Abstract Our study aimed to explore Arbuscular mycorrhizal fungi (AMF) colonization and spore density for Aegiceras corniculatum and Acanthus ilicifolius across five mangrove ecosystems in southern China, focusing mainly on the relationships between AMF and biotic/abiotic factors. Soil physicochemical properties and seawater salinity, as well as the numbers of culturable soil microbes (bacteria, fungi and actinmycetes) were measured to analyze their potential effects on AMF colonization. The results showed that AMP were very common for both plant species in the investigated mangrove ecosystems, and hyphae were the dominant structures for both species. Total AMF colonization rates (TC%) ranged from 0.33% to 36.50%, while the average TC% for A. ilicifolius (13.47%) was slightly higher than for A. corniculatum (9.47%). The average spore density for A. cornicaelatum was 49.0 spores per 25g air dried soil, and 51.7 for A. ilicifolius. Soil physicochemical analysis showed that soil in mangroves was with high moisture and organic matter content, slightly acidic pH, low levels of total and available P and high levels of N content. Microbial counting experiment recorded high microorganism numbers in mangroves. Data analysis revealed that soil available P content and seawater salinity may be important factors influencing AMF in mangroves. The two mangrove species showed different correlations with microbial numbers, which may illustrate that host plant is a key factor influencing AMF and other microbes.
