Wood specific gravity

Formal name:  stem wood dry mass per stem wood volume per water density
Local identifier:  TOP285
Related Term:  wood density
Definition:  the ratio of the mass (PATO:mass) of a unit wood (PO:secondary xylem) of the stem (PO:stem) assessed after drying to its volume (PATO:volume) and water density
Formal Unit:  mass unit / volume unit * volume unit / mass unit

Comment:  foresters distiguish three wood specific gravities: basic wood specific gravity (oven dry mass per green volume per density of water at 4.4?C), air dry wood specific gravity (oven dry mass per air dry volume at specific moisture content per density of water at 4.4?C ), oven dry wood specific density (oven dry mass per oven dry volume per density of water at 4.4 ?C)
