| 中文摘要: |
| 采用稳定碳同位素分析方法对羊肚菌的营养方式进行了研究。发现山西省关帝山庞泉沟自然保护区羊肚菌生境中的δ13C= -24‰为菌根营养型/腐生营养型分界线；菌盖呈黑色、有纵脉的羊肚菌为腐生营养型，菌盖呈污黄色的羊肚菌为菌根菌营养型；云南、四川、北京等地羊肚菌的营养方式呈现相似规律。 |
| 英文摘要: |
| The differences of stable carbon isotopic compositions were analyzed for clarifying the trophic manner of Morchella spp. The results showed that EM/SAP (etomycorrhizal fungi/sprophytic fungi) divide was δ13C=-24‰ in the habitat of morels from the Pangquangou Nature Reserve, Guandi Mountain, Shanxi Province, and that the morels with black pileus are saprophytic and those with yellow pileus are mycorrhizal. Similar patterns are founded in the samples collected from Yunnan, Sichuan and Beijing. |
