Interpretive Summary:

Technical Abstract: The spread of emboli in Vitis vinifera is modeled by using reconstructions of three-dimensional xylem networks derived from High-Resolution X-ray Computed Micro-tomography (microCT) images. The incorporation of real network data into the model provides the first quantification of the effects of vessel arrangement, vessel diameter, and intervessel pitting on the susceptibility of the plant to the movement of emboli and pathogens. Of the network parameters analyzed, the shape of xylem network vulnerability curves was most sensitive to perturbations of the number of vessels initially embolized and the pit membrane pore diameter and frequency.
