采用盆栽试验的方法，以不同剂量的丛枝菌根真菌菌剂接种印度紫檀幼苗，测定其根系中AMF的侵染率、苗木的生长指标及光合指标，研究菌剂对印度紫檀幼苗的接种效应。结果表明， AMF接种处理后，在印度紫檀幼苗根系中的侵染率较高，接种不同剂量菌剂侵染率可达72.5％～77.67％；接种217天后印度紫檀苗高比对照增加39.69％～72.0％、地径增加19.51％～48.78％、生物量增加58.15％～220.26％；净光合速率、气孔导度、胞间CO2浓度、蒸腾速率明显高于对照，增强了叶片的光合作用；印度紫檀幼苗对菌剂的依赖性属于中等强度（158.15％～289.87％）。在所试验的4个剂量中，以接种10 g／株的处理对印度紫檀幼苗的生长效果最佳，其次是15 g／株的处理。

The objective of the study was to assess the inoculation effects of arbuscular mycorrhizal fungi ( AMF) on seedlings of Pterocarpus indicus.Using Myco Apply Endo, the AMF inoculants introduced from US as the materials, four different applying amounts namely 5 g/seedling , 10 g/seedling , 15 g/seedling and 20 g/seedling were test-ed.The root AM colonization ratio, seedling growth and photosynthetic parameters of seedlings were measured and analyzed .The results showed that high root AM colonization ratio were detected in inoculated seedlings , with the colonization ratio of 72.50 %~77.67 %.Two hundred and seventeen days after inoculation , compared with the control, the height, basal diameter and biomass of inoculated seedlings increased by 39.69 % ~72.0 %, 19.51%~48.78 %and 58.15 %~220.26 %respectively.Besides, the net phytosyntheric rate (Pn), stoma-tal conductance ( Gs) , intercellular CO2 concentration ( Ci) and transpiration rate ( Tr) of the inoculated seedlings were significantly higher than the control.The mycorrhizal dependency of Pterocarpus indicus was 158.15 %~289.87 %.Among the four tested applying amounts of inoculant, the effect of 10 g/seedlings was the best, and followed by 15 g/seedlings .
