摘要
目前关于暗褐网柄牛肝菌营养生理方面的研究较少,未见暗褐网柄牛肝菌子实体不同生长阶段中小分子碳水化合物变化规律相关报道.本研究对暗褐网柄牛肝菌子实体不同生长阶段的子实体中小分子碳水化合物含量变化进行了测定分析.结果显示海藻糖和甘露醇在暗褐网柄牛肝菌子实体中含量较高,生长过程中变化幅度大,其中豌豆期到采收期海藻糖含量增加13.72倍.结果揭示海藻糖和甘露醇在暗褐网柄牛肝菌碳源物质的转运中起到主要作用.在栽培基质添加海藻糖和甘露醇能够起到增产效果,其中海藻糖增产幅度达4.15％.本研究结果对进一步揭示暗褐网柄牛肝菌营养生理规律及改进栽培基质配方具有参考价值.
Abstract
At present,there is limited research on the nutritional physiology of Phlebopus portentosus,and there are no reports on the changes of micromolecule carbohydrates in the fruiting body of P.portentosus at different growth stages.In this study,the content of micromolecule carbohydrates in fruiting bodies of P.portentosus was determined and analyzed at different stages of fruiting body growth.The results showed that the content of trehalose and mannitol was relatively high in the fruiting bodies of P.portentosus,and the range of change was great during the growth process.The trehalose content at harvest stage was 13.72 times that at initial stage.Trehalose and mannitol played an important role in the transportation of carbon source in P.portentosus.Adding trehalose and mannitol to the culture medium increased the yield of fruiting bodies,and the yield increased by 4.15％when solely adding trehalose.Further research on revealing the nutritional and physiological rules of P.portentosus and improving the formula of culture medium will be continued.
