文摘内容 With both field investigation and pure culture experiments, the occurrence and optimal essential growth of mycorrhizal fungi with oaks in Dandong Region of Liaoning Province, China were investigated from 1997-2002. A total of 36 species of mycorrhizal fungi associated with oaks were observed. The results showed that the occurrence of mycorrhizal fungi was related to tree species, tree ages, and months of the year, with at least 20 fungi species being associated with more than two oak species. The highest Simpson index (SI) and Shannon index (H') values, 0.95 and 4.44 respectively, were found in the 15-25 year-old age group. The optimum month for fungal occurrence was August, when the SI and H' values were 0.97 and 5.16, respectively. Additionally, the cultivated mycorrhizal fungus grew best at temperature of 25-30℃ and at PH of 5-6.The results also indicated that the association between mycorrhizal fungi and oaks was common。
