丛枝菌根促进植物的生长和养分吸收，并且在80%的陆地植物中形成。关于热带土壤中丛枝菌根的状况，目前还没有什么资料。本研究的目的是澄清菌根定植的树种生长在热带泥炭土。在2000年和2001年收集了生长在印度尼西亚加里曼丹中部泥炭沼泽森林中的14个科22个树种的幼苗。根用0.05%苯胺蓝染色，在复合显微镜下观察到丛枝、囊泡和内部菌丝。22种植物中有17种表现出丛枝菌根定殖。首次观察到丛枝菌根在尖叶山龙眼、山龙眼、尖叶山龙眼根中的定殖（Dipterocarpaceae）、硬叶红厚壳、红厚壳（Guttiferae）、木立木（Doxylum arborescens）（Guttiferae）、光滑四分孢（Tetramerista glabra）（四分枝科），Palaquium gutta（Sapotaceae）、Mexula melabathricum（忍冬科）、班康树（百里香科）、巴西橡胶树（大戟科）和Campnosperma auriculatum（漆树科）。C. soulattri，C. arborescens，木麻黄G. bancanus、马占相思（Acacia mangium）、M. melabathricum和H. brasiliensis表现出50%或更高的菌根定殖百分比。在龙脑香科的坡垒、云实科的光果木、桃金娘科的拟三重木、红树科的圆叶Combretocapus rotundatus和夹竹桃科的中柱山龙眼中未发现丛枝菌根侵染。接种丛枝菌根真菌可以促进泥炭沼泽林中某些树种的早期生长，有望成为泥炭沼泽林改造的关键技术。
Arbuscular mycorrhizas improve the growth and nutrient uptake of plants and are formed in 80% of all land plants. Little information is available on the status of arbuscular mycorrhizas in tropical soils. The objective of this study was to clarify mycorrhizal colonization of tree species grown in tropical peat soils. Seedlings of 22 tree species in 14 families grown in a peat swamp forest of Central Kalimantan, Indonesia were collected in 2000 and 2001. Roots were stained with 0.05% aniline blue and arbuscules, vesicles and internal hyphae were observed under a compound microscope. Seventeen of 22 species showed arbuscular mycorrhizal colonization. Arbuscular mycorrhizal colonization was observed for the first time in roots of Shorea teysmanniana, Shorea balangeran, Shorea uliginosa (Dipterocarpaceae), Calophyllum sclerophyllum, Calophyllum soulattri (Guttiferae), Cratoxylum arborescens (Guttiferae), Tetramerista glabra (Tetrameristaceae), Palaquium gutta (Sapotaceae), Melastoma melabathricum (Melastomataceae), Gonystylus bancanus (Thymelaeaceae), Hevea brasiliensis (Euphorbiaceae) and Campnosperma auriculatum (Anacardiaceae). C. soulattri, C. arborescens, G. bancanus, Acacia mangium, M. melabathricum and H. brasiliensis showed a percentage mycorrhizal colonization of 50% or higher. No arbuscular mycorrhizal colonization was found in Hopea mengarawan (Dipterocarpaceae), Koompassia malacensis (Caesalpiniaceae), Tristaniopsis whiteana (Myrtaceae), Combretocapus rotundatus (Rhizophoraceae) and Dyera costulata (Apocynaceae). It is suggested that inoculation of arbuscular mycorrhizal fungi can improve the early growth of some tree species grown in peat swamp forests and this will be expected as a key technology to rehabilitate disturbed peatlands.
