Embodiment 1
[0030] Take the petiole of wild Baoshan Viola as the explant, wash it with running water, cut it into 0.5cm 2 Small pieces of 0.1% HgCl 2 Soak in water for 10 minutes, then rinse with sterile water 4 to 5 times, and inoculate on the MS basic medium of 1mg / L 6-BA+1mg / L NAA. . The culture conditions after inoculation to before hardening are: 22-25°C, 12 hours of light. One week after inoculation adventitious shoots were formed (eg image 3 ), when the height of the adventitious buds is about 2 cm, transfer them to 1 / 2MS medium to promote their root growth. After 2 weeks of rooting and cultivation, open the bottle cap to harden the seedlings, move them into the cultivation soil, and cover them with plastic bags to maintain a certain humidity. Remove and water daily. The survival rate is greater than 80%. After 4 to 5 weeks after being moved into the culture soil, the tissue-cultured seedlings have the same shape as the wild seedlings, grow robustly, open hidden flowers, set ...
Embodiment 2
[0032] Take the leaves of wild Baoshan Viola as explants, wash them with running water, and cut them into 0.5cm 2 Small pieces of 0.1% HgCl 2 Soak in water for 10 minutes, then wash 5 times with sterile water, inoculate in hormone ratio of 1mg / L KT+1mg / L 2,4D, white callus will be formed 3 days after inoculation, and obvious callus will be formed after 3 weeks. Injured tissue (such as figure 2 ). The callus was inoculated on MS medium with a ratio of 1mg / L 6-BA+1mg / L NAA, and adventitious shoots formed within 1 to 2 weeks. The culture conditions after inoculation to before hardening are: 22-25°C, 14 hours of light. When the resulting adventitious buds are about 2 cm high, transfer them to 1 / 2 MS medium to promote their root growth. After rooting and culturing for 3 weeks, open the bottle cap to harden the seedlings, spray a little water, cultivate them in a sterile room for 2 days, and then transfer them to the greenhouse for cultivation. After 1 day, remove the seedlings...
