Abstract: In order to explore if Populus×euramericana cv. Quanhong in the Beijing area can be successfully introduced, the author adopted the breeding method, the field observation method, the pigment measurement method, the resistance analysis method, the market research, and so on. Many studies were conducted on Populus×euramericana cv. Quanhong introduced from Puyang, He’nan Province to the Beijing area. The results showed that: Populus×euramericana cv. Quanhong could normally grow, and complete the activity cycle of its full life. It could be easily propagated, the reproductive survival rate of its high graft was 83%, that of low graft was 85%, that of the hard branch cutting was 88%. The plant was colorful and stable, the anthocyanin content was high, the value of the anthocyanin content was 0.0383 mg/g, and 83.25% higher than Zhonghongyang with the purple leaves, and 100.52% higher than Jiayang (Populus canadensis Moench) with the green leaves. The resistance performance was good, and was hardy and resistant of barren. The economic value was high, the price of the high graft seedlings was 2 times higher than Zhonghongyang in the market. According to the judgment based on the introduction standard, Populus×euramericana cv. Quanhong could be successful introduced in the Beijing area, and meanwhile, for 2 years of cultivation and observation, the key points of cultivation and management techniques of the Populus×euramericana cv. Quanhong were achieved, and the references for the further propagation and cultivation were provided.
