Sea buckthorn (Hippophae rhamnoides L.) in the plant world is a leader in the variety of useful properties and their practical use. The introduction of a new type of forestry production in Uzbekistan sea buckthorn plantations involves the formation of new approaches to growing own-rooted seedlings and vegetative propagation of promising forms of sea buckthorn. The aim of research was to study the vegetative propagation capacity 6 ecotypes buckthorn local populations and varieties of “The Gift of the Katun” (Russia) in the open field and in greenhouses conditions automatically controlled artificial fog. Studies have shown that sea buckthorn cuttings characterized by a high regenerative capacity in their rooting in the open ground. Best indicators seedling growth was observed in the fertile soil of (74,1±4,59 cm of height 16,8±0,3 mm in diameter) the worst - in normal soil (43,3±1,41 cm and a height of 3,0±0,12 mm diameter). The share of standard seedling is high among seedlings grown in the fertile soil (73,1%), low - in ordinary soil and 25,0% in the open sandy greenhouse (25,9%). Cuttings varieties of sea buckthorn “Dar Katun” better rooted in the sandy substrate (81,2-82,4%) but grow better in fertile soil - at the end of the growing season, they had a height of 78,7±3,98 cm and 6,8±0,25 mm diameter. It is better to take root cuttings Paltaus (78,6%) and Chirchik ecotypes (77,5%). Worse rooted cuttings Tanhazdaryans ecotype (64,5%). Preservation of seedlings of various ecotypes at the end of the growing season was 74,5-81.4%.
