Research Progress on the Effects of Environmental Factors on Tissue Culture and Greenhouse Planting of Dendrobium officinale

This paper reported the research progress of tissue culture and greenhouse planting of Dendrobium officinale. The effects of environmental factors such as light,temperature,medium,hormone and additive on cultivating strong seedling and enhancing the survival rate of D. officinale were discussed. D. officinale seed germination rate was very low in natural condition,tissue culture technique was the best way to promote the rapid propagation of D. officinale. Furthermore,the core technology of D. officinale artificial cultivation was to move the tissue culture seedlings into greenhouse. Studies had shown that orchids endophytes,light,temperature and other environmental factors affected the production and quality of D. officinale greenhouse cultivation,so how to effectively manage and utilize these environmental factors to improve the production and quality would be the focus of future research.
