- Abstract
This paper studied the community structure of arbuscular mycorrhizal ( AM) fungi in the rhizosphere soil of different peony ( Paeonia suffruticosa) cultivars grown in Zhaolou Peony Garden of Heze in Shandong Province. A number of parameters describing this community structure, e. g. , spore density, species- and genera composition, species richness, distribution frequency, species diversity indices, and Sorenson' s similarity coefficient, were examined. The species- and genera composition, species richness, and distribution frequency of AM fungi in rhizosphere soil varied with planted peony cultivars. A total of 10 AM fungal species were isolated from the rhizosphere soil of cultivars ' Fengdan' and ' Zhaofen' , 9 species from the rhizosphere soil of ' Wulong pengsheng' and ' Luoyang red' , and 8 species from the rhizosphere soil of ' Hu red' . The spore density was the highest (59 per 50 g soil) in the rhizosphere soil of ' Fengdan' , but the lowest ( 47 per 50 g soil) in the rhizosphere soil of ' Hu red' ; the species diversity index was the highest (1.89) in the rhizosphere soil of ' Zhaofen' , but the lowest (1.71) in the rhizosphere soil of ' Hu red' ; and the mycorrhizal colonization rate was the highest (63. 6% ) in rhizosphere soil of ' Fengdan' and ' Hu red' , but the lowest (52. 7% ) in the rhizosphere soil of ' Wulong pengsheng'. The Sorenson' s similarity coefficient of AM fungal species composition in the rhizosphere soil among the test cultivars ranged from 0. 71 to 0. 95 , being the highest between ' Wulong pengsheng' and ' Fengdan' , and the lowest between ' Luoyang red ' and ' Hu red' . It was concluded that the gene type of peony could change the community structure of AM fungi in rhizosphere soil.
