- 摘 要：以金叶杨、全红杨、毛白杨、红叶杨、107杨、108杨、214杨为试材，通过硬枝扦插繁殖，研究分析了不同品种扦插苗一级根长、二级根数、根鲜重、根干重、比根长、根系活力、萌芽率、新梢长等8项生长指标变化，比较不同杨树品种在容器育苗扦插繁殖中的生长特性。结果表明：7个杨树品种中红叶杨生长最好，表现出植株地上部分、地下部分和植株综合生长特性均最好，其中，一级根最长、二级根数最多、根干重和根鲜重最高、萌芽率最高；其次为214杨，表现出植株地上部分生长并列最高、地下部分和植株综合生长特性较好，其中，一级根最长、二级根数较多、比根长最高、萌芽率较高、新梢生长量最大。全红杨、毛白杨、108杨、107杨生长中等，其中，全红杨二级根数最多、一级根较长；毛白杨一级根较长、根系活力最强；108杨一级根较长、根鲜重较高、根系活力较强；107杨的地上部分生长较好、二级根数量较多，比根长较大。金叶杨生长最差，表现出植株地上部分、地下部分和植株综合生长特性均最差，其中，二级根数最低、根干重和根鲜重较低、新梢生长量较低。总之，容器育苗扦插繁殖中红叶杨和214杨的苗木质量最好。

- Abstract:With gold leaf poplar,full red poplar,Chinese white poplar,red leaf poplar,107 poplar,108 poplar,214 poplar as materials,and by hardwood cuttings,primary root length,secondary root number,root fresh weight,root dry weight,length and thickness ratio of roots,root activity,germination rate,new shoots length of plants were studied in order to understand poplar growth characteristics of different varieties in propagation of cutting and potting.The results showed that red leaves poplar grew best among seven poplar varieties,which were the best on characteristics of aboveground andunderground part of plants,all plant growth,primary root length,the secondary root number,root fresh weight,root dry weight and germination rate.Followed by 214 poplar,its grew best on growth characteristics of aboveground part,same as red leaves poplar,primary root length,length and thickness ratio of roots,shoot length,better on growth characteristics of underground part and all plant growth,secondary root number,germination rate.Full red poplar,Chinese white poplar,107 poplar,108 poplar grew in a general way.Among them,full red poplar had maximum on secondary root number,longer primary root；Chinese white poplar had the strongest root activity and longer primary root；108 poplar had longer primary root,more root fresh weight and stronger root activity；107 poplar grew better on aboveground part of plants,had more secondary roots,longer length and thickness ratio of roots.Gold leaf poplar grew worst in all varieties and on above ground and underground part of plants,all plant growth,which had a minimum of secondary root number,fewer root fresh weight and root dry weight,shorter shoots.In a word,seedling quality of red leaves poplar and 214 poplar was the best in cutting propagation of container and among 7 varieties.
