Detailed explanation-1: -Trees with ring-porous xylem form wide earlywood vessels (EWV) in spring and narrow latewood vessels in summer. The wide EWV become embolized or blocked with tyloses by the end of the growing season while the narrow vessels may remain functional for many years.
Detailed explanation-2: -Hardwoods may be divided into ring-porous and diffuse-porous trees. In ring-porous trees the vessels laid down at the beginning of the growing season are much larger than subsequent vessels laid down at the end of the season (or ring). Diffuse-porous trees form vessels of roughly the same radial diameter throughout…
Detailed explanation-3: -WOOD TYPES Ring-porous woods include species such as the oaks, hickories, and ashes. These species are the most desirable in the forest. The diffuse-porous woods include red maple and blackgum. Diffuse-porous woods are usually less desirable and used in products of lesser value.
