| Abstract: |
| Soil samples from the 0～10 cm、10～20 cm、20～30 cm and 30～40 cm depths were collected monthly between July and December 2004,the correlation of temporal and spatial distribution of colonization of AM fungi round the rhizosphere of Raspberry to soil factors was analyzed.The result indicates that the good symbiosis between AM fungi and raspberry was formed.AM fungal colonization and spore density was used to assess and compare the responses of AM fungi to soil condition.The mean percent colonization and spore density of AM fungi reached maximal values of 86% in September and 130 pre 1g soil in November 2004,respectively.Soil alkali solution N had a significant negative effect on spore density,and soil organic matter presented negative correlation to spore density.Soil pH had a negative effect on hyphae percent colonization,and a significant negative effect on vesicle percent colonization.This study results suggest that spore density round the rhizosphere of host-plants and the different structures of AM fungi are the useful indicators for evaluating changes in soil ecosystems. |
