摘　　要：川黄柏是芸香科黄柏属黄皮树(Phellodendron chinense Schneid.)的干燥树皮,为著名川产道地"三木"类药材之一,其主要药用活性成分为小檗碱,具有广谱抗菌性,临床应用广泛。通过温室盆栽接种试验,观察了2属7种丛枝菌根真菌对川黄柏幼苗生长及小檗碱含量的影响。结果表明:丛枝菌根真菌促进了川黄柏幼苗的生长,菌根幼苗的株高、地径、根生物量和地上部生物量均高于无菌根幼苗。丛枝菌根的形成影响了川黄柏幼苗根皮和茎皮中小檗碱的代谢。与无菌根幼苗比,菌根幼苗的小檗碱含量均显著提高,且菌根幼苗之间小檗碱的含量差异显著。The Phellodendrom chinense is the dry cortex of Phellodendrom chinense Schneid. in family Rutaceae, as one of three distinguished ＂the three wood medicine materials＂ in Sichuan. Berberine is the main active constituent for medicinal purposes, as well known for its widespread clinical practice as broad-spectrum antimicrobial. This article observed the effect of seven kinds of Arbuscular mycorrhizal fungi belonging to two genera on the growth and berberine content in Phellodendrom chinense seedlings through potted experiment in the greenhouse. The result indicated that AM fungi promoted the growth of Phellodendrom chinense seedlings. And the height and biornass were higher than those of non-mycorrhizal seedings. The formation of AM affected berberine metabolism in root xylem and stem xylem of Phellodendrom chinense seedlings. Compared to non-mycorrhizal seedings, the beberine content was ramarkably higher, and the difference was also significant between myeorrhizal seedings.
