Integration of water transport pathways in a maple tree: responses of sap flow to branch severing
Original language description
It has been known for a long time that sectored and integrated patterns of vascular systems exist in different species and even within the same tree, depending on its age and history. However, very few publications consider the topology of the vascular pathways between roots and branches. Some results on this important aspect of the vascular system are presented in this paper. They have been obtained with adult maple trees by studying directly the water movement in the stem and root xylem with the heatfield deformation (HFD) method for sap flow measurements. HFD-multi-point sensors were installed at different heights of a Norway maple tree (Acer platanoides L.) along its stem axis. HFD-single-point sensors were installed in three small lateral roots of another sample maple. Experimental treatments (branch severing) triggered changes in sap movement in the stem and root sapwood. The sample trees belongs to the group with an integrated transport system ("integrated pipes"), sharing stem
