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。

Abstract: 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 Kandelia obovata, but no significant difference in Stenotaphrum helferi in different period.

Key words: mangrove plant, arbuscular mycorrhiza, infection rate
