• Entity URI: https://w3id.org/APD/traits/trait_0013117
• Type: numeric
• Definition: A vascular tissue morphology trait [TO:0000470] which is the ratio [PATO:0001470] of the count [NCIT:C25463] of groups of xylem vessels [PO:0025417] to the total count of xylem vessels, with a value approximating 1 indicating a tendency towards solitary vessels.;Vmf; A vessel grouping index, calculated as the number of groups of vessels divided by the total number of vessels, where vessels are considered to be part of the same group if they are in contact with one another. A Vmf value approximating 1 denotes a tendency towards solitary vessels while a smaller value indicates a tendency of vessels to occur in clusters.
