| Transition from earlywood to latewood is usually abrupt. |
| 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. |
| Its annual growth rings are fairly easy to see and the transition from earlywood to latewood is abrupt. |
| Few teased out the seasonal climate signal recorded in the narrow part of the growth ring laid down in late summer known as latewood. |
| 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. |
