• Type: numeric
• Definition: A vascular tissue morphology trait [TO:0000470] which is the proportion of a cross-section of stem that is not comprised of lumen (`empty space`) and is calculated at 1 minus the ratio [PATO:0001470] of total xylem vessel [PO:0025417] and tracheid [PO:0000301] lumen [PO:0025117] cross-sectional [NCIT:C63795] area [PATO:0001323] to stem [PO:0009047] cross-sectional area.;The fraction of a stem cross-section not comprised of lumen (the empty space in xylem vessels and tracheids) and calculated as one minus the ratio of the total cross-sectional area comprised of xylem vessels and tracheids (lumen fraction) to the total stem cross-sectional area.
