Mycorrhizal types of Chilean flora: unpublished data and grey literature

Contact: Dr. César Marín ([e-mail])We present the mycorrhizal type (arbuscular mycorrhizal, ectomycorrhizal, ericoid mycorrhizal, orchid mycorrhizal, non mycorrhizal) of 296 plant species found in Chile (with a total of 341 occurrences), belonging to 94 botanical families. Each occurrence contains information on: plant habit (tree, shrub, perennial herb, etc.), origin (native or introduced), site name, Chilean administrative region, collection date, coordinates, and mycorrhizal type. The mycorrhizal type data comes from three sources (the last two constitute 'grey literature'):1. Stained roots located at Soil Ecology Laboratory, Universidad Santo Tomás, Máfil, Chile; this data has not been published elsewhere. 2.

Forestry Engineering, Austral University of Chile, Valdivia, Chile. Supervisor: Dr. Roberto Godoy B. 3. Conference proceedings: Godoy, R., Vogel, A., Carrillo, R., Hildebrand-Vogel, R. 1994. Zur Bedeutung der Mykorrhiza im Fitzroya cupressoides-Wald Südchiles. Verhandlungen der Gesellschaft für Ökologie 23: 135-141. Methods.For recording the flora and preparing herbarium specimens: Only flowering specimens were collected to obtain suitable material for herbarium deposits and formal taxonomic identification. Preliminary species identification was performed using relevant taxonomic literature. For root collection, species were identified in the field through in situ recognition. The updated flora nomenclature is based on: Rodriguez, R., Marticorena, C., Alarcón, D., Baeza, C., Cavieres, L., Finot, V. L., ... & Marticorena, A. (2018). Catálogo de las plantas vasculares de Chile. Gayana Botánica, 75(1), 1-430. Mycorrhizal type: Root samples from five plants of each vascular species were collected and stored in labeled nylon bags. These were then transported to the laboratory and, using clean forceps, placed in airtight plastic jars for fixation in 50% alcohol. The fixed and stained roots were processed and subsequently examined under a stereomicroscope and an optical microscope to visualize the different types of mycorrhizae.

L., ... & Marticorena, A. (2018). 《智利维管植物名录》（*Catálogo de las plantas vasculares de Chile*），《Gayana Botánica》，75(1), 1-430。 菌根类型检测方法：采集每个维管植物物种的5个植株的根系样品，装入标注清晰的尼龙袋中。随后将样品运送至实验室，使用无菌镊子将其转移至密封塑料罐中，以50%酒精进行固定。经固定与染色处理的根系样品，随后通过体视显微镜与光学显微镜进行观察，以识别不同类型的菌根结构。 智利植物菌根类型相关补充资料。若需获取该国更多菌根类型相关信息，可参考以下资源： 1.
