| Abstract: | The rooting culture of Dendrobium candidum wall was carried out with differentiation seedlings as test materials, by means of conventional bottles-type tissue culture system and bag-type tissue culture system. The results showed that tissue culture seedling produced from conventional bottles culture system and bag culture system showed no significant differences and they had some common characteristics: developed root system, 100 percent rooting rate, strong root, good quality, over 90 % survival rate of transplants, and so on. However, some characteristics of bag-type tissue culture system were better than that of the conventional bottles-type tissue culture system, such as sterilizing of culture medium, the seeding efficiency, contamination rate, survival rate of transplants, the utility of cultivate space, the efficiency of seedling exercising, and so on. The results of this study have confirmed the fact that the bag-type tissue culture system could significantly improve the production efficiency as well as could achieve the effects of saving energy increasing efficiency. |
