Abstract:
Objective:As a source of energy for Armillaria mellea and Gastrodia elata，the woods species as fungus material of G.elata are diverse and play an important role in the development of G.elata industry. In order to explore the impact of different woods species on the quality of G. elata，the plant origins and lignocellulose content of the woods，the yield and quality of G. elata per unit area were systemically analyzed through literature research and investigation on production bases. Method:G. elata and its cultivated woods were collected from four main producing areas （Guizhou, Yunnan, Hubei, and Shaanxi），and the the plant origins of the woods were identified by DNA fragments. The content of lignocellulose in the woods was determined by high-performance liquid chromatography and loss-on-ignition method. The content of polysaccharides of G. elata from these 4 areas was determined by Phenol-sulfuric acid method. The yields and polysaccharide content of G. elata cultivated with different woods species were compared and their correlation with the woods was analyzed. Result:The woods as fungus material of G. elata were diverse in species, and betulaceae was the most widely used species in cultivation of G. elata. There were differences in the composition ratio of lignocellulose in the woods. Nyssaceae had the highest cellulose content，Moraceae had the highest hemicellulose content and Rosaceae had the highest lignin content. Different woods species had certain effects on the yield and polysaccharide content of G. elata. The maximum yield of G. elata was 1 285.51 g and the lowest yield was 379.30 g. The average mass fraction of polysaccharide content was 241.1 mg·g-1，with a range of 87.95-411.2 mg·g-1. The yield and polysaccharide content of G. elata were highly positively correlated with the cellulose content of the woods, and highly negatively correlated with the lignin content. Conclusion:Different woods have a significant impact on the yield and quality of G. elata. Choosing the appropriate woods species will be beneficial to the absorption of nutrients for A. mellea and the yield increase of G. elata. This study can provide a scientific basis for the selection of woods species during the cultivation of G. elata.
