| 中文摘要: |
| 探讨不同丛枝菌根真菌促进土沉香（Aquilaria sinensis）、降香黄檀（Dalbergia odorifera）、檀香
（Santalum album）等珍贵树种生长的效应，筛选促进生长的AM 菌株，为丛枝菌根真菌应用于珍贵树种提
供理论依据。通过温室盆栽接种试验，3 种珍贵树种分别接种幼套近明球囊霉（Claroideoglomus etunicatu，
CE）和摩西斗管囊霉（Funneliformis mosseae，FM），探讨这两种菌株对珍贵树种幼苗生长的促进作用。结
果表明，土沉香以接种FM 菌株的生长量和生物量积累较高，降香黄檀以接种CE 菌种的生长量和生物量积
累最高，接菌组对檀香生长和生物量影响较小；根系形态特征结果表示，3 种珍贵树种接菌后均能不同程度
促进根系长度、根表面积、根体积生长。主成分分析（PCA）结果显示，3 种珍贵树种能较为各聚为一类，
对生长因子和根系因子的响应不同。 |
| 英文摘要: |
| The study was done to understand promotion effects of Arbuscular mycorrhizas fungi on growth of rare
tree species Aquilaria sinensis，Dalbergia odorifera and Santalum album by comparing the advantages of selected
strains to provide a theoretical basis for rare species growing. Under a greenhouse pot，three rare tree species were
through root inoculation of AM fungi：Claroideoglomus etunicatu（CE） and Funneliformis mosseae（FM），and the
promotion effects of the two strains of CE and FM fungi were studied. The results showed that the seedling growth of
A. sinensis with inoculation of FM fungi were high，and the growth effect of D. odorifera seedling inoculated with CE
fungi was good. Nevertheless，there was no significant difference on the growth and biomass of S. album seedlings
by inoculation treatments. The morphological characteristics of root showed that the root length，root surface area
and root volume of three rare tree species were promoted to different degrees after inoculation. Principal component
analysis showed that three rare tree species could be each together as a class，which the growth factors and root factors
were various sensitive. |
