摘　　要：2010年5月和12月,对福建沿海3个红树林生长区(洛阳江、九龙江口、漳江口)的红树林植物丛枝菌根(AM)侵染状况进行研究。结果表明:(1)红树林生长区中6种植物根内均发现AMF侵染结构,其中桐花树、秋茄、鱼藤和芦苇的丛枝为Arum(疆南星)型;(2)6种植物的丛枝菌根侵染率差异较大,老鼠簕的侵染率最高,鱼藤最低;(3)桐花树和秋茄的丛枝菌根侵染率呈显著差异,而其在不同生长区之间无差异;(4)桐花树和秋茄的丛枝菌根侵染率在不同时间呈显著差异,而钝草的丛枝菌根侵染率在不同时间的差异不显著。To study the symbiosis between arbuscular mycorrhizal fungi （AMF） and mangrove plant species, 102 root and soil samples from 6 plant species were collected in three main mangroves growth zone in Fujian, in May and December of 2010. The main results showed that： （1）AMF infection structures were mostly found in the form of curled and expanded intracellular hyphae, vesicles, which were commonly associated with all the mangrove species we investigated. ＇Arum-type＇ arbuscules were found in Parmentiera cerifera, Kandelia obovata, Derris trifoliata and Phragmites australis; （2）AM infection rate was different in mangrove plant species, with Acanthus ilicifolius the highest and Derris trifoliate the lowest; （3） There were significant differences of AM infection rate existing between Parmentiera cerifera and Kandelia obovata, but no difference among three sampling sites; （4） There were also significant differences of AM infection rate in different period in Parmentiera cerifera and Kandetia obovata, but no significant difference in Stenotaphrum helferi in different period.
