Abstract: Populousbolleana belongs to Section leuce community.A common weakness existed in Section leuce in its cutting seedings is that it is very difficult to root.The reason for this lies in less root primordium secreted in the duration of stem growing,being four or five times less than Section pachamaca and aigereis.Therefore,the emphasis for cutting seedings of populousbolleana should be put on root from healing tissue.The key to successful seeding particularly in northern cold region is determined on whether the management in cutting period can meet the requirements for root.In accordance with our three years test results,the paper puts forward improvement for traditional seeding technique so as to jointly promote technological progress in populousbolleana cutting seedings.

Key words: Populousbolleana, Cutting seedings, Methodological improvement
