(A): [H1A:166] Juniperus old stem wood with extremely narrow growth rings indicating very slow growth under dry and cold conditions [45]; (B): [H1A:171] Amygdalus round wood showing successive years of suppressed growth (narrow rings) after cutting, followed by period of growth release [45]; (C): [H1A:176] stacked and stitched image of Amygdalus round wood showing large rays and sparse pore distribution; (D): [H1A:167] Amygdalus large twig/small round wood: similar to (B) with bands of narrow rings indicating that it originated from a plant that was repeatedly cut [45]; (E): [H1A:175] similar to (A); (F): [H1A:175] Amygdalus stem wood with very narrow growth rings indicating slow growth under cold and arid conditions.
