摘要 汇集17个臭椿系号,以当地臭椿为对照,营造了臭椿无性系测定林。经多点造林测试,选出3个优良无性系,分别是臭椿824005、82001和箭杆2号,其材积生长量分别比对照提高30.2%~67.8%、30.2%~97.1%和26.7%~47.2%,生长表现优良,有较高的推广应用价值。 different clones of tree of heaven were collected and planted as the clonal test forest in contrast with native trees. Three good clones were selected through multi-plot planting test. They were clones 824005,820001 and “jiangan 2” with increase in volume growth about 30.2%~67.8%,30.2%~97.1% and 26.7%~47.2% compared with native trees respectively. These clones presented better growth and higher practical diffusion value.
