三七丛枝菌根（AM）的研究

Study on Arbuscular Mycorrhizae of Panax notoginseng

摘要:

研究发现，丛枝菌根真菌（AMF）能侵染三七根系并形成典型的丛枝菌根（AM），侵染率在12%~30%，但侵染强度较弱。从三七根际采集的10个土样中共分离出15种AMF，Glomus属11种，Acaulospora 属4种，分别是瘤状无梗囊霉、刺无梗囊霉、孔窝无梗囊霉、细齿无梗囊霉、地球囊霉、明球囊霉、缩球囊霉、单孢球囊霉、近明球囊霉、地表球囊霉、小果球囊霉、摩西球囊霉、何氏球囊霉、晕环球囊霉和网状球囊霉。其中，地球囊霉是三七的优势种。因此，AMF是三七丰产栽培中的一种潜在应用价值的生物资源。

Abstract:

Arbuscular mycorrhizal fungi can infect the roots of Cercidiphyllaceae and form arbuscular mycorrhizae.Infection rate is from 12% to 30%，but infection strength is weak.4 species of Acaulospora and 11 species of Glomus were isolated and identified，including Acaulospora tuberculata，A.spinosa，A.foveata，A.denticulate，Glomus geosporum，G.clarum，G.constrictum，G.monosporum，G.laroideum，G.versifome，G.microcarpum，G.mosseae，G.hoi，G.halonatum and G.reticulatum.Among them，G.cercidiphyllorum is advantage species.So AMF may be a potent resource of biology which can stimulate the growth of Panax notoginseng.
