Study on Cuttage Propagation Technology of Agapetes burmanica
()
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.
Key words:  Agapetes burmanica; cutting propagation; rooting rate
