[Variation of morphological and anatomical traits of fine roots of three plant species in Xiao-xing'an Mountains, China].

We measured the morphological and anatomical traits of fine roots with 1-5 order in needleleaf species of Pinus koraiensis, broadleaf species of Acer mono, and shrub of Corylus mandshurica, with the aim to understand trait variations among root orders and species. The results showed that there was no significant difference in root diameter and root length among the three species, but was significant inter-specific differences in other traits. The stele diameter (117.
