Thus, according to the researchers, the vascular system present in trees must maintain hydraulic resistance to ensure efficient movement of water and nutrition through the tree, and for this characteristic, at a certain point Da Vinci’s rule ceases to apply.
It is noted that in order for fluids to move successfully from the bottom to the top, the vascular channels in trees must have a certain size in order for resistance to be maintained, so closer to the end of the plant, its volume must become smaller, causing the capillary ratio to be much higher.
