摘要： 新疆杨属白杨派种群。白杨派一个共同的特性是扦插育苗生根难,原因是在枝杆生长过程中根原基分化数量少,比青杨派和黑杨派少4～5倍。所以,新疆杨扦插育苗的着眼点应放在愈伤组织生根上,尤其在北方寒冷区域,育苗成败的关键就在于扦插期的管理措施能否符合生根要求。根据研究人员3年的试验结果,提出对传统育苗技术进行改进的意见,与同行探讨,共同促进新疆杨扦插育苗技术进步。

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
