. is considered to be the main tree species resistant to urban conditions and it is widely used in the greening of cities. The aim of the study is to assess the patterns of growth and development of small-leaved linden plantations in the urban environment. The research is based on the method of sample areas where continuous enumeration survey has been carried out. The study of urban greening objects was conducted using the methods of landscape assessment and complete enumeration of trees in alley plantings. It was found that Tilia cordata Mill. grows in all districts and zones of the city of Ufa, occupying 34.4% of green areas. During this research it was found that artificially created alley plantings of Tilia cordata Mill. are more well-kept and have well-developed crowns which create a tree shade sometimes 8-10 meters wide (the average crown projection being 7 m). Since alley plantings have repeatedly been pruned, trees in this area are characterized by a large increase in diameter and strong height growth stagnation. Thus, when studying linden plantings of the same age, a sharp difference in the size and shape of trees was observed.
Methodological aspects of microclonal reproduction of valuable tree species – triploid aspen and Karelian birch, which are important for enriching the gene pool of the main forest-forming tree species in the Republic and obtaining high-quality wood raw materials in the form of ornamental and decorative wood, are proposed.
The article describes the features of natural renewal of common pine in felled areas of the forest during continuous sanitary logging, in logging areas after logging, and on land that has come out of agricultural use. The estimation of growth indicators of common pine on the accounting areas, by the diameter and height of the trunks, was made, and its vital condition was determined . Measures are planned to successfully promote the natural regeneration of Scots pine in deforestation. In the natural and artificial reproduction of pine forests, they effectively perform protective, sanitary and other environmental functions, which meets the principles of sustainable and rational forest management. It is important to pay attention to timely forestry care in stands of common pine of various origins, which will allow us to solve the problem of increasing their stability and productivity at a qualitatively new level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
