Outline of Final Research Achievements

The hair roots of ericaceous plants are in symbiotic association with ericoid mycorrhizal fungi. Ericoid mycorrhizas play very important roles in acquisition of nutrient of their host’s and the high tolerance to the stresses by factors with in the acidic soils. In this study, the mycorrhizal colonization conditions and the microbial flora in the hair roots of blueberries and Vaccinium oldhamii Miq. in Japan were investigated. The mycorrhizal colonization levels of these plants were high and the microbial floras were different among the cultivated area. These results indicate that the growing conditions may affect the microbial floras in the hair root of blueberries.
