The phrase "age ring" is correct and usable in written English.
It is typically used in the context of dendrochronology, referring to the concentric rings in a tree trunk that indicate the age of the tree.
Example: "By counting the age rings, researchers can determine how old the tree is and analyze its growth patterns over the years."
Alternatives: "growth ring" or "tree ring".
As you walk the winding pathways of the shire's best kept secret, look out for a 5th century BC iron age ring ditch and the Godolphin Arabian horse grave.
Mr. Danz works from notes on a small card, which includes spaces for iris size in millimeters and descriptions of the collaret, the ring of color nearest the pupil; the freckles and flecks of light in the iris; the limbus, the line between the sclera (the white part of the eye) and the cornea; and the arcus senilis, or age ring, soft and white, around the iris.
Taxon, cambial age, ring width and aspect were highly significant as explanatory variables in wood-density models.
Subsequently, mixed-effects models were developed to evaluate cambial age, ring width, distance from pith, edge effect and aspect as suitable candidate explanatory variables.
A Bronze Age ring and a late Bronze Age sherd were excavated nearby.
The tree's age rings thus evenly stripe the faces of the boards, making them resistant to both warp and flex.
They walked through to the wooden veranda at the back, where there were a couple of porch swings with wheat-colored cushions and a long, low table much scarred and stamped with the marks of the many dewed-over glasses that were set down on it through the years, another form of age rings.
In this way, "age rings" similar to tree rings were obtained.
Each piece holds within it, its secret age rings, just as surgical skin grafts might embed and conceal true age.
At the time of sampling for wood property measurement and microarray experiments, the cambial ages (ring numbers at breast height) of the sampled trees in the Flynn and Kromelite trials were 7 and 6 yrs, respectively, both of which were producing juvenile wood.
The high sample size coupled with the long time series, offers an indication of the effect of tree-ring age, tree-ring width and local climate on wood density of European beech, and highlights as well the high variability between individual trees.
