Xylem anatomical and hydraulic traits of trees with different wood properties in a temperate forest in northeast China
【Objective】 Xylem anatomy affects the water transport efficiency and drought resistance of trees, which in turn affects tree growth and survival. Therefore, studying xylem anatomical and hydraulic traits will enable a better understanding of the response and adaptation mechanisms of trees to environmental changes. 【Method】 Here, we measured xylem anatomical and hydraulic traits in 20 tree species with three different wood properties (11 diffuse-porous, 5 ring-porous, and 4 non-porous) in a temperate forest in northeastern China. Our aim was to examine the differences in stem anatomical and hydraulic traits of tree species with three different wood properties and explore the potential relationships between stem hydraulic and anatomical traits. 【Result】 We found that there were significant differences in the anatomical traits (mean vessel (tracheid) diameter, maximum vessel (tracheid) diameter, vessel (tracheid) density, mean vessel (tracheid) area, proportion of lumen area), and hydraulic traits (theoretical hydraulic conductivity, hydraulic diameter, vessel (tracheid) mechanical strength, Huber value) among the tree species with different woody properties (P<0.05). The ring-porous trees had the highest theoretical hydraulic conductivity, whereas the non-porous trees had the highest tracheid mechanical strength. Theoretical hydraulic conductivity was significantly correlated with all anatomical traits. Huber values (sapwood area/leaf area) were significantly correlated with all anatomical traits (P<0.05), except vessel (tracheid) wall thickness and maximum vessel length. However, there were no significant correlations between wood density and all anatomical traits (except vessel length). 【Conclusion】 We concluded that wood density cannot better reflect the hydraulic traits of trees in temperate forests in northeastern China and that their water transport capacity is dependent on the xylem anatomical structure and the balance between a tree’s supply and demand for water.
