摘　　要：研究了窄冠白杨6号的花芽数量,花序长度及杨絮重量,发现大田情况下,窄冠白杨6号败育,无飞絮污染,而在温室条件下可育,但单株杨絮量仅为普通毛白杨雌株的15.6%。说明窄冠白杨6号作为行道树或用于绿色通道建设,不会产生飞絮污染,同时又可作为进一步杂交育种的母本。Narrow crown white poplar No. 6 （Poplus ×leucopylamidalis 6） was studied on flower buds number, inflorescence length,andcatkin weight. It was found that female flower of narrow crown white poplar No.6 aborted in the field, and there was no flying poplar catkin pollution. While in the greenhouse, the poplar breed became fertile, with as little catkin weight as 15.6% catkin weight of female Chinese white poplar. Summarily, narrow crown white poplar No.6, with so little catkin, could be use as street tree, and is suited to green channels., as well as the female parent of crowing.
