| 通过采用不同的留叶数目、 ABT1 号质量体积浓度、 100 mg/L ABT1 号处理时间以及扦插基质
等因素对缅甸树萝卜（Agapetes burmanica）枝条进行扦插繁殖对比试验，结果表明：（1）留 3~5 片叶的
枝条生根率最高，为 46.7%；（2）缅甸树萝卜枝条的生根率随 ABT1 号质量体积浓度的增加呈现先升高然
后下降的趋势，质量体积浓度为 100 mg/L 时，生根率最高，达 46.7%；（3）通过速蘸 100 mg/L ABT1 号
10 s、 10 min 和 1 h 处理插穗，插穗生根率分别为 26.7%、 46.7%、 40.0%，其中 100 mg/L ABT1 号浸泡插
穗 10 min 生根率最高；（4）缅甸树萝卜枝条在 V 珍珠岩： V 蛭石： V 树皮 =1:1:1 和水苔两种扦插基质中的生根
率分别为 30.0% 和 46.7%，表明水苔较适宜缅甸树萝卜的扦插生根。将缅甸树萝卜生根插穗进行移栽，成
活率可达 81.0%。 |

| Abstract: |
| The cutting propagation experiment was carried out by using Agapetes burmanica branches under
different conditions, such as number of reserved leaves, ABT1 concentration and treatment time, and mediums.
The results showed that: (1) The rooting rate of branches with 3~5 reserved leaves was the highest, which was
46.7%; (2) With the increase of ABT1 concentration, the rooting rate of the branches increased first and then
decreased, and when the concentration was 100 mg/L, the rooting rate reached a maximum of up to 46.7%; (3)
When we dipped the cuttings into 100 mg/L ABT1 for 10 s, 10 min and 1 h, the rooting rates of cuttings were
26.7%, 46.7%, and 40% respectively, which indicated that the best treatment time was 10 min; (4) We used
V
perlite : Vvermiculite : Vbark = 1:1:1 and sphagna as two cutting mediums of A. burmanica branches , and the rooting
rates were 30.0% and 46.7% respectively, which indicated that sphagna was more suitable for cutting rooting in A.burmanica. The transplant survival rate can reach 81%.This research has successfully explored the best conditions
for the cutting propagation of A. burmanica, which has important practical significance for the sustainable
utilization and conservation of Agapetes plant resources. |
