引进外来或非本地树木可能会失败，由于缺乏合适的真菌合作伙伴。我们在中国西南部的贵州省西峰市种植了外来的辐射松。以松乳菇（Lactariusdeliciosus）为外生菌根真菌（EcMF），研究了辐射松幼苗的引种策略，以及在新的生境中与当地的EcMF形成熟悉/新的联系，以了解辐射松如何在2.5年的时间内成功建立。株高和针叶养分的获得，共同引入L。松孢霉属真菌，并对根际土壤和根尖真菌群落组成进行了分析。此外，当地土壤的温室生物测定实验，以评估外来和本地松树幼苗之间的EcMF社区的差异也进行了。结果表明，辐射松在西峰人工林中无论是否共引，都能在西峰人工林中定植。美味的将L.松毛虫在新地区已结实2年，且在菌根际土壤中相对丰度较高，可能与辐射松一起归化。L.松毛虫预定殖显著改变了菌根真菌的组成，并与辐射松的氮素吸收量呈正相关。外来辐射松和本地马尾松在造林初期或种植园均能吸收到相似的本地真菌群落，因此寄主身份对真菌群落组成没有影响。广布种扁乳牛肝菌（Suillusplacidus）相对丰度较高，与辐射乳牛肝菌（P. radiata）形成了一个共同群丛。温室生测实验进一步表明，乳牛肝菌与辐射松形成外生菌根，贡献了相对较高的胞外酶总量，而辐射松和马尾松同一类型的外生菌根表现出不同的酶功能。我们的研究表明，外来辐射杨可以通过与共同引入的L.但在大规模种植辐射松时应谨慎。L.松毛虫在种植园中持续存在，因此应关注松毛虫的引入对当地EcMF群落的影响。美味的
An introduction of exotic or non-native trees may fail due to a lack of suitable fungal partners. We planted exotic Pinus radiata in Xifeng, Guizhou Southwest China. Strategies to introduce P. radiata seedlings either colonized with an ectomycorrhizal fungus (EcMF), Lactarius deliciosus, or expect them to form familiar/new associations with local EcMF in a new habitat were studied to know how P. radiata could be successfully established over a period of 2.5 years. Plant height and needle nutrient acquisition, the persistence of the co-introduced L. deliciosus, and fungal community composition in rhizosphere soil and root tips were analyzed. In addition, a greenhouse bioassay experiment of local soil to assess the differences in the EcMF community between exotic and native pine seedlings was also conducted. The current results demonstrated that P. radiata could establish in the Xifeng plantation with or without co-introduced L. deliciosus. The co-introduced L. deliciosus might be naturalized with P. radiata in the new area since it has been fruited for 2 years with high relative abundance in mycorrhizosphere soil. L. deliciosus pre-colonization significantly altered the mycorrhizosphere fungal composition and it had a positive correlation with nitrogen acquisition of P. radiata. Host identity had no effect on fungal composition since exotic P. radiata and native P. massoniana recruited similar local fungal communities in early establishment or in plantation. The cosmopolitan species Suillus placidus, with high relative abundance, formed a familiar association with P. radiata. The greenhouse bioassay experiment further showed that Suillus sp. contributed relatively higher total extracellular enzymes by forming ectomycorrhizas with P. radiata and the same type of ectomycorrhiza of P. radiata and P. massoniana showed different enzymatic functions. Our study indicated that exotic P. radiata could be a suitable tree capable to get established successfully in the Xifeng plantation either by interaction with the co-introduced L. deliciosus or with a local EcMF, but we should be cautious about large-scale planting of P. radiata. L. deliciosus persisted in plantation and more attention should be paid to local EcMF community changes induced by the introduced L. deliciosus.
