Cerasus avium

'Cerasus avium'' Moench. – Wild cherry'''

group: 	SEMI-RING-POROUS HARDWOODS

Macroscopic structure of wood

heartwood/sapwood: 	heartwood

description: 	narrow sapwood (1–3 cm), yellowish white to slightly pinkish; heartwood yellowish brown to reddish brown; longitudinal stripes (greenish yellow, dark reddish brown) rings: 	distinct boundary between rings; distinct zone of early wood and late wood in rings

vessels	only micropores in wood (longitudinal sections smooth); lighter layer of early wood within a ring due to higher abundance of micropores

rays: 	numerous ray flack, visible only in R

texture: 	flatsawn (T), radial figure (R) and burl (T); very luster and very decorative wood

other: 	texture and colour are very decorative
