Riparian ecosystems are among the most degraded worldwide as they are subject to a range of human-mediated disturbances at different scales. As riparian vegetation plays a key role in maintaining waterway and landscape health, restoration often focuses on promoting riparian vegetation re-establishment. The role of below-ground processes and agents in the process of revegetation is often overlooked even though agents like mycorrhizal fungi enhance seedling establishment and plant growth. In this study we aimed to understand whether colonisation by local mycorrhizal fungi can be advantageous to the early phases of plant establishment during revegetation, whether revegetation technique influences the extent of this potential colonisation, and has the potential to enhance revegetation outcomes. We examined mycorrhizal colonisation rate and species composition of root fungal communities in direct seeded and tube-stock plants and compared them with local native vegetation in a retarding basin in Victoria, Australia, then modelled the relationship between root fungal community attributes and plant size. Results indicate that revegetation technique influenced the colonisation rate, diversity and composition of root fungal communities. Moreover, greater fungal diversity and greater similarity of fungal communities to the mycobiota of native vegetation were positively related with growth of seeded plants but showed negative or little relationship to size of tube-stock plants. High colonisation rates of plant species studied, and relationships between fungal community characteristics and plant growth of seeded plants provide the first evidence of the potential importance of mycorrhizal associations for these plant species in a revegetation context.

河岸生态系统是世界上退化最严重的生态系统之一，因为它们受到各种规模的人为干扰。由于河岸植被在维持水道和景观健康中起着关键作用，因此恢复通常集中在促进河岸植被的重建上。尽管诸如菌根真菌之类的药剂会增强幼苗的生长和植物的生长，但地下过程和药剂在植被恢复过程中的作用经常被忽略。在这项研究中，我们旨在了解在植被恢复期间，局部菌根真菌的定殖是否对植物建立的早期阶段有利，植被重新种植技术是否会影响这种潜在定殖的程度，并具有增强植被恢复结果的潜力。我们检查了直接播种和试管植物中根真菌群落的菌根定殖率和物种组成，并将其与澳大利亚维多利亚州一个减速盆地中的本地原生植被进行了比较，然后对根真菌群落属性与植物大小之间的关系进行了建模。结果表明，植被恢复技术影响根真菌群落的定殖率，多样性和组成。此外，更大的真菌多样性和更大的真菌群落与原生植被的分枝杆菌的相似性与种子植物的生长呈正相关，但与试管植物的大小呈负相关或几乎没有关系。研究的植物物种高定殖率，
