| 摘 要： | 本研究针对解决杨树城乡造林绿化结种飞絮问题为目的,选育无絮、速生、抗虫性强的品种定向培育,既可获得速生丰产,又可根除飞絮之害。通过从天然杂交实生后代选优及引进的优良无性系中的无絮品种进行树高、胸径、冠幅生长量及对桑天牛的抗性进行比较试验,结果表明:汉选1号、汉选2号、汉选4 号、中新1 号等无絮品种生长量均比对照品种Ⅰ-69 杨大,可用于城乡绿化造林。 |

| Abstract: | In order to solve problem of flying floccus in seed-bearing of afforestation with Populus in both urban and rural areas, the study was made to select variety of non-floccus, fast growing and strong resistantce to pest insect for directive breeding, which can obtain not only fast growing and high yield, but also eliminate damage of the flying floccu. Through comprative trial on tree height, D.B.H, crown increment and resistantce to Apriona germari from elite selection of natural hybrid cutting and late generation, and non-floccus variety of introduced improved clone, the result showed that the increment of non-floccus varieties of Hanxuan No.1, Hanxuan No.2, Hanxuan No.4 and Zhongxin No. 1 were bigger than I-69 Populus from the contrasted varieties which can be used in afforestastion of urban and rural areas. |
