The summerwood is narrow, but dark in color in the heartwood. |
The outer portion formed later in the season is then known as the latewood or summerwood. |
The springwood is filled with large pores, the summerwood with smaller ones. |
The annual rings are variable in width, and the proportionate amounts of springwood and summerwood also vary. |
It builds up the annual ring, first the springwood very rapidly, and then the summerwood more slowly. |
The wood is very strong, hard, and compact, and the annual growth ring is largely dense summerwood. |
