Embodiment
[0043] The difference between this embodiment and Example 1 is that the second MS basal medium adds different components, so as to test the influence of different mediums on the proliferation of adventitious buds:
[0044] Added the second MS basal medium of 6-BA 2.0 mg / L + ZT 0.5 mg / L + IAA 1.5 mg / L, the adventitious bud proliferation rate reached 5.8.
[0045] Added the second MS basal medium of 6-BA 2.0 mg / L + ZT 0.5 mg / L + IBA 0.3 mg / L, the adventitious bud proliferation rate reached 5.95.
[0046] Example 4
[0047] The difference between this embodiment and Example 1 is that the MS basic medium of 1 / 4 strength has different components added, so as to test the influence of different mediums on the rooting rate:
[0048] Added 0.3 mg / L NAA 1 / 4 strength MS basic medium, the rooting rate was 92.8%.
[0049] Added 1 / 4 strength MS medium with IAA 1.0 mg / L, the rooting rate was 92.5%.
[0050] Comparing the foregoing examples, it can be found that Example 1 can finally obt...

Abstract
The invention discloses a rapid asystasiella neesiana tissue culture propagation method which comprises the following steps: (1) inducing multiple shoots, namely, culturing explants taken in March by using an MS basic culture medium with 6-BA+NAA, taking out until the shoots are 3cm, separating axillary buds on two sides along stem cuttings, and transferring and inoculating with a first MS basic culture medium with 6-BA+ZT; (2) enabling adventitious buds to grow and proliferate, namely, cutting for dividing 2-3 multiple shoots generated through induction in the step (1) into one group, and transferring and inoculating into a second MS basic culture medium with 6-BA+ZT+NAA; (3) performing rooting culture of the adventitious buds, namely, cutting the clustered adventitious buds obtained through proliferation culture in the step (2) into single adventitious buds, and transferring and inoculating into an MS basic culture medium with 1 / 4 intensity with NAA; and (4) hardening and transplanting the regenerated seedlings. By adopting the method, asystasiella neesiana regenerated plants can be rapidly obtained, and industrial production can be facilitated.
Description
