Les brez por, branike razločne, razločen rani in kasni les. Wood without pores, distinct annual growth rings, distinct earlywood and latewood.
Brez smolnih kanalov. Without
resin canals.
Prehod med ranim in kasnim lesom
postopen. Gradual transition from the
earlywood to the latewood.
Smolni kanali številni, vidni s
prostim očesom. Resin canals
numerous and visible to the
naked eye.
Smolni kanali majhni in vidni z
lupo. Resin canals small, visible with a
magnifying glass.Prehod med ranim

Les s trahejami, v prečnem prerezu vidnimi kot pore, branike razločne ali nerazločne. Wood with vessels, which in cross-section appear as pores, growth rings both distinct and non-distinct.
Les difuzno porozen Diffuse-
porous wood.
Trakovi niso vidni s prostim očesom. Rays
not visible to the naked eye.
Trakovi niso vidni z lupo.
Rays not visible by means of magnifying
glass.
Trakovi vidni z lupo. Rays
visible by means of
magnifying glass.
Trakovi na radialnem prerezu
vidni kot zrcalca. Rays on radial
section visible as ray flecks.
Na tangencialnem prerezu trakovi
vidni kot vretena; lahko daljša od 1
cm. On tangential section rays
visible as fusiform structures, may be higher than 1 cm.
Trakovi razločno vidni s prostim očesom. Rays
clearly visible to the naked eye.
Širokiagregirani
trakovi vidni na prečnem
prerezu. Wide aggregate rays
visible to the naked eye in
cross-section.
Trakovi dveh velikosti: široki
in ozki. Rays of two distinct
sizes: wide and narrow.
Trakovi na tangencialnem
prerezu vidni kot 1-3 mm visoka
vretena. On tangential section
rays visible as1-3 mm high
fusiform structures.
Les venčasto porozen.
Ring-porouswood.
Trakovi razločno vidni
s prostim očesom. Rays clearly visible to the naked
eye.
Pore ranega lesa otiljene,
plamenast izgled tkiva kasnega lesa.
Earlywood pores with tyloses, very
small latewood pores in radial arrangement.
Trakovi s prostim
očesom niso vidni. Rays not
visible to the naked eye.
Pore kasnega lesa razporejene raztreseno, vidne
z lupo. Small latewood pores
solitary or in small groups, visible
by means of magnifying glass.
Pore kasnega lesa v valovitih tangencialnih
pasovih, vidne s prostim očesom. Small
latewood pores grouped in wavy tangential
bands visible to the naked eye.
