新疆阿瓦提分布的多脂鳞伞驯化培育过程中碳氮比的利用能力研究,为种质资源的保护、菌株保存和驯化提供基础数据。以可溶性淀粉为碳源、以硝酸铵为氮源的不同碳氮比条件下研究了多脂鳞伞的菌落形态、显微特征、生长量、生长速率、生长高峰期、满皿时间、达到总生长量50%的天数。分析表明,多脂鳞伞对7种碳氮比均能利用,当可溶性淀粉与硝酸铵的碳氮比为30∶1时,菌丝体生长速度快、活力强、长势整齐、菌落完整、菌丝体和锁状联合结构完整、发育正常,菌丝体总生长量是74.32 mm。本研究采用适宜的碳、氮源开展碳氮比试验研究,准确反映多脂鳞伞对碳氮比的要求,多脂鳞伞表现出对不同碳氮比利用速率和利用效率的差异。
The research on utilization ability of carbon and nitrogen ratio during the domestication and cultivation of fatty taxodiums in Awati, Xinjiang, provided the basic data for the conservation of germplasm resources and the preservation and domestication of strains. With soluble starch as carbon source and ammonium nitrate as nitrogen source, the colony morphology, microscopic characteristics, growth rate, growth rate, peak growth period and full dish time were studied under the conditions of different C / The number of days of growth 50%. The results showed that all the seven kinds of carbon and nitrogen ratio could be utilized by S. sclerotiorum. When the ratio of soluble starch to ammonium nitrate was 30:1, the mycelium grew fast, had strong vigor, grew well and the colonies were intact. The combined structure of the filament and the lock is intact and the development is normal. The total amount of mycelium growth is 74.32 mm. In this study, suitable carbon and nitrogen sources were used to carry out C / N ratio experiments to accurately reflect the C and N ratio requirements.
