As a resultof the investigationsfor the first time arerefined the taxonomicalcomposition that include 23 species, 3 hybrids and 26 forms and cultivars. The questions ofgrowth and development, also the peculiarities offlowering andseed-bearing are studied. Thesustainability of the species and forms ofthe genus Abiesto unfavorable environmental factors i. e. to drought hardiness experimentally are established. The peculiaritiesof seed andvegetative propagationare investigated. For the first timeare tested variousways ofgrafting for decorative formsoffir in thesoil and climatic conditions. Based on the analysis of obtained data are proved the perspectiveof breeding somespecies andgarden formsby vegetative ways. The optimal grafting terms,graftingmodalities and their modificationswith reference to the conditions are recommended. A result of investigationsselected andrecommended for usein green buildingthe mostornamental speciesand cultivars offir.
