| 摘 要： | 2010年6月在普洱良种繁育基地用20月龄的云南红豆杉(实生苗、顶枝扦插和侧枝扦插)容器苗定植,采用单因素随机区组设计,2011年12月对其生长量(树高、地径和侧枝发枝数)进行观测记录和结果分析。结果表明:3个处理的树高、地径和侧枝发枝数各处理间均存在极显著差异,树高、地径和侧枝发枝数生长表现最好的处理均是处理A即实生苗,树高和地径表现最差的均是处理C即侧枝扦插,侧枝发枝数表现最差的是处理B即顶枝扦插。

| Abstract: | In June, 2010,20 months of seedlings and top branch and branch cuttings of Taxus yunnanensis were planted in the container in Pu＇er seed breeding base, and the single factor was adopted to conduct randomized block design. In December 2011 the growth of tree height, ground diameter and collateral branches number were observed and analysed. The results showed that three treatments had significant difference in the tree height, diameter and collateral branches number. Treatment a （seedlings） displayed the best. Treatment C （branch cutting） showed the worst in the tree height and ground diameter. And treatment B （top branch cutting） had the worst collateral branching number. |
