Determination of Ectomycorrhizae

DEEMY collects descriptive data on ectomycorrhizae, including extant character descriptions and definitions. Ectomycorrhizae are mutualistic structures formed by fungi and the roots of forest trees. They are predominantly found in the temperate and boreal climate zones but occur also in humid tropic regions, as well as in soils of poor nutrition. Without mycorrhizae, trees would not be able to take up water and minerals. Ectomycorrhizae show a wide range of anatomical diversity which represents their possible function in tree nutrition and ecology. Their anatomical data, in general, allow a quick determination and provide at the same time ecologically important information about possible functions for tree nutrition.DEEMY数据集收录外生菌根（ectomycorrhizae）的描述性数据，涵盖现存的形态特征描述与定义。外生菌根是真菌与林木根系形成的互利共生结构，主要分布于温带与寒带气候区，但也见于湿润热带区域以及贫瘠土壤中。若缺乏菌根，林木将无法吸收水分与矿物质养分。外生菌根具有丰富的解剖学多样性，这一特征体现了其在林木营养与生态过程中可能发挥的功能。总体而言，其解剖学数据不仅可实现快速鉴定，还能同时提供与林木营养相关的潜在功能等具有生态学价值的重要信息。
