| The growth rings are distinct, sharply delineated by narrow bands of dark brown latewood. |
|
| Sporadic pitting is present but only in the last few rows of latewood tracheids. |
|
| Its annual growth rings are fairly easy to see and the transition from earlywood to latewood is abrupt. |
|
| He found ring widths increased and percentage latewood decreased with increased spacing. |
|
| Few teased out the seasonal climate signal recorded in the narrow part of the growth ring laid down in late summer known as latewood. |
|
| The difference in colour between the tamarack's earlywood and darker toned latewood creates an attractive striped pattern that makes for eye-catching furniture and finishing lumber. |
|
| Transition from earlywood to latewood is usually abrupt. |
|
| Latewood cells are somewhat smaller than the early wood cells, and have a much thicker cell wall and much smaller lumen, accounting for the darker color of the latewood. |
|
| In inferior oak, this latewood is much reduced both in quantity and quality. |
|
| A clear boundary can exist between earlywood and latewood, representing a false tree ring. |
|
| As conditions worsen, the radial diameters of the secondary tissue cells decrease and the walls may thicken, and the wood may take on the appearance of latewood. |
|
| Finally, the latewood tracheids are formed, with small radial sizes and greater cell wall thickness. |
|
| The outer portion formed later in the season is then known as the latewood or summerwood. |
|
| In temperate softwoods, there often is a marked difference between latewood and earlywood. |
|
| Hence the greater the proportion of latewood, the greater the density and strength. |
|
| The width of ring is not nearly so important as the proportion and nature of the latewood in the ring. |
|
| It is not only the proportion of latewood, but also its quality, that counts. |
|
| No satisfactory explanation can as yet be given for the exact mechanisms determining the formation of earlywood and latewood. |
|
| The latewood will be denser than that formed early in the season. |
|
| In choosing a piece of pine where strength or stiffness is the important consideration, the principal thing to observe is the comparative amounts of earlywood and latewood. |
|
|
|
| In specimens that show a very large proportion of latewood it may be noticeably more porous and weigh considerably less than the latewood in pieces that contain less latewood. |
