| Abstract: |
| In order to realize the open tissue culture and proliferation of Acacia mangium × A. auriculiformis,
an open tissue culture and proliferation cultrue system of A. mangium × A. auriculiformis was established. In this
paper, A. mangium × A. auriculiformis were used as test materials. An orthogonal design was used to study the
effects of growth regulators 6-BA, IBA, and NAA on the proliferation under the condition of no sucrose, aiming to establish A. mangium × A. auriculiformis open tissue culture proliferation culture systems. The results
showed that different concentrations of 6-BA, IBA and NAA had significant effects on the proliferation of
A. mangium × A. auriculiformis; the effects of different growth regulators on the proliferation of A. mangium ×
A. auriculiformis were as follows: IAA > 6-BA > IBA. The best growth medium for open tissue culture is: MS
+ 2. 5 mg·L
- 1
6-BA + 0. 1 mg·L
- 1
IBA + 1. 0 mg·L
- 1
IAA + 0. 2 g·L

chlorothalonil, the multiple of
proliferatione achieved 2. 97. The research results lay an important foundation for the further establishment of a
perfect open tissue culture system of Acacia, and also provide an important reference for the related research of
other tree species. |
