Effect of girdling on phloem and xylem formation in a range of gymnosperms and angiosperms

What is it about?

Phloem and xylem cells are formed by the division of cambium cells. We investigated the response of the cambium to girdling. Different species of woody plants (Scots pine, Siberian fir, European aspen, and gray alder) were selected. We girdled trunks during active growth and collected phloem and xylem samples at the end of the growing season. We characterized the anatomical changes that occurred in the phloem and xylem of different species after girdling. These results are important for understanding how the cambium responds to wounding and changes in source-sink relationships under changing environmental conditions.
