Abstract

Abstract: The effects of AM fungi on the growth and microelement of Scuteliaria baiealensis Goorgi under different N-applied levels in the pot culture were studied． The results showed that AM fungi significant increased mycorrhizal infecting rate， baicalin， the content of Ca of shoot， total P， the content of Fe and total N of root under thesame N-applied levels． Under different N-applied levels， on mycorrhizal plants， mycorrhizal infecting rate， the content of K of shoot， baicalinand and the content of Ca of root were significant differenced． The content of K， Ca， Mg，Zn and Fe of shoot significantly increased under N₂ － N₃ level． AM fungal inoculation was conducive to the growth ofScuteliaria baiealensis Goorgi and increase the content of chemical components of seedlings． The inoculation effect ofAM fungi was the best under 0． 08 － 0． 12 g /kg．

Key words: AM fungi, N-applied level, Growth amount, Microelements, Scuteliaria baiealensis
