Abstracts |
The microstructure of the mycorrhizal and fungal species of Changnienia amoena, a monotypic endemic species in China, was investigated. Results showed that the microstructure of the mycorrhiza of wild C. amoena has the typical mycorrhizal structure as of orchids. Isolation was carried out twice and 36 strains were isolated which belong to Basidiomycotina and Deuteromycotina wherein the superior genus is Fusarium. A total of 16 fungal strains were inoculated to tissue-cultured seedlings of Dendrobium sinense and 10 of them promoted the growth of seedlings at different levels after inoculation. The average height increment of the seedlings inoculated with the strain DHL-19 was significantly higher than the control and the average height increment of the seedlings inoculated with two fungal strains (DHL-16 and DHL-17) was also significantly higher than the control. The primal strains were reisolated and a few pelotons were observed from the three treated seedlings. It is concluded that DHL-16, DHL-17 and DHL-19 should be used as the mycorrhizal fungi for orchids. |
