For example, these two species have distinct differences with respect to the transition from earlywood to latewood with Douglas-fir having an abrupt transition and white fir having a gradual transition.
Previous work on spin--spin relaxation rates in wood suggested that MR measurements could differentiate lumen water in earlywood and latewood owing to different cell cavity sizes.
First, the data from five representative oak sites were collected and combined for a regional approach where the obtained chronologies displaying the earlywood, latewood and annual growth (i.
A second reconstruction of PDSI values was made for east-central Mexico by using the earlywood width chronology derived from ancient Douglas fir trees at Cuauhtemoc la Fragua, Puebla (Figure 1, panel B).
The anatomical demarcation between rings is readily identifiable in most conifers due to formation of denser, darker latewood at the end of the growing season that contrasts with the lighter earlywood of the following year.
In members of the Thymelaeaceae, tori are especially well-developed in the latewood, and it is thought that this tissue provides a back-up water conducting system in case the earlywood should become embolized (Dute et al.
