[Correlation between rhizospheric microorganisms distribution and alkaloid content of Fritillaria taipaiensis].

In order to reveal the relationship between the amount of soil microorganisms and the quality of Fritillaria taipaiensis, both cultivated and wild F. taipaiensis were collected from Chongqing, Wuxi at different stages of their growth as objects of the research. The mycorrhizal infection rate and colonization intensity, peimisine and total alkaloid content in bulbs, the amount of microorganisms and biomass carbon content in rhizospheric soil were all determined using common methods.
